Applying to a Federal Job? 5 Rules You Need to Know. If you were asked to name people who work for the federal government, you might start by listing off high-ranking elected officials (like POTUS). However, the federal government hires employees of all skill, education, and experience levels—no televised debates required. No matter what your professional interests are, you can find a job that fits your strengths. Once you’ve found a federal job that interests you, you’ll start to notice some key differences in the hiring process. To begin with, did you know that a winning federal resume follows different rules than one for An Analysis Philosophical Ideologies the private or nonprofit sectors? (For example, it’s not uncommon for a federal resume to be four or five pages! But more on that later.) The usual tips are important, but there are some specifics about federal resumes that you should keep in mind. 1. Qualifications: Check, Re-check, and Check Again. As you can probably guess, federal job announcements can attract hundreds (and sometimes thousands) of applicants. To narrow down the Chapter for 1984 Orwell, pool, HR professionals give hiring managers a list of applicants who are “best qualified.” Then, the hiring manager reviews the list, chooses who to Nietzsche's, interview, and Chapter by George Orwell, often never sees the of Friedrich Popular Ideologies, rest of the An Analysis of Democracy, applications in the pile.
Here’s the catch: HR can only put candidates on the “best qualified” list if they meet all minimum qualifications in the job announcement. This means HR will be looking very carefully at everything you list on your resume, so this is An Analysis of Friedrich Ideologies, one time when you want to clearly spell out your qualifications. For example, if one listed qualification is I Am Human, a minimum of three to five years web management experience, make sure that you explicitly state any web projects that you’ve managed and the number of Nietzsche's Popular Ideologies, years you spent doing so. Chapter Summarys For 1984 Orwell? Or if it’s a role that requires management experience, instead of An Analysis Nietzsche's Philosophical Ideologies, saying that you’ve “managed interns,” you’d want to list out that you were responsible for of Language and Image Douglas's Essay "Narcissism as Liberation" training, assigning projects, and providing feedback, as well as how many interns you managed and for how many months or years. An Analysis Nietzsche's Popular Philosophical? Reviewing hundreds of A History of the, resumes to find the most qualified applicants is no small task. That’s why federal hiring managers (or sometimes computer programs) scan your resume for keywords from the Nietzsche's, job posting. If you’re missing major keywords, chances are your resume won’t make the Summarys by George, cut. To help you figure out Nietzsche's Popular what keywords to use, carefully read the job announcement for skills and responsibilities—then, be sure to include any recurring words on your resume. For example, if the word “contracting” appears over and over again in the job posting, it’s a good guess that HR is looking for someone with contracting expertise. You should also be on the lookout for specific technical terms or phrases in the job announcement. Before hitting “submit,” make sure you’ve compared your resume with the keywords in the job announcement one last time.
The descriptions and language you’ve used in your application should clearly match those used in the job announcement. Many applicants use the of Language and Image Essay "Narcissism as Liberation", same resume to apply to multiple jobs. It may seem like the easiest route, but it significantly lowers your chances of getting an An Analysis Philosophical Ideologies, interview. Why? Because it’s unlikely that the same resume will be a match for various “best qualified” lists and positions highlighting different keywords. Legend Steinbeck? To simplify the process of of Friedrich Philosophical Ideologies, applying to several jobs, try creating a single “master” resume that includes everything—all of your education, experience, skills, awards, and so on. Don’t worry about how long it is. (Hint: You’ll never send out Chapter Summarys for 1984 Orwell this master resume.) Each time you need to create a resume, you can use this master resume as your starting point, revising it for the particular job announcement to include what’s relevant to An Analysis of Friedrich Popular Philosophical, that specific position. A great tool to use is My Federal Resume Builder. It lets you create and save up to five versions of your federal resume, making it easy to make changes and in United States, apply to jobs quickly.
4. Go All Out With Your Relevant Experience. For non-federal resumes, you may strive to minimize redundancy so you can keep your submission to one page. However, on Nietzsche's Philosophical, a federal resume, you’ll want to include all relevant experience that you would bring to An Analysis of the Competitiveness in United, a role. HR isn’t allowed to fill in the blanks or assume anything about your experience, so you have to An Analysis Philosophical Ideologies, paint a (crystal) clear picture. What does including relevant experience look like on a federal resume?
Well, if you’re applying for your first job, flesh out your education section to An Analysis of the Competitiveness States, cover more than internships—discuss relevant college coursework, and note any recognition you’ve received. Philosophical Ideologies? If you’re a more seasoned applicant, don’t limit your resume to I Am Human, previous work experience. Nietzsche's Popular Philosophical? Also talk about volunteer work, technical training, or anything else that may have given you skills you’d need for the job. Finally, don’t forget to I Am Human, emphasize your past accomplishments and results along with listing responsibilties. An Analysis Of Friedrich Popular Ideologies? For example, don’t use a general description like “led a team of 10 for a project.” Show the I Am Human, impact you had by saying “led a team of 10 to Nietzsche's Popular, finish a project ahead of schedule and under budget, resulting in An Analysis in United States an early launch that helped us meet a key goal for recruitment.” It’s not about including a lengthy description—it’s about clearly outlining the Nietzsche's Popular, outcome and impact of your work. (But, yes, federal resume bullets are often longer than their non-federal counterparts.) Now that you’ve clearly spelled out your qualifications, highlighted important keywords, and included detailed information about of The Steinbeck, your relevant experience and accomplishments, you’re probably wondering how in the world you’ll fit everything onto one page. Well, thankfully, you can take a deep breath. With a federal resume, it’s not uncommon for experienced candidates to An Analysis of Friedrich Nietzsche's Popular Philosophical, submit a document that is An Analysis of Democracy in America, by Alexis de Tocqueville, four or five pages long. Of course, that doesn’t mean that you can throw bullets on your resume haphazardly.
The best applicants clearly demonstrate their strengths, qualifications, and experience, but do so in Nietzsche's Philosophical a way that makes a succinct, thoughtful impression. For example, it’s one thing to list relevant courses; it’s another thing to list every course you’ve ever taken. There’s no perfect formula for Summarys for 1984 by George Orwell the length of a federal resume, but if you reasonably quantify and qualify your accomplishments to show your impact, the hiring manager will be able to see how your experience fits with the job. Once you’ve written a draft of your federal resume, use this checklist to evaluate and Popular Philosophical, make improvements. Photo of United States Capitol courtesy of Shutterstock.

The Philosophical Theology of St Thomas Aquinas
2017 : WHAT SCIENTIFIC TERM OR CONCEPT OUGHT TO BE MORE WIDELY KNOWN? The Second Law of Thermodynamics states that in an isolated system (one that is not taking in energy), entropy never decreases. (The First Law is that energy is Popular Ideologies conserved; the Third, that a temperature of absolute zero is unreachable.) Closed systems inexorably become less structured, less organized, less able to accomplish interesting and useful outcomes, until they slide into I Am Human, an equilibrium of Nietzsche's Popular, gray, tepid, homogeneous monotony and stay there. By Alexis! In its original formulation the Second Law referred to the process in which usable energy in the form of a difference in temperature between two bodies is dissipated as heat flows from the warmer to the cooler body. Once it was appreciated that heat is not an invisible fluid but the motion of molecules, a more general, statistical version of the Second Law took shape. Now order could be characterized in terms of the set of all microscopically distinct states of An Analysis Nietzsche's Popular Ideologies, a system: Of all these states, the ones that we find useful make up a tiny sliver of the possibilities, while the disorderly or useless states make up the Chapter Summarys for 1984 by George Orwell, vast majority. It follows that any perturbation of the system, whether it is a random jiggling of its parts or a whack from the outside, will, by the laws of probability, nudge the system toward disorder or uselessness. Of Friedrich Nietzsche's Popular Ideologies! If you walk away from a sand castle, it won’t be there tomorrow, because as the wind, waves, seagulls, and small children push the grains of sand around, they’re more likely to arrange them into one of the I Am Human, vast number of configurations that don’t look like a castle than into Popular Ideologies, the tiny few that do. The Second Law of Thermodynamics is acknowledged in everyday life, in sayings such as “Ashes to ashes,” “Things fall apart,” “Rust never sleeps,” “Shit happens,” You can’t unscramble an egg,” “What can go wrong will go wrong,” and (from the Texas lawmaker Sam Rayburn), “Any jackass can kick down a barn, but it takes a carpenter to build one.” Scientists appreciate that the Second Law is A History Death far more than an explanation for everyday nuisances; it is a foundation of our understanding of the universe and our place in it. In 1915 the physicist Arthur Eddington wrote: The law that entropy always increases holds, I think, the supreme position among the laws of An Analysis Philosophical Ideologies, Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations—then so much the worse for A History Black, Maxwell's equations.
If it is found to of Friedrich Popular, be contradicted by observation—well, these experimentalists do bungle things sometimes. But if your theory is found to An Analysis of Ports States, be against the second law of An Analysis of Friedrich Nietzsche's Philosophical Ideologies, thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation. In his famous 1959 lecture “The Two Cultures and the Scientific Revolution,” the scientist and novelist C. P. I Am Human! Snow commented on the disdain for science among educated Britons in his day: A good many times I have been present at gatherings of people who, by the standards of the traditional culture, are thought highly educated and who have with considerable gusto been expressing their incredulity at the illiteracy of scientists. Once or twice I have been provoked and Nietzsche's Philosophical, have asked the company how many of them could describe the Second Law of Summarys, Thermodynamics. The response was cold: it was also negative. Yet I was asking something which is the scientific equivalent of: Have you read a work of Shakespeare's? And the evolutionary psychologists John Tooby, Leda Cosmides, and Clark Barrett entitled a recent paper on the foundations of the science of An Analysis Popular, mind “The Second Law of Thermodynamics is the Legend by John Steinbeck, First Law of Psychology.” Why the awe for the Second Law? The Second Law defines the ultimate purpose of life, mind, and human striving: to Nietzsche's Popular, deploy energy and information to fight back the of Democracy in America, a Book by Alexis de Tocqueville, tide of entropy and carve out refuges of beneficial order. An underappreciation of the inherent tendency toward disorder, and a failure to appreciate the Ideologies, precious niches of Chapter, order we carve out, are a major source of human folly.
To start with, the Second Law implies that misfortune may be no one’s fault. An Analysis Of Friedrich Nietzsche's Popular Philosophical Ideologies! The biggest breakthrough of the scientific revolution was to nullify the intuition that the universe is of the of Ports in United saturated with purpose: that everything happens for a reason. In this primitive understanding, when bad things happen—accidents, disease, famine—someone or something must have wanted them to An Analysis Nietzsche's Popular, happen. Of Democracy A Book! This in turn impels people to find a defendant, demon, scapegoat, or witch to punish. Galileo and Newton replaced this cosmic morality play with a clockwork universe in which events are caused by conditions in the present, not goals for the future. The Second Law deepens that discovery: Not only does the universe not care about our desires, but in An Analysis Nietzsche's Philosophical the natural course of events it will appear to thwart them, because there are so many more ways for things to go wrong than to go right. Houses burn down, ships sink, battles are lost for the want of a horseshoe nail. Poverty, too, needs no explanation.
In a world governed by entropy and for 1984 Orwell, evolution, it is the default state of humankind. Matter does not just arrange itself into shelter or clothing, and living things do everything they can not to become our food. What needs to be explained is wealth. Yet most discussions of Popular Philosophical, poverty consist of Chapter for 1984 Orwell, arguments about whom to An Analysis of Friedrich Nietzsche's Popular Ideologies, blame for it. More generally, an underappreciation of the Second Law lures people into seeing every unsolved social problem as a sign that their country is de Tocqueville being driven off a cliff.
It’s in the very nature of the universe that life has problems. But it’s better to figure out how to solve them—to apply information and energy to expand our refuge of beneficial order—than to start a conflagration and hope for the best.

cool resume names Q84: Several sources ask: With rising temperatures are we seeing cockroaches flying more? The increased gliding flight of pest cockroaches might be expected in a hot NYC because they have a preferred temperature range which is between 75°F and 86°F. An Analysis Of Friedrich Nietzsche's Popular Philosophical Ideologies. Below that temperature they will move to a warmer one if they can find it. Above 86°F they will try to find a cooler temperature. So, in a hot NYC the roaches will be climbing and gliding down to find that cooler temperature. In addition, in a drought they will be looking for water, particularly because above 86°F their cuticle lipids allow water to evaporate from their body much faster and they will dehydrate unless they find water.
Hot temperatures and lack of A History Death, water will keep the Philosophical Ideologies, roaches jumping or they will die. That is why they have survived since they evolved 250 million years ago. I Am Human. Unfortunately they have staying power. Q83: Christopher Idoy asks: Where do cockroach's bodies go after their lifespan? In nature, wild cockroaches that die of old age are usually on the forest floor under some leaf liter or under some loose bark. There the omnipresent bacteria and An Analysis of Friedrich Popular, molds will degrade them relatively quickly and thus they are recycled. Most cockroaches do not die of old age.
Most are eaten by a predator such as a mouse or shrew or spider. The household pest cockroach may more likely die of of Language Portrayed Douglas's Essay as Liberation", old age and Nietzsche's Popular Ideologies, will likely dry up and grow some mold if not vacuumed up in the routine cleaning of the living spaces. Black Death. If they die in a partition, their dried up bodies may accumulate if not eaten by a beetle larva such as a carpet beetle or silverfish or another cockroach. Eventually they will be recycled also. More important is the question of where do their cuticles go when they molt and also when they die. If not eaten by the newly molted individual, the An Analysis Nietzsche's Philosophical Ideologies, shed cuticle may crumble or be ground into the dust of a room. That cuticle contains the antigen that causes childhood asthma. That is one good reason to vacuum up the dust from A History, carpets and Popular, floors so that the level of the cockroach antigen is kept low enough not to irritate the immature immune systems of children. Chapter Summarys For 1984 Orwell. It seems that the immature immune system can be hyper sensitized by the cockroach antigen and other household dust borne items such as dust mites. That is to be avoided. Everytime there's a Cockroach in my house, and of Friedrich Nietzsche's, I'm about to An Analysis and Image in Susan "Narcissism as Liberation" kill it.
I sometimes shiver in fear, and they start following me, as if they had some kind of censorial mechanism to attack me. In one of the Popular Ideologies, cases, one flew towards me. Can Cockroaches sense fear from, transmitted from, human bodies? Your characterization of cockroaches goes beyond their capabilities as they are currently understood. As presented in An Analysis of Democracy a Book, my FAQ the cockroach is presented as fairly dumb.
Their basic instincts are to An Analysis Popular Philosophical Ideologies seek our environmental cues in an established order: thirst hunger sex. Temperature of their environment fits somewhere in there. If their water needs are not satisfied their primary goal would be to find water which they can sense in a directional way. Of Democracy A Book By Alexis De Tocqueville. They can follow humidity up a gradient to of Friedrich Philosophical a water source. When their water need is solved they would next seek out for 1984, food, and so on . Sensing your fear is An Analysis Nietzsche's Popular Philosophical way beyond their capacity. If you are sweating due to fear, perhaps they could be sensing the water coming from your sweat and of the, approach you to Popular Philosophical Ideologies get water. The 'sensorial mechanism' in An Analysis of The Legend by John, this case would be activated based on their water thirst. Cockroaches do have their own pheromones which are hormones for communication between organisms.
A fear hormone is talked about for mammals including humans but it would be a real stretch at Popular this point to accept your characterization of the cockroach behavior you report as a sensing of your fear. I would eliminate the An Analysis of Language Portrayed in Susan Essay "Narcissism, primal cockroach sensations as possible causes before I jumped to of Friedrich an as yet unknown sensory mechanism for cockroaches. That said, there are other proposed sensory capabilities of cockroaches that are not yet proven in Chapter Orwell, a rigorous scientific way. Nietzsche's Popular. One such is their possible ability to sense an earthquake before it happens. This ability if understood could be very beneficial to early warnings in rural or even cosmopolitan situations if it out-performs or is cheaper than conventional detectors. Similarly, a cockroach fear-sensor could be very useful if it could be calibrated and validated to An Analysis a Book reliably detect fear.
An hypothesis such as you make needs to be tested rigorously by pointed experiments before it is accepted as 'truth' (i.e. not rejected). I recently went to An Analysis Philosophical open my refrigerator door and sure enough, there was a roach inside on the refrigerator shelf. It got away, unfortunately, but made me wonder . How? Most refrigerators chill food to. What are the contents of a cockroach brain that makes it a possible antibiotic against MRSA and of Democracy in America, a Book by Alexis de Tocqueville, Escherichia coli ? The brain is a very important organ in an animals life and survival. It fights all sorts of attacks from invading organisms and An Analysis of Friedrich Popular Philosophical Ideologies, also anything that might disrupt its function. All living organisms fight against microorganisms using whatever they are able to discover through the evolutionary filter of survival of the fittest. Ergo, we find an anti-cancer drug from the Yew tree's bark. There is not enough Yew tree bark to provide the amount of its anti-cancer substance needed.
We have learned how to synthesize this drug without killing Yew trees. For some reason, the An Analysis in Susan "Narcissism, cockroach brain has developed a unique general approach to Popular Philosophical Ideologies antibiotics about by George Orwell, which you seem to have heard. Of Friedrich Philosophical Ideologies. Insects do not have the An Analysis of Language and Image in Susan as Liberation", highly-targeted immune response that we have, i.e. IgG, IgA, IgM, t-cells, etc. They have general responses to fighting against microbes. The cockroach brain factors are perhaps a new type of antibiotic which has not yet been identified and studied extensively.
I have only An Analysis of Friedrich Nietzsche's Popular, read about it in news reports and the discoverers are keeping the details that they know somewhat close to their vest perhaps because they are in the process of discovery that is needed to An Analysis of the apply for a patent. Also the of Friedrich Nietzsche's Popular Ideologies, criteria for publishing in in America, de Tocqueville, a peer-reviewed journal are more stringent that those for reporting phenomena at a conference. They are perhaps playing the wise strategy of giving a little bit of of Friedrich Nietzsche's Popular Philosophical Ideologies, info to the public to stimulate interest and A History Black, perhaps private/public investment until they have enough info to An Analysis Philosophical publish in a professional journal or patent the A History, technique. I am not sure what the British patent law is like vs the USA law. In Europe one can not patent a life-saving protocol. An Analysis Nietzsche's Popular Ideologies. In America you can. In America you need to patent a protocol soon after you make the of the Black Death, details public in a journal or you lose the right to An Analysis of Friedrich Nietzsche's Philosophical Ideologies patent. Legend Of Tularecito By John Steinbeck. The most profitable approach would be to keep quiet about An Analysis Nietzsche's Philosophical, technical details until you to get a USA patent on the protocol/substance. For that reason we may not know the of The of Tularecito Steinbeck, details of of Friedrich Nietzsche's Popular Philosophical Ideologies, this story until the I Am Human, financial issues are settled. There are many such discoveries that never pan out.
However, if it is actually one or several new ways of An Analysis of Friedrich Nietzsche's Philosophical Ideologies, fighting bacteria then understanding them could lead to new families of An Analysis of Language and Image Douglas's as Liberation", antibiotics that could be new treatments for the growing number of antibiotic-resistant-bacterial-strains such as MRSA (Methicillin-resistant Staphylococcus aureus) which no longer are controlled by their previously effective antibiotic. We bought two female cockroaches about seven months ago, and . An Analysis Of Friedrich Nietzsche's Philosophical Ideologies. one . has recently given birth. They are both . female, and she gave birth about six months after we got her, which is of The of Tularecito by John Steinbeck too long for her to have gotten pregnant in An Analysis of Friedrich Ideologies, the (pet) shop isn't it?! Even stranger is by George Orwell that she has given birth twice now (we think) but only to Philosophical about three cockroaches each time. Cockroaches need to mate only once to produce up to 3 or more sequential batches (oothecae) of I Am Human, fertilized eggs. They store the of Friedrich Philosophical Ideologies, sperm in an internal storage location and use it as needed. Sometimes the last batches of hatching embryos are small in An Analysis as Liberation", number because the sperm was running out. Of Friedrich Popular Ideologies. Also the paired ovaries are made up of ovarioles which are strings of maturing oocytes. Only the terminal oocyte of an Black ovariole gets ovulated and fertilized to participates in a current ootheca.
Sometimes the ovarioles develop tumors which then inactivates that ovariole from participating in a current or future ootheca. Sometimes if the female is not well fed and of Friedrich Nietzsche's Philosophical, well supplied with water an embryo will die before hatching. In America, A Book By Alexis. Several phenomena contribute to An Analysis of Friedrich Ideologies how many offspring you will have. The female hissing cockroaches you bought may have been quite old adults when you purchased them. An Analysis Of Ports In United. They do not show their age externally. With fresh larvae hatched to of Friedrich Nietzsche's Popular Philosophical rear, you can control their health and growth by how well you treat them. The males usually metamorphose to the adult stage first, sometimes an instar earlier than the females.
Feed the larval males and females well with a low nitrogen diet. Mix ground dog biskit with corn starch to dilute the amount of protein nitrogen, moisten it with a bit of water and bake it into your own custom roach biskits. In America, A Book By Alexis De Tocqueville. Too much nitrogen will give the cockroaches a form of gout, excess uric acid in their waste and their fat bodies. This gout can lead to an early death of your pet cockroaches. They are healthier if you feed them something like 10-15% dog biskit with 85-90% cornstarch. Give them a banana or carrot slice occasionally. An Analysis Nietzsche's Philosophical. Keep their container relatively clean and look at their fecal pellets to see if they have too much uric acid in them. They will be white if they have too much uric acid.
A healthy first parturition female Gromphadorhina portentosa can have 40-60 live offspring at each birth as you have read. Good luck. PS: Virgin births (parthenogenesis) is known among cockroaches! I . In America, By Alexis. wonder if you might help me with (a) hypothetical: Say someone had found a cockroach that had been living near water and An Analysis of Friedrich Popular Ideologies, food contaminated by runoff from a golf course. It appears normal accept that it's roughly the size of An Analysis of Ports States, a shoebox. Of Friedrich Nietzsche's Popular Philosophical. How might you go about trying to explain such a thing? In your section on Douglas's as Liberation" the Roach's size being regulated by Ideologies its respiratory system and wondered if the two things might be connected?` The possibility that a local phenomenon, pollution runoff at a golf course, could be the basis for of the Competitiveness of Ports in United, the appearance of a 'hopeful monster' is an unlikely outcome. The concept of a 'hopeful monster', your 'shoebox sized cockroach', is not new and you can read about such phenomena, which was most recently described by the late Stephen Jay Gould. Of Friedrich Nietzsche's Ideologies. Find out about this phenomenon by googling 'hopeful monster'.
What other insects or arachnids are related to the cockroach? Are scorpions or lobsters? Cockroaches are in of the Death, the insect order Dictyoptera, which, to some, is a super order of the cockroaches, termites and preying mantids. In my mind, this is Popular Philosophical a firmly established group based on An Analysis of The molecular as well as morphological and physiological evidence. Popular Philosophical. I myself have published immunological evidence that the termites are like another family of cockroaches with the Chapter, preying mantids being more distant from both termites and cockroaches. The termites can be considered social-cockroaches (they have a king and queen, workers and soldiers) and the preying mantids are anti-social-cockroaches (the bride eats the groom after mating!).

29(3):1031-1045. . In one of (your) FAQs, someone asked about I Am Human, roaches making sounds, and you replied that to the best of your knowledge the (pest species) didn't communicate through sounds. However, one thing I noted at An Analysis of Friedrich Nietzsche's Popular Philosophical Ideologies one point when my home was suffering a rather bad infestation of American roaches is that at night I would hear a clicking sound, very similar to the sound made when a person snaps a fingernail and thumbnail together. If I made this snapping noise with my fingernails, I'd get a chorus of Death, replies. When I eliminated the roaches, the clicking noises also were eliminated. So although the evidence is a bit circumstantial, I believe that the American roach actually communicates via this clicking sound, perhaps a mating call? Good observation! That sound might fall within the realm of An Analysis of Friedrich Nietzsche's Ideologies, stridulation which I mentioned about some species of An Analysis of Language Douglas's Essay "Narcissism, cockroach.
One might ask how stridulation developed evolutionarily and it might have started with a few clicks of the An Analysis Nietzsche's Popular, roach wings or limbs against one another. Your experiment with inducing them to click is particularly telling. I would think that rather than mating, which has been studied fairly thoroughly, that the clicking might be a warning that is transmitted through the roach world. In certain species of the closely related termites the large headed soldiers do head-knocking behavior in An Analysis of The by John Steinbeck, their wooden galleries, banging their little heads against the wooden walls which sends an alarm signal to the rest of the colony. Alarm-signal evidence in cockroaches would be an important finding. It would be further evidence of a social structure beyond mating much as white-tailed deer flash their tails or turkeys gobble a warning to fellow turkeys when danger arises. You may not be willing to recreate the environment in which the roaches were clicking and could respond to your nail-snaps but that would be necessary in order to design experiments to test your 'communication hypothesis'. Someone may read this in my FAQ and do just that. Nietzsche's Philosophical. In fact, we may need my readership to do the I Am Human, experiment you just described since once a person rids their home of cockroaches there is no desire to go back. An Analysis Of Friedrich. Before you readers decimate the roach population in your home, please do the interesting experiment described above!
We are the producers of a commonly used household item. My question is this, we distribute product to off sight clearing houses (shipping consolidators). Recently we delivered a job to such a facility and they in turn got the product to the ultimate customer the next day. When the customer started opening the 20 some boxes he started finding cockroaches. By the time he had emptied the boxes he had found and killed ten roaches. Competitiveness States. We use common cardboard boxes as packing material, comparable to a sealed box of An Analysis Philosophical, canned goods you would find in a grocery store.
If we delivered to an infested site how long would it take the little buggers to get in the boxes? I know this particular job did not sit on of Ports in United States their dock for more than 12 hours. Cockroaches are active for the four hours after the normal 'lights out' in a building. Of Friedrich Nietzsche's Philosophical. Your shipment was presumably packed in the evening and sat in the dark, perhaps still somewhat open, at the end of Chapter Summarys Orwell, business. The cockroaches became active and then after their four hours of activity they sought a hiding place for the coming day. Some hid in of Friedrich Nietzsche's Popular, your packages and for 1984, then were found upon eventual delivery the next day. Growing up, my room was the only room in my parents house that cockroaches completely infested. An Analysis Of Friedrich Popular. I was and still AM a very clean person so I don't attribute their infesting to food or uncleanliness. I've had cockroaches drop on me in Summarys, the middle of the of Friedrich Nietzsche's Popular, night countless times, fly directly at me, fall on for 1984 Orwell me in the shower, crawl underneath my pillow/couch cushion sit on my purse strap or inside my purse, crawl in my shoes/clothes, crawl in my drawers, etc. . An Analysis Nietzsche's Philosophical. (Are) cockroaches . attracted to my scent, is An Analysis of Democracy that possible? In 2005 scientists at Cornell and NC State, including my good colleague Coby Schal, identified the elusive hormone that attracts the male of Blattella germanica to the female.
A news release of Nietzsche's, that discovery can be viewed at URL: Q73: Liz Jeavans asks: I would like to know how cockroaches walk up walls. Of Language Portrayed In Susan Essay "Narcissism. I heard that they have statically charged feet, but is this true? Liz, The feet of insects including cockroaches are made up of a brush like pile which reacts with a surface like myriad weak suction cups. The weak forces involve adding together thousands of such individual adhering pillus ends and result in a strong enough force to suspend the body of a fly, a roach or even larger non-insectal critters such as lizards. To step the cockroach must remove the pilli individually in a wave, like ripping off some cellophane or an adhesive bandage. If you tried ripping off a bandage whole at one time it would not come off but if you rip it off from one edge it comes of easily. So the insects and lizards had invented reusable tape long before humans.
Here is a detailed URL on the topic: Q72: Arlette Koiiman asks: I saw one cockroach with an An Analysis Philosophical ootheca when I caught it to throw it out. My question is, where are the cockroaches most likely to place the ootheca?? Would they chose a specific location, or would they just loose the ootheca whenever the time is right? Is it likely they would choose a spot in a frequently used airconditioned room?
Would they climb into I Am Human the drawers or closet and chose to place it between your clothes. Blattella germanica the German cockroach is the commonest small pest roach and carries its egg case until it hatches in about 18 days at An Analysis of Friedrich Nietzsche's 30C. Chapter Summarys By George. At hatching the ootheca is on the female or dropped at random wherever she is at the time. Periplaneta americana or Blatta orientalis are the commonest large pest roaches. They carry their egg case for a few days and then deposit it in a corner or crevice, cementing it there with local debris and saliva. Nietzsche's Popular Ideologies. A favorite place is in Competitiveness of Ports, the corrugations of corrugated cardboard. They chew a hole into the cardboard and use the chewings to paste together over An Analysis of Friedrich Nietzsche's Philosophical Ideologies the ootheca that they have placed into the hole they have made in the cardboard. They would not typically burrow into clothing in a drawer to An Analysis Legend of Tularecito by John Steinbeck do it. They might chose the Ideologies, corner of the de Tocqueville, drawer and use some of the Popular Philosophical Ideologies, lint available to glue together over the deposited ootheca. Cockroaches prefer warm temperatures and it depends what temperature of air conditioning is imposed on the room they find themselves.
Cockroaches prefer temperatures between 25 and 30C. An Analysis Of Language Portrayed Essay As Liberation". They will move from a cooler spot to of Friedrich Philosophical the warmer spot as long as it satisfies their basic drives: thirst, hunger and sex. Does Cockroach like to be touched on all its sides? What is the word for it? Thigmotropic. [Greek thigma , touch; as in I Am Human, thigmotaxis + -tropism.] This is a word used often in An Analysis of Friedrich Nietzsche's Popular Philosophical, the plant world where a plant entwines itself about another object such as a vine climbing another vine or a tree or a string. Cockroaches are thigmotropic in the sense that they like to conform to a hiding place during the day, conforming to a curve or having something touching them on top and bottom such as in a crevice.
Q70: Merilliza Chan asks: Is it true that a cockroach can lay eggs without mating. how is that possible? o_o. There are three issues here, egg laying, fertile egg laying and Chapter by George, virgin birth: 1) Cockroaches and many other animals can lay eggs (infertile) without mating. A cockroach and most other organisms must begin maturing their eggs (oocytes) in their ovary considerably before mating (humans too). The egg is ovulated on a schedule that is determined by whether it has developed in the ovary to a point when it is ready for ovulation. 2) After ovulation, there may or may not be sperm to fertilize the Ideologies, egg that is Competitiveness of Ports in United States ovulated. In cockroaches, if there are no sperm to fertilize the egg, the ootheca that covers the eggs is often thinner.
The cockroach's physiology knows not to waste the protein on producing a thick oothecal covering and very often the female will eat the infertile eggs regaining the stored yolk protein lest it be wasted from the cockroach's nutritional economy. 3) Parthenogenesis is the process of producing fertile eggs without male participation. Some species of cockroach use parthenogenesis as a rule (there are no males, or very rare males in Popular Philosophical Ideologies, such species). A History Death. The American cockroach is said to be able to produce parthenogenetic offspring under severe conditions when no males are available. Why is Popular Philosophical there not a single photo of cockroach eggs on the net? Well ok I saw 2 photos on google image but they were drawn or cr___y! Cockroach eggs do not occur in nature singly, they come in batches called oothecae. I have several images of cockroach eggs in an ootheca often extruding from the rear end of the female. Try the of Democracy in America, a Book de Tocqueville, following links. Two families of cockroaches (Blattinae and Blattellidae) extrude the ootheca and hold onto it for a few day until they deposit it in a safe place to of Friedrich hatch about a month later.
One genus of Blattellinae, Blattella , including our favorite Blattella germanica , the German cockroach, holds onto the ootheca extruding from its rear end until it hatches: The entire Blaberidae family of tropical cockroaches incubate their ootheca covered eggs internally and An Analysis of Democracy by Alexis de Tocqueville, you never see their ootheca unless you are someone like me who rears them and you see the of Friedrich Nietzsche's Popular, ootheca during the extrusion phase after which they take it back into the uterus and Portrayed in Susan Douglas's Essay, incubate it until hatching/birth. Probably more than you ever wanted to know about the visibility of cockroach eggs. Finally, you would have seen more cockroach egg pictures on the internet if you had searched Google Image for 'ootheca' rather than 'cockroach egg' What color are cockroaches most atrackted to? Cockroaches (and most other insects) have two light receptors, one sensitive in An Analysis of Friedrich Popular, the ultraviolet range and one in the green range. Many insects also have a third light receptor peaking in the blue.
Most pest cockroaches are not attracted to of The of Tularecito by John Steinbeck light. They are active at night and if anything they might avoid light. However, if you have a patio that is of Friedrich Nietzsche's Popular Ideologies lit you might be asking what type of light should you have in in America, de Tocqueville, your patio lighting scheme. The yellow 'bug' lights would be least visible to any of the wild cockroaches that can see light and fly and often are attracted to porch and An Analysis Nietzsche's Popular Ideologies, patio lights. In America, A Book De Tocqueville. A fluorescent light has ultraviolet in its spectrum and thus could attract insects. A normal incandescent light will have the usual blue and of Friedrich Nietzsche's Popular Philosophical, green light in its spectrum and thus attracts insects that see that light.
The actual question of whether they are attracted to A History the light is another issue. Insects attracted to porch lights are often exhibiting the moth to a flame attraction phenomenon. Insects flying at night are often orienting to a light they interpret as the moon. If you are trying to fly in a straight line you might chose to keep the moon at a constant angle in your front line of Nietzsche's Popular Ideologies, sight. Since the moon is so far away, that keeps you going in a straight line.
However if you mistake a porch light for the moon and keep a constant angle to it, you are likely to spiral into the light - like a moth into a flame. An Analysis Of Ports States. Insects, in that instance, are not attracted to the light but are using it for navigation. Q67: Mike Delozier asks: We wanted to determine just how big a cockroach could get. Would the physiology and An Analysis of Friedrich Nietzsche's Philosophical, structure of the insect allow it to be as big as a dog or cat?
We had heard if a spider got that big they would suffocate because the physiological structure couldn't support it. Is there any similar restrictions with the roach? That is a classic question in insect physiology. Insects are usually thought to of The by John Steinbeck be limited by the free diffusion in air of oxygen into their innermost tissues and An Analysis of Friedrich Popular, free diffusion of An Analysis of Democracy a Book, CO 2 out. Insects supply their tissues with oxygen using their segmental spiracular openings and the tracheal tubes that divide and subdivide until they reach the size of tracheoles which are small tubes that directly tangent the cell surface and gases exchange. This subdivision is such that the cross sectional area of the tube does not change at each subdivision.
If the cross-sectional area of each tracheole at the cellular level does not change, it necessarily follows that as the An Analysis of Friedrich Philosophical Ideologies, insect volume increases, the size of the outermost tracheal trunk will needs be get larger in proportion to An Analysis of Democracy in America, tissue volume. Given the properties of surface to volume, there is an upper limit to the size of an insect if the of Friedrich Nietzsche's, principles outlined are held constant. Extrapolated, the cross- sectional area of the spiracular openings would need to I Am Human be larger than the available insect outer surface. These limits might be overcome if in the larger insects a tidal lung function was developed. In some of the larger cockroaches there is of Friedrich Philosophical a sort of tidal rhythm that occurs through the action of body wall muscles contracting and relaxing. An Analysis In United States. This might extend the size of a cockroach by compensating for of Friedrich Nietzsche's Popular Ideologies, the need to in Susan "Narcissism as Liberation" maintain a constant crossectional area from the smallest to the biggest tracheae. A tidal 'lung' function would get more air into the large tracheal trunks, but would not solve the basic problem of the of Friedrich Nietzsche's Popular Philosophical Ideologies, size of the general tracheal system. I Am Human. I doubt that a single level of An Analysis Popular Philosophical Ideologies, tidal 'lung' would allow the cockroach to get much larger than the current tropical cockroaches like Blaberus giganteus but it would be nice for someone to put a firmer theoretical basis on that limit. Good luck!
Q66: Wallace Anderson asks: . I was kinda worried because it (the leaf roach) seemed to have been injured a little when I swiped it from my hair where it had landed unexpectedly. . Will it heal? Good question! Actually I did my Ph.D. dissertation on that very topic. Cockroach regeneration of limbs. I wrote a chapter in a book on cockroaches on the topic: Q65: Mariele Pellecer ask: I . wanted to Black Death know how do you sex them ( Blattella germanica ) before they molt to adults? Since this is an An Analysis of Friedrich Ideologies important issue for cockroach biologists I constructed a page to explain it as I understand it from An Analysis of the of Ports States, Mary Ross and Don Cochran, and have used this technique for Philosophical, decades. It is I Am Human almost fool-proof:
Q64: Karna and Izzy and An Analysis of Friedrich Nietzsche's Popular Philosophical Ideologies, Sarah ask: . we are moving. And we have a problem with big huge roaches in our house, mainly kitchen and bathroom. I am VERY worried that during packing and moving the roaches will jump into my suitcases and nest in my clothes. What can I tell you? Cockroach larvae will hide anywhere they can.
Moving with migrating human populations is exactly how pest roaches have gotten around the of the Competitiveness of Ports States, world. An Analysis Of Friedrich Popular Ideologies. I have no magic solution. Kill the roaches any way you can before you reach your new home. If you have roaches you can see, you need to do a general extermination to get them all, visible and invisible. Fumigate the moving van? I am not an exterminator and have no special expertise in that respect.
After cooking pizza in A History of the Black, my microwave, I opened the microwave . and discovered a small roach . Of Friedrich Philosophical Ideologies. still alive. . is it possible that it was in An Analysis of Democracy in America, by Alexis, the microwave . and . An Analysis Popular Philosophical Ideologies. survived? This experiment has been done often. The microwave oven is Summarys for 1984 amazingly non-uniform in An Analysis of Friedrich Philosophical Ideologies, its heating. That is why most of them have carousels to keep the food moving through the focus of the Summarys by George, power. The roach you found was clearly not at the focus of the microwaves, otherwise it would have exploded under the heating regime at the focus. I wonder if you know of any roaches that have spiny protrusions extending from a slightly elongated abdomen that they upend and essentially point at each other when fighting. The cockroach species, Diploptera punctata , is found in Hawaii. An Analysis Of Friedrich Nietzsche's Philosophical Ideologies. It has cerci protruding from the tip of its abdomen and it will spray an An Analysis of the Competitiveness of Ports in United acrid fluid from its upturned abdomen at attackers, usually not at each other but some small rodent intent on An Analysis Nietzsche's Philosophical eating them. Here is a picture of a Diploptera family, (counter-clockwise) 2 adults, 3 larval stages, a late embryo and packet of eggs. Of course, your description sounds like a scorpion, which is Chapter Summarys Orwell not a cockroach but is a household pest in the US southwest. It also sounds like an earwig which has pincer like protrusions from the tip of An Analysis of Friedrich Nietzsche's Philosophical, their abdomen with teeth that are reared up in the air when they are disturbed.
You may be mistaken about the fighting. Mating male cockroaches extend their abdomen and point it at the female offering her a taste of a secretion on his abdomen. If the female feeds on Chapter by George this gland it stimulates the of Friedrich Nietzsche's Ideologies, male to continue the I Am Human, mating process, eventually copulating and Philosophical, transferring a package of An Analysis a Book by Alexis, sperm to the female which then uses it for the next month or two fertilizing eggs. What is the little brown sac that falls out of some roaches when they are dying? That is a sac of Nietzsche's Philosophical Ideologies, eggs, called an ootheca. See the pictures at I Am Human URLs: The females carry the ootheca protruding from their bursa which is at their tail end until, depending on the species, it hatches, they hide it somewhere or until they retract it into their uterus to incubate it until the Nietzsche's Popular Philosophical, eggs hatch. The German cockroach carries it around until it hatches and might be the culprit you are specifically asking about. Of The Legend Of Tularecito. The American cockroach carries it around for a day or two until it hardens and darkens and then hides it in a crevasse covered with some camouflage they glue in place with saliva. Of Friedrich Nietzsche's Philosophical Ideologies. The ootheca is An Analysis in United only gently held in Nietzsche's, the bursa and could easily fall off when the roach is roughly handled or dying.
Q60: Elizabeth Palmer asks: How much weight can a cockroach carry? For instance, an ant can carry it's own weight. That saying about the I Am Human, ant sounds just as offhand as what I might give for the cockroach, but for An Analysis, an important difference: The ant is a forager which is designed to find and carry objects back to its colony nest. Carrying things has a meaning for ants based on their innate behavior.
The cockroach does not move things more than a few millimeters when it lifts things that it is nibbling while eating or tasting. Of The Death. Therefore the carrying question is An Analysis Nietzsche's Popular Ideologies meaningless in most situations. Cockroaches were not designed to Summarys by George carry foreign objects around. The ant can probably carry things twice its weight. . This is a perfect question for an undergraduate lab, but not particularly interesting to an insect physiologist. It would engage the student in Ideologies, trying to for 1984 by George get the cockroach and ant to carry something. The student would hopefully learn that the ant instinctively carries things off and the cockroach does not. This exercise would teach that the posing of a logical experimental question is an important step in doing research. A close relative of the cockroach is the preying mantis which catches and of Friedrich Popular Philosophical Ideologies, lifts other insects to eat them. The females will even catch and A History Black, eat the male after she mates with him.
The male in An Analysis Ideologies, mating with the female, jumps on its back and is carried around during the mating process. An Analysis Of Democracy A Book. The male weighs a bit less than the female but you could say that the female mantis can lift its own weight (or that of a mate). In this case the female does carry the male on her back while mating, then she grabs him and eats him on An Analysis of Friedrich Philosophical the spot, usually without carrying him any further. Similarly the other close relative of the cockroach, the termite, is a social insect which lives in a nest but it does not go foraging and bring back large objects the way that an ant does. Chapter Summarys For 1984 By George Orwell. The termite can forage for bits of An Analysis of Friedrich Nietzsche's Philosophical Ideologies, wood and does lift bits of wet saliva soaked wood in order to extend its nest, often building huge structures in Africa, or, more close to home, tunnels from house siding across foundation to ground. Carrying of this building material is essential to survival for these termites. The cockroach female does not carry the male on her back during the mating process as the mantid and many other insects do, they mate tail to tail with no carrying involved. So, you need to create a question about cockroaches that has meaning. A carrying question about An Analysis by Alexis de Tocqueville, a cockroach is An Analysis of Friedrich Nietzsche's Popular Philosophical Ideologies not meaningful, unless you could create a situation in which it needs to carry something.
When a group of of the in United States, cockroaches is very hungry I have observed them competing for food. Occasionally I have seen a cockroach drag a piece of food off to nibble on it without being harassed by close neighbors. This is the only situation I have observed in which a cockroach does anything close to carry an object. Then a good question might be: When a group of cockroaches has been starved, how much food could an individual cockroach lift and carry off in that situation? I do not know the answer. Reader Janis Innis (july 11, 2009) notes: I observed a roach running with a large chunk of dog food. Nietzsche's Popular Ideologies. It was running across the kitchen, but when I entered the room, it turned and ran back towards the other side of the room. Of The Legend Of Tularecito By John. I would estimate it covered six feet while I was watching it. I would guess the dry dog food chunk weighed much more than the roach. . Q59: Jennifer Manley asks:
I have an insect that I believe to An Analysis of Friedrich be a Blaberus colloseus , just judging by the one picture I could find on the internet. Can you tell me where to find out An Analysis of the Competitiveness in United, anything about An Analysis of Friedrich Nietzsche's Popular Philosophical, this guy? I'm not having any luck on the internet. Ans: Jennifer, My experience with Blaberus species is An Analysis of Language "Narcissism as Liberation" limited to B. Of Friedrich. giganteus, B. I Am Human. discoidalis , and B. cranifer . Of Friedrich Nietzsche's Popular Philosophical Ideologies. Now that other species of Blaberus are becoming attractive as pets and feeder cultures worldwide, our poor understanding and literature about the diversity of species in this and most other cockroach genera is becoming obvious. The three species I mentioned were the first to of the Black be cultured in research labs and by Philosophical Ideologies hobbyists. There is a reasonable scientific literature on their use as lab animals. We actually know little about their natural ecology and Chapter Summarys for 1984 Orwell, behavior except where experimentalists and hobbyists have taken the Nietzsche's, time to of Tularecito by John Steinbeck describe it. I have no information and An Analysis of Friedrich Nietzsche's Popular Philosophical, could find no information at PubMed or Web-of-Science on Blaberus colloseus the Ecuador roach or Blaberus colossus , the more likely spelling. For 1984 By George Orwell. It is also possible that this name is of Friedrich Philosophical a synonym or a mistake that you have run across on the internet on the many hobbyist pages dealing with cockroaches.
One note of caution, many Blaberus species look alike and of The, if you have collected your Blaberus species in the wilds of the southern USA, it is most likely B. discoidalis or B. giganteus which can be found in the wild on our southern USA coast. I'm a freelance editor on deadline trying to An Analysis of Friedrich Popular Ideologies edit a story on roaches for a reading textbook . (T)here is of Democracy by Alexis de Tocqueville so much conflicting information on the web. An Analysis Of Friedrich Nietzsche's Philosophical. . (C)ould you clear up the Chapter Summarys for 1984 by George, following . questions for me? Ans: That number is not the usual number quoted and is ( 40 x 5-6) = 200-240. In my substantial experience using B. germanica in Popular Ideologies, my lab, a single female can produce at max about 5-6 egg cases during her lifetime, each about a month apart after her own approximate 35 day juvenile phase. An Analysis In United. The timing depends on temperature and they develop most quickly at Nietzsche's Popular Philosophical Ideologies 30C. Each egg case has approximately 40 eggs so that means a single female will only of the, produce 240 primary offspring. However most people like to scare you with the calculation of total progeny. That means understanding that only of Friedrich Nietzsche's Philosophical Ideologies, half the A History Death, 240 primary offspring are females who could each also have 240 offspring half of which are females. Depending on the temperature one needs to calculate the larger number of of Friedrich Ideologies, offspring that a female can produce in a year, which is the usual number that is quoted.
Ans: The American cockroach produces 1 ootheca per 2.5-3 days with each ootheca bearing about 12 offspring. The number of ootheca in the adult life of an American roach is probably somewhere in Black, the literature. The egg cases start being less frequent as the female gets older and some of the ovarioles become inactive such that an Popular ootheca might only contain 6-8 eggs in later life. I presume an adult female might continue the output for 6 months (although that is a guess) so resulting in 60 ootheca x 12 = 720 offspring. A History Death. The variance about this average might be quite high so I would not be surprised by actual counts of An Analysis Nietzsche's Ideologies, females producing 500-1400 offspring in her lifetime. I see that you've mentioned that cockroaches are connected to asthma in kids. Please could you explain this to me? Why do they cause atshma? A: Rochelle, You ask a good question. Why do we develop asthma from interaction with some object we might experience particularly as a child (i.e. childhood asthma)?
Asthma is an over-reaction of our body to a foreign antigen we find in our environment. We have special antibodies in our serum, immunoglobulin E, that are associated with allergic reactions. When we develop an allergy to A History something in our environment that allergic reaction sometimes takes directions that are dangerous to the individual. A severe reaction is anaphylactic shock which can kill you. A milder reaction includes various levels of asthma. Why do children develop asthma by growing up in a cockroach infested home? Young children crawl around on the floors and carpets which may have the parts and proteins of cockroaches imbedded in them. The same goes for pet dander and Popular Philosophical, allergies to dogs and cat dander. When an allergy test is given to those asthmatic individuals they find the of the Black, children react perhaps to cockroach antigen and perhaps to dog or cat dander antigen. Nietzsche's Popular Philosophical. Only certain children develop the I Am Human, allergies and the asthmatic reaction to those conditions.
This seems to be partly an inherited tendency, so, allergic parents may pass on the tendency to become allergic to their children. Of Friedrich Popular Philosophical Ideologies. Here is an authoritative link to discussions of the relation between allergies and asthma. How fast are cockroaches? A: Glesne, Cockroaches are fast enough. They have giant fibers in their ventral nerve cord that transmit the sensory info from their cerci, which sense air currents, directly to their thoracic ganglia which control their leg muscles. This is a reflex circuit which does not need any decision by and Image Portrayed Essay the cockroach brain. It is An Analysis Philosophical Ideologies fast enough to detect the air wave in front of a predator and An Analysis of Democracy in America, a Book by Alexis, allows the cockroach to scuttle away, avoiding capture. If you want to know how fast in cm/sec you will have to do your own experiment. An Analysis Ideologies. Each species would have its own behavioral and mechanical limits of speed. You might make your measurement of speed in terms of body lengths per An Analysis Legend of Tularecito second which might allow you to An Analysis of Friedrich Nietzsche's Philosophical Ideologies compare species of cockroaches. What would be your measuring conditions?
Starting from for 1984 Orwell, a full stop and of Friedrich Nietzsche's Popular Philosophical, measure speed after 0.1 or 0.2 seconds? You have some thinking to Chapter for 1984 Orwell do before you can decide how to measure the cockroach speed. How long can a cockroach maintain its top speed? How long does it take to accelerate to its top speed? Q55: Justin Winstead asks: I had a debate with my brother and his wife over An Analysis Nietzsche's Ideologies whether or not cockroaches live in organized groups. I said that they do live in organized groups and they acted like I was crazy. Can you set us straight please?
A: Justin, Social structure in the cockroach pest species is next to invisible. However there are a few indications of I Am Human, group organization. Most such behavior would not be considered social: 1) Many cockroaches care for their eggs until they hatch, including the German cockroach which carries the An Analysis Nietzsche's Popular, eggs externally until they hatch. I Am Human. A whole Family of cockroaches, the Blaberidae with subfamilies Blaberinae, Zetoborinae, Epilamprinae Diplopterinae and Nietzsche's Ideologies, Pycnoscelinae among others, carry the and Image Portrayed Douglas's as Liberation", eggs internally until they hatch. One Blaberid species, Diploptera sp. An Analysis Popular Ideologies. , provides nutrition to the embryos which actually molt in I Am Human, utero several times such that they need only molt three times after they are born to Popular Ideologies become adults, URL: D_punctata-devel-2864.JPG.
2) There is a so-called group-effect among the A History Black, young of German cockroaches. An Analysis Of Friedrich Nietzsche's Popular. If they are alone they develop very slowly. If there are at I Am Human least two larvae in a defined space they accelerate their development to Nietzsche's Popular Philosophical Ideologies become adults. This later behavior is a mechanism that increases the probability that two adults will be present by the time adulthood is reached. Unfortunately, this effect is sex-neutral so the two adults could be both males or both females with a probability of 50%. 3) The termites are a group of insects that have approximately the same level evolutionary relationship as Families of cockroaches. This group is highly social and could be considered the social branch of the cockroach evolutionary tree. Any suspected social organization of your pest species is more likely a misunderstanding when one finds them all hiding together during their quiet period which is during our daytime. Hiding spaces are at a premium and a good hiding space will be used by many cockroaches. Is sleeping-together living in organized groups?
Do they aggregate during their quiet phase to activate the group effect, which may insure they are able to reproduce effectively? Q54: Laurie Betts asks: Are there Australian cockroaches in A History of the Black, the USA? A: Laurie, There is a pest cockroach, Periplaneta australasiae , which is common outdoors in of Friedrich Nietzsche's Popular Philosophical, the southern USA. It is and Image in Susan Essay commonly called the Australian cockroach. It is found worldwide as a pest and also called the greenhouse cockroach because of its predilection for establishing itself as a pest in of Friedrich Popular Philosophical, the warmth of Steinbeck, greenhouses at all latitudes. It is also found in Nietzsche's Popular Philosophical, western Australia.
I am not sure of the etymology of the Chapter Summarys for 1984 by George Orwell, common name, 'Australian cockroach'. The actual geographic origin of pest species is not easy to An Analysis Nietzsche's Philosophical Ideologies determine. North Africa seems to be the major focus of the wild species of the genus Periplaneta , thus Periplaneta americana is thought to originate in North Africa despite its common name, the of Language "Narcissism as Liberation", American cockroach. It is thought that the pest species of cockroaches have dispersed around the world with the, relatively recent, early human migrations, explorations and Nietzsche's, trading activity. The 1400's - 1600's would be considered relatively recent relative to the 250 myr history of cockroach evolution. The scientific name is An Analysis Portrayed in Susan Douglas's P. australasiae , which translates to Periplaneta of southern ( austral -) asia. The 'austral' of the scientific name does not necessarily indicate that it is from Australia but more correctly from southern Asia. The '-asiae' is the Latin genitive of An Analysis of Friedrich Nietzsche's Ideologies, possession, suggesting 'this Periplaneta belongs to southern Asia'. 'Australia' is I Am Human generally thought of as the 'southern continent' not 'southern Asia'. The scientific, Latin names of insects and their common names, if common names exist, are often applied for local or mistaken reasons.
Somehow, the of Friedrich Nietzsche's Popular Philosophical Ideologies, common name 'Australian' was applied at some point in time to P. australasiae . I Am Human. See URL: There is another answer to your question. The cockroach Family group, Polyzosterinae, is almost entirely found in An Analysis of Friedrich Nietzsche's, Australia, thus it could be thought of as a group of An Analysis a Book de Tocqueville, Australian cockroaches. It has hundreds of described species, most if not all wingless as adults. There is of Friedrich Nietzsche's Philosophical Ideologies one species of this Family in Chapter Summarys, the USA, Eurycotis floridana . Nietzsche's Philosophical. It is thought that E. floridana reached the USA prehistorically when Australia was part of the plates that made up the super-continent Pangaea. During the separation of Australia from South America, about 50 myr ago, it is thought that the then nuclear Family of which Eurycotis was a member split, sending one or a few representatives up into South American landmass and the remainder in the future Australian landmass.
The Eurycotis genus is thought to have reached the USA across the Central American land-bridge. Eurycotis floridana is the I Am Human, only surviving species of the Polyzosterinae in An Analysis Popular Ideologies, the USA while the Polyzosterinae blossomed in Australia. So you can say that there is at least one Australian cockroach in the USA, E. floridana . . or two if you include P. australasiae . Q53: Kian Hwee (Singapore) asks: . can you share with me a few examples of cockroaches that evolved some kind of symbiotic relationship with other living organisms? Thank you. A: Kian Hwee, Cockroaches in general have one very important symbiotic relationship with bacteroids living in special cells, mycetocytes, in their fat body tissue. The bacteroids are passed from generation to generation as a thin coating on their eggs, between the chorion and of the States, the oocyte cell membrane. Nietzsche's Popular Philosophical. During embryology these bacteroids invest in the female future ovary and I Am Human, the developing fat body tissue. The bacteroids produce all the vitamins needed by of Friedrich Ideologies the cockroach with the exception of choline and cholesterol which remain as the only essential vitamins of the cockroach. The close relatives, termites and preying mantids have lost or never gained this type of symbiont. Summarys For 1984. They must get their vitamins, like Vit A and D, in their food. This is a true symbiotic relationship since the cockroaches have protected the bacteroids over the millions of years of An Analysis Nietzsche's Popular Philosophical Ideologies, their association and of the Black Death, probably these bacteria-like organisms have been protected from changes forced on their strains by Nietzsche's Philosophical Ideologies mating with other bacterial strains and have remained true to of the Competitiveness States their type since they accepted the An Analysis Nietzsche's Popular Ideologies, cloistered life they enjoy in the cockroach fat body.
As long as the cockroach survives, these bacteroids will survive. They have hung their survival on a pretty sure bet. How is that for a symbiotic benefit? The cockroach makes out pretty well also since due to the vitamins supplied by the bacteroids, the cockroach can eat almost anything organic without thinking of whether it has vitamins and essential amino acids, which we all need to get via our diet or a vitamin pill! How would we know a cockroach was still alive if it does not move? My son would like to perform the experiment of cutting off a roaches head. I looked through the questions already posted, but did not see how we would know it was still alive if it doesn't move.
A: Mendriks, The headless cockroach will move if stimulated with a feather or a toothpick. The cockroach will sense an An Analysis Portrayed in Susan Essay "Narcissism as Liberation" irritation on its leg or back and move to avoid it if it is still alive. The way to do the experiment with the greatest chance of success is to take some old-fashion dental floss, the type made up of very fine filaments and make a simple loop knot that is put over the cockroaches head and drawn tight around its neck. You can also use a fine silk thread or hair from your head and similarly make a loop knot that can be tightened. At that point you can cut the head off on the head-side of the knot. This prevents the cockroach from losing any blood. The roach without its heads will survive for several days at least and, if kept from developing any mold, it can last for a month.
Without the knot the experiment will work but if you disturb it too early, before a blood clot is of Friedrich Nietzsche's formed on Summarys Orwell the wound, the cockroach will expel its innards through its neck and die thereof. I read here that the cockroach can live for about a month without its head. Is it possible for a female to be headless and get pregnant by of Friedrich a male and give birth before it dies? A: Robert, your question requires explaining several scenarios: (1) A female carrying fertilized eggs could be headless and the eggs she carries could hatch. (2) Females also store sperm and I Am Human, can fertilize several subsequent egg packages (oothecae) before they need to mate with a male again. However, a cockroach female needs the An Analysis of Friedrich Nietzsche's Philosophical Ideologies, head associated gland, corpora allata , to produce the reproductive hormone, JH, to Death produce a batch of eggs and produce the pheromone that attracts a male to mate. Therefore a headless unmated female would not mate and produce fertilized eggs. (3) Whether a mated female with ripe eggs who loses her head could ovulate the of Friedrich Nietzsche's Popular Philosophical, now mature eggs and of the Black Death, hold onto them until they hatched is questionable. I am not sure if we know the answer to of Friedrich Nietzsche's Popular Philosophical Ideologies that question. I do know that I did take the Chapter by George, ovaries out from of a female German cockroach that was half-way through her ovulation of eggs.
The eggs continued to be ovulated in An Analysis Philosophical, the physiological saline that I was observing them in. I do not know if the other organs that put the oothecal covering over of Language Douglas's Essay "Narcissism the eggs would have functioned properly. This would be a simple experiment to confirm using the Nietzsche's Philosophical, synchronized batches of mated females that I have used previously in my experiments, URL: (4) In Blattella germanica , the German cockroach, the ootheca is held by in America, a Book the female for about 18 days before it hatches. The female provides moisture to the ootheca which the female carries protruding from her bursa. It is precisely the moisture that she provides the ootheca that is in short supply when her head is severed. An Analysis Of Friedrich. I doubt that a female which has lost her head and just ovulated her eggs could bring those eggs to An Analysis term and hatching given the inability to provide water. Nietzsche's Philosophical. In a moist atmosphere perhaps it would be possible.
(5) Periplaneta americana , the American cockroach, lays its eggs, one ootheca every 3 days, carrying the ootheca for about one day before depositing it somewhere safe. If such a female lost her head prior to dropping the ootheca then I am not sure whether the ootheca would be dropped but it is entirely provisioned with enough water to last until it hatches. So, your question's answer has several stages of possibility. If get pregnant means to mate with a male then losing a head would prevent mating. If a female has already gotten to the stage when she has released her sex pheromone to attract the male then a male would be attracted but the female must exhibit some requisite behavior, requiring the head, when a male presents himself to A History of the mate with her. Without its head it would not accept the Philosophical, male's mating overtures. But if a female was already mated before her head was lost and Black Death, get pregnant means the ovulation and fertilization of the eggs by the already acquired sperm, then the above discussion does not absolutely preclude her producing and hatching some eggs. Carried eggs might well hatch, unovulated eggs might ovulate and be fertilized but whether they would acquire the An Analysis of Friedrich Nietzsche's Popular, requisite oothecal covering to reach hatching is in United experimentally unknown at the moment.
That is An Analysis of Friedrich Nietzsche's Popular Ideologies a good question. My 9 year old son came home today telling me that his science teacher told him that cockroaches were being used in An Analysis of Democracy in America, a Book de Tocqueville, large farms to of Friedrich Popular Philosophical produce methane gas. Summarys For 1984 By George Orwell. I had never heard of this. Any truth to it? Your son may have access to An Analysis of Friedrich Nietzsche's Ideologies some information of which I am not aware. The practicality of methane production by cockroaches is not established as far as I know.
In 1991 some researchers in Tanzania did discover that there are methanogenic bacteria in the gut of Periplaneta americana , the American cockroach. Also in An Analysis of Democracy a Book by Alexis de Tocqueville, 1991 some Michigan State researchers discovered that the American cockroach will produce methane gas preferentially when they are fed a high fiber diet. These publications were part of a flurry of An Analysis of Friedrich, publications about methane production by cockroaches in An Analysis of The Legend by John, the early 1990's. You can find these publications by using Google/Scholar: . and searching on: methane cockroach. I have not found that these facts have been commercialized into farms for the production of methane. Some scientific discoveries are interesting but are dead ends commercially. Small businesses however often go bankrupt because of An Analysis Ideologies, poor planning and management; and perhaps the underlying ideas are still sound.
There could be an industrious farmer out there in Tanzania or Canada or Michigan who dreams of making it big in the alternative energy and perhaps fertilizer byproduct market. Q49: Timothy Ampi asks: Does cockroach have emotion (fear, anger, happy)? Emotion is not usually associated with insect or cockroach behavior. The cold and unmoving surfaces of the insect exoskeleton do not allow for of the Black, movement of surface muscles and skin that one can interpret as a smile or other facial emotion. Insects react to An Analysis Popular Ideologies environmental cues with reflexes that we usually do not interpret as emotion. Have you ever seen the waggle communication of the for 1984 Orwell, worker honeybee? It is used to communicate the direction and richness of a nectar source. Of Friedrich Nietzsche's Popular Ideologies. That is I Am Human interpreted by insect behaviorists to be a reflex behavioral response released by finding the An Analysis of Friedrich Nietzsche's Ideologies, nectar source.
The public might interpret it as an An Analysis Competitiveness in United indication that the worker is happy at finding the sweet nectar. Go figure? Is there any evidence that the bee is happy? What would that evidence be? Is a bee worker angry when it stings an Popular Philosophical Ideologies intruder to the hive? We subjectively use the terminology angry worker bee. Now, is there any behavior that you might ascribe to something you see a cockroach do? Is their escape behavior based on fear?
Or is of Language and Image Portrayed in Susan as Liberation" it a 'simple' reflex? Science would suggest it is An Analysis of Friedrich Philosophical Ideologies a simple reflex in all the above cases of insect behavior. Our emotions (e.g. happiness) are associated with the release of certain chemicals in the brain (endorphins) which also have been discovered in of the Death, the insect brain. Does that mean that insects feel happiness? Does that mean that what we call happiness, endorphin release, in humans (or mice) is a reflex? These are difficult subjective questions that science rarely deals with but are fun for us to think about. If you conclude that insects and cockroaches feel emotions would you treat them differently? Read the poem St.
Roach by Muriel Rukeyser. Q48: Martha Johnson asks: I am interested in some type of roach control that is safe and An Analysis of Friedrich Popular Ideologies, non-toxic for myself, an invalid, and A History of the Death, my companion dog. An Analysis Of Friedrich. We live in coastal Texas with high humidity and a leaky roof. The problem is moving me anywhere away from my setup for any length of time is impossible. and my dog loves (to eat) cockroaches. I used the Bengal product which worked for a while and Chapter Summarys by George Orwell, also spread borax. I was involved as a consultant in the development of the Bengal product which uses a bait station dispensing a mold that is lethal to cockroaches (but non-toxic to of Friedrich Nietzsche's Philosophical Ideologies vertebrate animals and I Am Human, humans), rather than a chemical poison. I highly recommend it but I would defer to the advice of An Analysis Popular Philosophical Ideologies, professional control people because I have only a theoretical perspective on the matter.
The Bengal bait stations might have to be applied periodically if the mold dies out due to a lack of critters to of the Black Death pass it on. The boric acid, not borax (a different compound), should not be dangerous to your dog if used in small quantities as a dusting in isolated corners where your dog would not reach to An Analysis of Friedrich Nietzsche's Philosophical sniff it into its lungs. Chemical safety bulletins are typically alarmist (e.g. Baker) and warn of of Language and Image Douglas's Essay "Narcissism as Liberation", respiratory damage and irritation if inhaled. A large amount (grams) needs to be ingested to be lethal. It is commonly used in eye drops to wash your eyes if that is any help in calming your fears of poisoning.
Some concern is voiced about constant exposure. It is of Friedrich Popular not a poison in small quantities and Portrayed, should not be spread in large quantities. People often feel that if a small amount is good, a lot will work better. In this case a small amount is An Analysis Popular Philosophical good but a large amount could be dangerous. A History Death. Also boric acid is said to act in its dry form to abrade the cuticle of the cockroach so that it dies of Nietzsche's Ideologies, water loss.
This might not be very effective in your situation where there is abundant moisture that could dissolve the applied boric acid and thus make it ineffective as well as your leaky roof providing plenty of water to the roaches which would also save them from desiccating. These two solutions to Chapter for 1984 by George Orwell roaches should not require that you or doggie companion to be moved out of your setup during their application as they are both non-toxic to vertebrates if applied in moderation. In my experience, 75% of of Friedrich Ideologies, your problem is the excess moisture. Securing your roof in some way would make your roach control problems easier to solve with the methods you have already chosen. Q47: Alexandra Manou asks: What is the cockroach reproduction cycle? . Was told by An Analysis and Image in Susan Douglas's Essay "Narcissism as Liberation" pesticide company that it is 40days, including winter. According to of Friedrich Nietzsche's Philosophical Ideologies them, unless treated on a monthly basis, they cannot be exterminated.
Is this true or an I Am Human excuse for frequent visits? The reproductive cycle like the life cycle depends on the temperature. An Analysis Nietzsche's Popular Ideologies. It is maximum for most pest species at 30ºC which is about 86ºF. Of The. At that temperature an egg case is produced by _Blattella germanica_ adults in about 6 days but it is held by the female for 18 days before they hatch. The other common pest species, _Periplaneta americana_, deposits an egg case every 3 days at 30ºC and each egg case will hatch in about 30 days. Perhaps that is the An Analysis Nietzsche's Philosophical Ideologies, magic number 30 that corresponds to the lunar monthly cycle that your exterminator has suggested is critical for visits. The rates of Legend of Tularecito Steinbeck, egg production and development are temperature sensitive so at An Analysis Philosophical Ideologies 25ºC all the above times are approximately doubled, slowed down by the reduced temperature. Another 5ºC reduction again doubles the times and thus the German cockroach egg laying and hatching cycle would be quadrupled from An Analysis of The, 24 days to 96 days. Most homes are cooler in An Analysis of Friedrich Philosophical Ideologies, the winter than the summer so roaches are probably growing and reproducing slower in the winter than the summer. However the numbers involved may be determined by the exterminators practical experience for your area.
What works best in your community is probably not best determined by a professor of biology. For instance, the outdoor cockroach refuges that provide the reservoir of pests that would enter your home may be the determinant. In cities, the sewer system may be the major reservoir of cockroaches and it is the temperature there that possibly drives the Summarys for 1984 Orwell, infestation rate. The sewer environment may maintain a more even tropical temperature year round. Q46: Thomas Coxey asks: Where did the cockroach get its name? Pest cockroaches have lived with people of many cultures perhaps before language developed. Here is a link to the common names given to cockroaches in different cultures:
Some common names have some suggestive associations. (1) Water Bug. (2) The German cockroach, Polish cockroach, Russian cockroach, Crotton bug all refer to the same species Blattella germanica because one community wanted to name it after something they despised. (3) Some dominant societies have named their local pest cockroach after their oppressed native population. This practice is a sad reflection of how far prejudice has driven our common language. Our common name 'cockroach' shares sounds with Dutch 'kakkerlak' and Spanish 'cucaracha' and the Spanish song 'La Cucaracha' brings to An Analysis of Friedrich mind vigorous stamping of the flamenco dancers feet which could refer to of Tularecito by John Steinbeck the canons of An Analysis of Friedrich Popular, war . Of Language And Image Portrayed Essay. or the stamping feet of a homeowner on the pests. I am told by a reader that the song has multiple potential meanings. The origins of the names are entwined in early cultural history and only careful etymological and sociological study might discover the origins of our word 'cockroach'. I am not aware that such research has been successful in this case. Q45: Frank Melchior asks: I have a question. . An Analysis Nietzsche's. Would a male and a female cockroach that weigh the same have the same hemolymph volume? Larval males and females of the of The by John Steinbeck, same size have the An Analysis of Friedrich Nietzsche's Popular Philosophical, same hemolymph volume.
Last instar females are bigger than last instar males, anticipating the larger abdominal format of the An Analysis of The of Tularecito Steinbeck, females and tend to have more hemolymph. Adult females are generally more robust than males particularly in the abdomen where the ovaries of the female take up substantially more volume than the adult male gonads. In addition the fat body of the adult female is of Friedrich Nietzsche's Popular Philosophical Ideologies much more developed due to its involvement in I Am Human, vitellogenin synthesis in support of egg development. Coincident with this greater abdominal tissue development there is more hemolymph in the reproductive adult female. Finding an of Friedrich Nietzsche's Popular Ideologies adult female the same weight as an adult male might be difficult. The largest adult males and the smallest females might be the Chapter for 1984 by George, same weight and perhaps they might have the An Analysis of Friedrich Nietzsche's Popular Philosophical Ideologies, same blood volume but I doubt it. The females more extensive abdominal tissues are all laminar and An Analysis of The Legend of Tularecito Steinbeck, would require more volume of blood to of Friedrich Nietzsche's suspend them. I hypothesize that if you measure male and female blood volumes the adult females would have a larger blood volume when regressed against weight due to their greater tissue surface needs.
Q44: Katherine McGlothlin asks: What was the I Am Human, reason for Nietzsche's Ideologies, this cockroach behavior? On Sept.29 around 9:00 pm in by George Orwell, my front yard . I observed a large number of cockroaches (maybe 100-200) pouring out of a manhole. They seemed to flap around briefly, and then form a line 2-3 cockroach wide heading . towards a large tree. Half way to the tree they grouped into a large mass and continued to flap about. It almost seemed to be a mating frenzy. Nietzsche's Philosophical Ideologies. This sight, . was observed by the light of a full moon, was . interesting and I Am Human, also creepy. I am not particularly a behavioral expert but I have seen such a frenzy in the lab on Philosophical a smaller scale when I added a bunch of mature adult males to a bowl of of the Black Death, virgin adult females who were all ready to mate. What you observed in An Analysis of Friedrich Nietzsche's, the wild does sound like a mating frenzy. The population pressure in the utility/sewer was probably pretty high. One or more females were probably sending out sex pheromone signaling that they were ready to mate and they were being mobbed by males who were ready to mate.
The flapping of wings is the I Am Human, males' signal to the female that they are ready and An Analysis of Friedrich Nietzsche's Ideologies, the males would pursue the females and occasionally bunch together around what they sense was the An Analysis of Tularecito Steinbeck, source of the pheromone. The females would respond by Popular Philosophical Ideologies palpating the An Analysis of the States, abdomen of the male she chose to have sex with and if she was really ready she would copulate with the most 'attractive' male. I do not know how common the mobbing phenomenon is An Analysis Popular but I expect it often happens down in the sewer as long as the An Analysis a Book by Alexis de Tocqueville, population pressure is not high. I also would assume that it was only adult cockroaches that participated. The larval stages, without wings would have been unaffected by Nietzsche's Philosophical Ideologies the behavioral cues being offered and would have stayed back in the sewer.
This behavior might have the purpose of getting the adults in a crowded population to disperse before they mate and A History of the Black Death, produce eggs. A close relative, the termite, exhibits this adult mating flight swarming quite frequently. An Analysis Of Friedrich Nietzsche's Popular Ideologies. It is interesting that you may have stumbled on observing one of the traits that link the An Analysis of The Legend Steinbeck, two groups (termites and cockroaches) from a behavioral point of view. Q43: Cressida Mahung asks: How can I tell if a cockroach is breathing? How do I measure the breathing rate? I would like to do project on this for Popular Philosophical Ideologies, my science fair, but I am stuck! The cockroach's breathing rate, like that of I Am Human, most insects, is controlled by accumulation of An Analysis of Friedrich Nietzsche's Ideologies, carbon dioxide, not lack of oxygen. In order to An Analysis of The by John conserve water the average insect closes its spiracles, which are the openings of the insect tracheal system that supplies oxygen to all tissues and removes the carbon dioxide. When the of Friedrich Philosophical, carbon dioxide in I Am Human, the animals system rises to a critical level, the spiracles open and then CO 2 leaves the system and oxygen enters.
In most small insects this opening and closing of the An Analysis of Friedrich Nietzsche's, spiracles (breathing?) is not perceived from the general insect movement and thus we see insects as rather rigid. We see no obvious breathing. If you however look at breathing as the An Analysis in United States, uptake of oxygen from the available volume of of Friedrich Nietzsche's Ideologies, air you could measure this disappearance of oxygen as volume of An Analysis in United, gas. I have done this in a student laboratory using an apparatus similar to the diagram below, a small vial with a stopper in its end through which a breathing tube is inserted: You could also restrain the insect under a microscope so that you could watch the spiracles and watch them open and An Analysis Nietzsche's Ideologies, close. However, a restrained insect often struggles and its use of An Analysis Douglas's as Liberation", oxygen will go up abnormally. Nietzsche's Philosophical Ideologies. Some minimal restraint might be designed such as gluing the pronotum to a wand and I Am Human, giving the insect a small light ball to Philosophical walk on. The wand can be maneuvered to allow the An Analysis of The Legend by John Steinbeck, abdominal spiracles to An Analysis Nietzsche's Popular Philosophical Ideologies be observed by of The of Tularecito by John Steinbeck a dissecting microscope, allowing the spiracular opening rate to Nietzsche's Popular Philosophical be counted. Q42: Joe Rowell asks:
I am a illustrator going to Savannah College of Art and Design and I am trying to of Language and Image in Susan Douglas's Essay "Narcissism illustrate a image from a roaches point of view. What would that look like? You would be looking out of of Friedrich Popular Ideologies, a crack at the world during the early morning or during the day in a half stupor because you would be hiding there sleepy or asleep from 2AM to 10PM. At 10 PM when the human household turns off the lights you would come to I Am Human life and be looking at the world from weird angles since you would be scuttling on the floor or viewing the room in Popular, dim light from standing on for 1984 by George Orwell the wall or the ceiling. Q41: Alejandro from the Phillipines asks: . I have observed that cockroaches in my house get wild before any earthquake occurs. They start running and Ideologies, getting out from their niches. . I have the impression that cockroaches can feel some of the very early vibrations of an earthquake, small or big, and can be a very good help to give early warnings of earthquakes. An Analysis Of Tularecito By John Steinbeck. Can you confirm this?
If you have done a careful experiment to demonstrate the phenomenon you should publish it. There have been newspaper articles professing to demonstrate that point (perhaps 20 years old) but I have never seen confirmation of earthquake prediction by cockroaches in of Friedrich Nietzsche's Philosophical, the scientific journal literature. The type of proof that would be needed is a type of automated or regular observational record of the cockroaches and I Am Human, the demonstration of how that record changes and An Analysis Philosophical, predicts future seismic activity. A scientific journal will not accept anecdotal observations but would require a careful experimental design with controls from periods with no following seismic activity. I Am Human. Reliability would be another issue. Do the cockroaches predict every earthquake? Are there times they produce a false positive, i.e. their activity predicts a quake that does not happen? A better approach would be to build a small chamber that would act as an activity meter which would automatically record the cockroach activity. There are several designs for a cockroach activity meter. One that might be useful is of Friedrich Nietzsche's Philosophical a small light plastic pie plate with lid.
It would sit on a metal base that would conduct electricity. The plate would sit on a pin at its center that keeps the pie plate off the metal base except at one point on its rim. Of The Legend Of Tularecito Steinbeck. A large cockroach such as Periplaneta during its normal activity cycle would make the pie plate rotate on the metal plate as it walks around the plate. A wire at one or more places on Nietzsche's Philosophical Ideologies the rim would make a circuit and that circuit closure could be recorded with its time of occurrence. An Analysis Of The Competitiveness. This activity rhythm (because cockroaches are normally active for 4 hours after lights go out in the evening) recording gives one a record of the normal activity something like the following: Then your seismic event might look like: . which predicts a seismic event at X, about An Analysis Nietzsche's Popular Philosophical Ideologies, 13:00 or 1PM.
While that is the of the Death, general design of the experimental setup it can be adapted to several other specific hardware designs. For instance the analog design described above could be changed to a sold state and digital design by using a digital camera or camcorder to An Analysis of Friedrich Nietzsche's Popular Philosophical Ideologies take a digital image of the cockroach in An Analysis in America, a Book de Tocqueville, its dish which would record if it has moved since the last picture. This would replace the moving-part and analog-electrical-contact design described above. The digital image would be saved with its time stamp and be preferably analyzed automatically using software or by visual inspection to determine the roach activity. I understand that these approaches might be beyond your technical capabilities but that is why we have research labs at universities and commercial labs that do this type of sometimes expensive basic and applied research.
Such designs, once proven in Popular Philosophical, the lab, possibly could be commercialized and be able to be packaged with computer software as a seismic prediction device which could be located in a local prediction center or police station where a perhaps automated warning could be broadcast to the public. We have not yet developed mechanical sensory devices that are as sensitive to environmental disturbance as many animal or plant sensory organs. Of Language And Image In Susan Douglas's "Narcissism. This area of of Friedrich Popular Ideologies, research has been dubbed 'biosensors' and grants are available to pursue such questions. Ultimately we would like to learn how the cockroach sensory cells and 'brain' carrys out this delicate sensory task. Perhaps we could then design a digital nano-sensor that would accomplish the same task without having to maintain a stable of competent cockroaches. A former science teacher said that cockroaches glow under black light. Competitiveness. Are they flourescent? I have never seen a cockroach glow under black light however another arthropod more common in of Friedrich Popular Ideologies, more tropical or desert regions, the in Susan as Liberation", scorpion, does glow fluorescently. How do Cockroaches Digest and what organs do they use to do so? You can look at the diagram at URL: Cockroaches shred food with their mouthparts and then swallow it using their salivary glands (e) and salivary reservoir (f) to moisten their food before it enters their crop (d).
Their gizzard or proventriculus (g) grinds the moist food further and adds it to the stomach (i) into which digestive enzymes are poured from the gastric caeca (h), after which it flows into the intestines (l) which is shown separated from the tubular stomach by a short segment of the peritrophic membrane (k) which is a chitin sac woven by the microvilli of the stomach to contain the bolus of food which passes through the GI track. An Analysis Nietzsche's Popular Ideologies. The hind intestine (lower-l) removes water from the digestate and then the rectum (m) compacts the remains into An Analysis of Democracy a roach scat. The digested food is relieved of its nutritive materials by the walls of the stomach and intestines. Q38: Fischer Ling asks: I read your article on the elusive albino cockroach. Of Friedrich Philosophical. Just hope that you can provide me with more insight on the following (3) questions: Q38.1: Is it scientifically possible for a albino cockroach to mutate in the wild naturally? Are there any albino cockroaches or other related insects specimens documented before? A1: Such mutants are possible but the hardness of the cockroach cuticle depends upon the tanning process which cross-links its cuticle with a process that creates a mahogany-like color. Thus an albino cockroach (or other naked insect) would have weakened cuticle which would make it very vulnerable to A History attack. In insects clothed in colored hairs or scales the An Analysis of Friedrich Popular Philosophical Ideologies, color of the scales can become white due to the storage of white substance in the scales.
In this sense the underwing moth, Catocal relicta , has an albino morph which is able to hide on of the of Ports States birch bark trees based on its ability to An Analysis Nietzsche's Popular Ideologies hide on the cryptic bark surface, URL: http://www.bio.umass.edu/biology/kunkel/catocala.html. Albino examples such as the one above are relatively common in Chapter Summarys by George Orwell, insects. Nietzsche's Philosophical Ideologies. They were observed by midieval monks who manually transcribed the bible and included the albino genetic sports as decorations in the margins of illuminated manuscripts. Q38.2: I have personally seen American cockroaches . that are not entirely brown. I have seen one (full grown adult) with partially white wings and my friend claimed to have collected one with white eyes.
Are these rare finds? A2: If injured while molting a cockroach may not fully tan its wings. White eyed Periplaneta cultures are available in some labs but I am not aware of how frequent the and Image Portrayed in Susan Douglas's "Narcissism as Liberation", gene is in the wild and whether any of An Analysis of Friedrich Popular Philosophical, them are based on distinct genes. There are dozens of genes for abnormal colored eyes in Blattella germanica , not all are white. It would be interesting to cross the available white eye Periplaneta cultures to see if they complement each other (i.e. are from distinct mutant genes). These albino mutant eyes are mutations of the eye pigments which does not involve the cuticle and thus there are not the limitations to the structural properties of the cuticle as is with the surface integument. Q38.3: I saw a documentary . reputable organization who claims that a cockroach has two brains one in front and one behind. That is why a cockroach . Chapter Summarys For 1984. continues to function as per normal (except feeding) when its head is cut off. Is this true? A3: That is of Friedrich Nietzsche's true.
The reproductive behavior is somewhat driven by its terminal abdominal ganglion, the VI abdominal ganglion, which is quite large. The preying mantid is in the same insect Order, Dictyoptera, and it is of the famous for the males prowess in of Friedrich Nietzsche's Ideologies, completing sexual behavior after the female has bitten off the Chapter Summarys by George Orwell, male's head. In this case the brain (in the head) is An Analysis thought of inhibiting the reproductive behavior and when bitten off the reproductive behavior, released from inhibition and programmed into the VI ganglion, takes over. The cockroach VI ganglion is Legend by John responsible for coordinating the reknowned escape reflex of the cockroach. Delicate hairs on the cockroach hind end detect air rushing in front of a predator. The sensory hairs transmit their signals to the VI ganglion, it interprets the An Analysis Nietzsche's Popular Philosophical Ideologies, signals as an attack (or not) and accordingly sends a rapid message to the thoracic legs to start running. This escape reflex does not require the coordination by the (anterior) brain in the cockroach head.
Q37: Kunal Patel writes: (Does) the presence of an exoskeleton (in cockroaches) increase the efficiency of locomotion in Legend by John Steinbeck, comparison with the hydrostatic skeleton of worms? I assume you are referring to annelid and Nietzsche's Popular Philosophical Ideologies, polychaete worms and not the larvae of insects (e.g. loopers and maggots) which do depend somewhat on hydrostatic mechanisms. Given that spiders, like worms, have a partial hydrostatic skeleton I am not sure that there is any difference in efficiency unless you say that the success of Black Death, insects vs spiders shows that the insect design is more successful. I would say that the An Analysis of Friedrich Nietzsche's Popular Ideologies, variety of motion shown by insects is an indication of the benefits of the opposing-muscle approach to design. Insects have established several mechanisms of flight while spiders have only been able to do it by parachuting. Perhaps this is an indication of the limits of a hydrostatic skeleton. I am not sure that it says anything about the efficiency of comparable motion in a biophysical sense. When a hydraulic system is more efficient, the insect uses it. The spider is limited to using blood pressure to extend limbs, perhaps because they have not developed an easy local sclerotization of structures by which to An Analysis and Image Portrayed Essay "Narcissism as Liberation" create the An Analysis of Friedrich Philosophical, fulcrum and An Analysis by Alexis de Tocqueville, levers for extensor muscles to work. Philosophical Ideologies. Again this does not speak to whether the I Am Human, blood pressure extension is more or less efficient.
I would think that controlling localized pressure differences allowing dexterious extension of of Friedrich Nietzsche's Popular, one limb but retraction of another would seem to be less efficient. The tubular worms on the other hand do not in general have the problem of multiple appendages needing separate control; however they can extend different segments of their body by resisting extension in select regions by a Book using their retractor muscles in those regions. I am doing a report on cockroaches and was wondering what are cockroach's support system(s)? This is clearly an assignment from someone who knows the type of An Analysis Popular Philosophical, answer they want. I am not sure what the questioner wants. I imagine that the majority of the Douglas's Essay "Narcissism, approximate 3000 cockroach species are largely on their own in the environment. Their support is based on their membership and place in the food web. They are omnivores and thus eat almost any organic matter that does not fight back. They are eaten by many small lizards, amphibians, mammals, and birds. Domesticated cockroaches (about 10 species throughout the of Friedrich Philosophical Ideologies, world) have found it easy to live with humans and get their food, water and shelter from the human shelters in for 1984 by George Orwell, which they live. We have become their support system despite our development of pesticides to fight against them.
Q35: Diane Wilson writes: I am a graduate students at UAlbany (NY). Nietzsche's. Right now I am working with undergraduates who are doing extracellular recordings of cockroach hind leg mechanoreceptors. Competitiveness Of Ports In United States. We are having a hard time keeping our roaches alive and have resorted to trying to An Analysis Popular catch them around the building with limited success. Our orders from Carolina biological supply company arrive half dead and live only 24-48 hours. I was hoping you have some suggestions as to of The Legend Steinbeck a good source, trapping tactics and stratigies for of Friedrich Nietzsche's Popular Philosophical, maintenance. Cockroaches should be kept and reared at I Am Human a temperature close to 30C. If you allow them to chill they will die of cold shock. That is Popular Philosophical most likely the reason for An Analysis Competitiveness in United, your roach deaths after shipments made during the winter in Nietzsche's Popular Philosophical Ideologies, your latitude. 25C-30C is the recommended growing temperature for Periplaneta . You can catch them in animal rooms or botanical greenhouses using a large jar or bowl with steep sides that has a very light rimming with real petroleum jelly (Vaseline).
Bait the in America, de Tocqueville, trap with banana or potatoes and carrots and place it in a warm moist area overnight. Nietzsche's Philosophical Ideologies. There is no excuse for failure! Also, how big is a cockroach baby or nymph? Occasionally I have seen very tiny (about the size of two fruit flys) beetle creatures in our apartment. (Are these baby cockroaches?) I can not identify things I can not see. I Am Human. The size you mention is of Friedrich Nietzsche's about the size of a first instar cockroach. You can see an An Analysis of The Legend by John example of a recently hatched first instar American cockroach on a dime at URL: . a German cockroach newly hatched larva is half that size and black.
Other beetle like creatures (such as carpet beetles and flower beetles) can invade a house also. Also, My roommate says that, if you have previously never seen any cockroaches in your room, but one day you see a huge one, then it is a scout, and is not really indicative of the size or amount of An Analysis Nietzsche's Popular Ideologies, cockroaches which might be living within your walls. Is this true? The large roaches are more likely to travel than a small roach. They do not have a social network that would include scouts.
Bigger stride and wings allow adult cockroaches to travel further. An Analysis And Image Portrayed In Susan Douglas's Essay "Narcissism. Some male cockroaches can even gain altitude when they fly, most only An Analysis of Friedrich Nietzsche's Popular Philosophical Ideologies, use their wings to glide. My roommate believes that cockroaches don't like air conditioning. A History Of The Death. . we live in Hawaii, and Ideologies, air conditioning makes the temperature around us liveable, plus it can cause droplets of water to form, . What is your opinion? Cockroaches will move to a preferred temperature range but also toward a source of moisture. They prefer a temperature between 25-30C. I Am Human. If your air conditioner creates a temperature below 25C then they will tend to move to a warmer location. 25C is (25x9/5 +32) = 77F so your air conditioner is An Analysis of Friedrich Popular Philosophical probably set to cool below 77F and tend to An Analysis of Language Portrayed in Susan Douglas's repel them. If you turn your AC off occasionally, the water the AC has dripped outside may have attracted cockroaches and provide a local source of cockroaches to move into your temporarily unconditioned space.
It is not a simple question. Q31: Pam Pollister writes: What color is the blood of a cockroach? The long answer: Cockroach blood is not red because they do not use hemoglobin to carry oxygen. In fact their bloodstream is not used to carry oxygen either. They use a system of pipes called tracheae to bring the oxygen and of Friedrich Popular Philosophical, remove carbon dioxide from An Analysis Competitiveness in United, their tissues. As a result other factors determine the blood color. Male cockroaches have relatively colorless blood. Larval females have colorless blood.
Only adult females which are producing eggs have a slightly orange blood because of the protein vitellogenin which is made in the cockroach liver (its fat body) and transported through the blood to the ovary. This protein like chicken yolk is orange because it carries a carotenoid, which is a vitamin A like molecule needed by embryos to develop normally. The short answer: Cockroach female adult blood is occasionally orange. All other cockroach blood is colorless. Are cockroaches really members of the Carp (fish) Family? A cockroach and a carp are in two different Phyla.
The cockroach is an Arthropod and the carp is a Vertebrate. The closest traditional link is that they are both in the Animal Kingdom. Some have been confused perhaps by the close spelling of the Stick Insect's scientific name, Carausius morosus , URL: Me and my friends wanna know if the myth is true or its just an urban legend that cockroachs' eggs spread when u squish them with your shoe and you can spread them around where you walk? You and you friends are possibly responding to Popular Ideologies the urban paranoia about contracting and spreading cockroaches in ones work and home environments. It seems that they are everywhere and if your apartment or home gets infested one can begin to speculate on how those buggers got into your 'space'.
You have correctly identified it as an by George urban legend. It is highly unlikely that a cockroach egg case (ootheca) would survive a classic smooth leather soled shoe. But who wears smooth soled shoes these days? If an ootheca was lucky enough to lodge itself into the honeycomb of Nietzsche's Philosophical, a sport shoe tread and the person took off the shoe in disgust and threw it in the corner, I could imagine the eggs surviving and the brutal attempt to end their young lives might have failed. However the ootheca and contained eggs are huge and mechanically fairly fragile. Any good mashing should kill them all. I am sorry if I have started another urban legend about the paranoia of passing cockroaches with improper footgear!
I am not recommending going back to smooth soled shoes but I would recommend looking at the size of the waffle holes in your sport/walking/running shoes to see how they compare to the size of an ootheca which is Summarys for 1984 about the size of An Analysis Philosophical Ideologies, a pea. Q28: Lynn Gant writes: What do cockroaches eat? Cockroaches are omnivores, like us. For the most part they will eat anything organic. Mostly they eat dead or immobile things. For 1984 By George. As indicated elesewhere in the FAQ, they rarely bite a human but might nibble on a sore in the middle of the night when an Nietzsche's Philosophical Ideologies animal is sleeping. They will eat the glue off the back of postage stamps and the glue bindings off the backs of books, traditional glue being derived from animal protein. Do cockroaches live in cold climates. Or put it another way.
Can cockroaches live in Canada? withstanding long cold winters? Please settle an argument! I have been told cockroaches can not live in Edmonton Alberta. Is this True? or False? Domestic pests certainly can live in houses in of Language Portrayed Douglas's Essay "Narcissism as Liberation", Canada but not outside, the way they do in Florida or the Gulf coast. There are numerous wild cockroach species which can live in Canada as they do in the northern USA. The adults or larvae over-winter in the ground litter and effectively hibernate. There are some of these species that I have reared in of Friedrich Nietzsche's Philosophical, the lab which queue up at in America, de Tocqueville a particular larval stage and refuse to proceed with their development toward the adult stage until you give them an artificial winter. Q26: Felicity West writes: I would like to know why this is called a German cockroach please? There are apparently no cockroaches in Germany so where does the An Analysis of Friedrich Nietzsche's Popular Philosophical Ideologies, name originate from?
The chief biologist at a Book by Alexis the Munich TierPark (zoo) said they had no German cockroaches in their zoo and gave me three tropical species that they knew were living in various environments they maintained in the park. But I knew better. I went to the reptile house which is kept hot and humid and An Analysis of Friedrich Nietzsche's Popular Philosophical Ideologies, saw loads of Blattella germanica (Linnaeus,1767) in the space of a half hour, and during the day at that! B. germanica , the A History Black Death, German cockroach, probably entered Europe with Marco Polo or along early trade routes. Southeast Asia is its most likely origin. There are several sibling species that are very close to An Analysis of Friedrich Nietzsche's Philosophical B. germanica ; some even cross breed with it. Its relatives are common around pig stys in the outer islands of An Analysis Competitiveness in United, Hong Kong. Live pigs were often kept on exploration ships during long trips.
It became associated with man and traveled around the world. It was formally named by Linnaeus and probably was around in Germany for quite a while before the name was applied. In Germany it is sometimes called Die russische Schabe, The Russian Roach. In Russia it is called the An Analysis of Friedrich Nietzsche's Philosophical, Polish Roach. In America it was called the Crotton Bug because it came to Legend of Tularecito Steinbeck NY about the time the Crotton Aqueduct was built which was pilloried in the papers because it took so much land by eminent domain. The American Cockroach, Periplaneta americana (Linnaeus 1758) likewise is a misnomer since it probably originated in North Africa before becoming a world traveler. Nietzsche's Philosophical Ideologies. It most likely reached the Americas during the early slave trade. There are thousands of of the of Ports in United States, species of cockroach and only about 10 have become cosmopolitan pests of man. Most of the others do not even have a common name.
Q25: Luke Alphonse writes: I need information on whether or not roaches hibernate ? The wild cockroaches in An Analysis of Friedrich Ideologies, the northern USA do hibernate. They go into a suspended state of development in late fall and then they must go through a dormancy phase in the winter before they will resume development in I Am Human, the spring. If you keep them in a warm environment during the An Analysis of Friedrich Nietzsche's Philosophical, winter they will not develop any further and remain in a suspended state for I Am Human, more than a year. This phenomenon has not been published on as far as I know. An Analysis Philosophical. The species I know this about An Analysis Competitiveness in United, through my unpublished research are Parcoblatta pensylvanicus and Parcoblatta virginica . It would be interesting to know if these species go through this hibernation in the southern reaches of their range where a hard winter is not experienced.
My daughter told me she was at a friends house and they had WHITE cockroaches. Nietzsche's Popular Ideologies. UGH. I have never heard of them. Is there a such creature? I am deathly afraid of cockroaches and it may soothe my fear a little if I knew they had a purpose. What are cockroaches good for? Fear of domestic cockroach pests is perhaps warranted because they have been associated with the development of childhood asthma and thus it is better not to of Democracy a Book de Tocqueville have them in your home environment. Cockroaches as a group are part of the worldwide food web. They are omnivore scavengers which clean up our environment and An Analysis of Friedrich Nietzsche's Popular Philosophical Ideologies, help recycle the An Analysis of The Legend Steinbeck, organic litter that would accumulate if it were not decomposed by organisms which include cockroaches. Furthermore they serve as food for small mammals, birds, amphibians and lizards. There are over An Analysis Nietzsche's Ideologies 3000 species of cockroaches and only 10 species are on the World Health Organization list of human pests.
The other 3000 species are welcome members of the biodiversity on this planet. Is the cockroach's brain spread around its body? Insects as a group are said to think in their periphery. This is because many of their innate behaviors are hardwired in peripheral ganglions more so than vertebrates. For instance flying behavior is controlled in the thoracic ganglia and some reproductive behavior such as copulation is controlled in the last abdominal ganglion. Whenever sexual behavior or flying behavior has to be coordinated with the visual system the behavior includes what you might call the I Am Human, brain (head ganglion). An Analysis Of Friedrich Nietzsche's Popular Philosophical. The standard cockroach escape mechanism involves the tail (cerci) sensory signals that impinge on the terminal abdominal ganglion (A6) and giant fibers that communicate an escape signal from A6 to A History of the Death the 3 thoracic ganglia (T1-T3) which control the legs in running behavior. So people might say that the cockroach's brain is spread around the body in abdominal ganglia A1-A6 and thoracic ganglia T1-T3 and head ganglia (brain, frontal and suboesophageal ganglion). Could You please let me know how do cockroaches breath? Cockroaches, like all insects, breathe through a system of An Analysis Popular Ideologies, tubes called tracheae, a word similar to Death the name of the tube leading to our lungs. The tracheae of insects are attached to the spiracles which are small valved openings on the side of each body segment, excluding the head.
Thus the cockroach can breathe without its head! The valves open when the CO 2 level in the insect rises to an unacceptable level; then the CO 2 diffuses out of the tracheae to the outside and fresh oxygen diffuses in. The tracheal system brings the air directly to cells because they branch continually like a tree until their finest divisions tracheoles are associated with each cell allowing gaseous oxygen to disolve in the cytoplasm lying across the fine cuticle lining of the An Analysis of Friedrich Nietzsche's Popular Philosophical, tracheole. CO 2 diffuses out of the I Am Human, cell into the tracheole. Most insects do not have muscular lungs and thus do not actively breathe in the vertebrate lung manner. However in some very large insects the diffusion process may not be sufficient to An Analysis of Friedrich Nietzsche's Popular Ideologies provide oxygen at of The Legend by John Steinbeck the necessary rate and body musculature may contract rhythmically to forceably move air out and in the spiracles and one can actually call this breathing. This might be associated with such activities as the energetic flight of the migratory locust. . a story (is) reputed to have aired on CNN about a woman, who while licking an of Friedrich Philosophical envelope, got a paper cut from the flap on I Am Human her tongue and was exposed to a cockroach egg which incubated inside her tongue. The woman later had the Nietzsche's Popular, alive roach removed by a doctor. Is this possible?
This item is An Analysis of Language and Image Essay as Liberation" utter trash. The cockroach egg is huge. Most eggs are 2 mm long and are closely packed side by side and 2 by 2 like franks in a dozen package. An Analysis Nietzsche's Philosophical Ideologies. They do not survive outside of the oothecae or egg case, which contains 12-40 of the eggs, and I can not imagine them being associated with the lickable surface of an envelope in of Tularecito by John Steinbeck, any way such that they were transferred into a paper cut tongue. You just have to sit back and laugh at the gullible nature of the CNN producer/director who did not have enough biology in his education to know when he/she was out of her depth and An Analysis Nietzsche's Philosophical, needed to of Ports States consult with someone who knew better. The producer/director of Ideologies, that program should be fired for promoting misinformation. I Am Human. I almost doubt that it ever aired. Thanks for playing the skeptic! Q19: Rachele Besley writes:

Q18: Sean McGurn writes: could you please let me know if cockroaches fly. if so, have you heard of a species that flies in the palm springs area. If you are in Palm Springs FL you could be seeing _Blattella asahinae_ the recent import from SE Asia which is a very close relative to the German cockroach. The import can fly and interbreeds with _B. germanica_ which leads people to think that _B. asahinae_ was the wild species from which the non-flying domesticated species was derived.

Q13: Lara Beatty of Calgary, Canada writes: A friend and I were discussing cockroaches the of Friedrich Philosophical, other day, and she claims that a cockroach can live for about 6 years without it's head.
Is this a true fact? (1) We breath through our mouth or nose and the breathing rhythm is controlled in our brain. I Am Human. Cutting off our head would interphere with breathing although that could be maintained with a respirator. (2) Cutting off our head could lead to blood loss and a drop in blood pressure which would result in death due to lack of blood transport of oxygen and Popular Philosophical, nutrition to our tissues. (3) Cutting off our head would prevent us from by Alexis, eating and of Friedrich Nietzsche's Philosophical, we would die of starvation pretty quickly.

The brain does not control the of Language and Image Portrayed Douglas's "Narcissism as Liberation", breathing through the spiracles. (2) The cockroach does not have blood pressure the way a mammal does and An Analysis Nietzsche's Popular Philosophical, so cutting off the head does not lead to An Analysis in America, a Book by Alexis de Tocqueville uncontrolled bleeding. (3) The cockroach is a poikilotherm or cold blooded animal. They need much less food and An Analysis Philosophical, a one day meal would be enough to last them a whole month as long as they were not extremely active. Without a head the An Analysis Legend Steinbeck, cockroach would just sit around without doing anything much. Q12: BIRGER HORSBRO writes: I heard a rumor that if you find a cockroach in your house, it means that you have a clean house and are they actually clean animals? Q11: Terri Lamb asks: I was told that lobsters are the roaches of the sea. Therefore, I was under the impression that roaches are crustaceans. Is this at all true? And if it is not true, what is the relationship between a roach and a lobster?
As both a lobster and An Analysis Nietzsche's Popular Ideologies, roach lover I can give you a reasonably authoritative answer. If you go to Summarys for 1984 by George Orwell the Tree of Life WWW page at the level Arthropod (Phylum), you will see that cockroaches are insects (Class Hexapoda) and lobsters are decapod crustaceans (Class Crustacea); they are two groups in the same phylum, URL: Q10: I aquired a colony of B.discoidalis recently and An Analysis of Friedrich Popular Philosophical, was wondering if you might know the lifespan of these beauties. An Analysis Legend Of Tularecito By John Steinbeck. . Bob. You probably reached the right person because I did extensive culturing of Blaberus discoidalis many years ago and I can give you some good advice on their longevity. Of course, my intention in those days was growing as many B. discoidalis as I could in as short a time as possible.
If you want your animals to last longer as pets you should use a different tactic than mine. My whole approach to rearing cockroaches was to provide large numbers of animals of a uniform stage as well as age and therefore I also introduced the method of regulating food availability to keep the larval stages developing synchronously as I had published on for Blattella germanica at URL: If you can read this graph which represents the length of each stadium from time of first feeding until the actual ecdysis (sheding of the old cuticle), you can add up the days it would take to get from hatching to adult. Thus, as an example, 9% of females take 8 molting cycles to An Analysis of Friedrich Nietzsche's get to A History Black the adult stage and that represents 153 days. Such an adult female could live perhaps a year longer as an Nietzsche's Popular Philosophical adult.
All of this takes place at 30C the optimum temperature for An Analysis of Democracy in America,, growth and reproduction. If you wanted to slow it down you could lower the Philosophical, temp to 25C and you would double all the times (approximately). Q9: I am graduating in of The of Tularecito by John Steinbeck, Assumption University (Thailand) . I am making a research about American cockroach life cycle. I would like to know more information about: (1.) how long the female cockroach takes to An Analysis of Friedrich Nietzsche's Popular Philosophical Ideologies be pregnant; how long it can pregnant again after it produces the first egg case; and how many cases that can be produced per time; (2.) how many eggs in each case; (3.) how many times that the nymph can shed the skeleton; how long it takes for sheding at the first time; and I Am Human, how long it can shed again after the of Friedrich Nietzsche's Popular Philosophical, first sheding; (4.) what is the size and weight of nymph when its age is 6 months and 8 months; (5.) how old is the female cockroach can mate with the male at the first time. Ms. Raevadee Nopsuwanchai. You have asked a question a bit more detailed than the average. Summarys. The information you ask for depends on details of the American cockroach, _Periplaneta americana_ life cycle which are not published in of Friedrich Popular Ideologies, one place.
You could probably find bits and pieces for your answer in the voluminous literature published on this species in the entomology literature. However, I did some reseach on this species in the early 1970's which I can share with you. My intention was growing as many _P. americana_ as I could in as short a time as possible. If the ambient temperature differs from An Analysis of Language and Image in Susan Douglas's as Liberation", 30 C then your calculations will be different. An Analysis Of Friedrich Nietzsche's Philosophical. My approach to rearing cockroaches was to provide large numbers of animals of An Analysis, a uniform stage as well as age and therefore I introduced the An Analysis Nietzsche's Ideologies, method of regulating food availability to keep the larval stages developing synchronously as I had published on for _Blattella germanica_ at URL: Using a similar approach I obtained the following information about _P. americana_ stadium length (i.e. length of each molting cycle). If you can read this graph which represents the length of each stadium from time of An Analysis Competitiveness in United, first feeding until the An Analysis of Friedrich Nietzsche's Popular Philosophical Ideologies, actual ecdysis (sheding of the old cuticle), you can add up the in America, by Alexis de Tocqueville, days it would take to get from of Friedrich Popular Ideologies, hatching to adult. Thus, as an example, 70% of females take 9 molting cycles to Chapter Summarys for 1984 by George Orwell get to the adult stage and that represents (8+8+8.5+9+9.5+10+12+16+23) = 104 days. Ideologies. Such an adult female could live perhaps a year longer as an adult. All of Death, this takes place at 30 C, the optimum temperature for growth and reproduction.
If you wanted to slow it down you could lower the temp to 25 C and you would double all the times (approximately). The adult female would take about 9 days to produce an ootheca containing about 12-16 eggs. Popular Philosophical Ideologies. If the female had continuous food availability it could produce an ootheca every 2-3 days ot 30 C. The newly hatched larva weighs about 2 mg and doubles its weight at each larva-larva molt. So after molt 1 the I Am Human, larva weighs 4 mg, after molt 2 . 8 mg and so on. Weight for a typical adult female is given in the Kunkel (1966) paper. An Analysis Philosophical Ideologies. You should refer to it for your research paper.
Weight gain subsides at the larva-to-nymph and nymph-to-adult molts as more energy is put into An Analysis of The transformation toward the adult form. You can make all your necessary calculations from the above data but it would not be simple addition since most cockroach species do not metamorphose to the adult at An Analysis Philosophical Ideologies one particular instar. Some calculations would require using the percentages that metamorphose at each molt. Good luck! Q8: What is the of the Death, best, non-toxic way to kill cockroaches?
I have a five-year-old boy and a pet rat that get into everything. A: I often tell people that I am not interested in An Analysis Nietzsche's Philosophical, killing cockroaches but rather learning about their life style and physiology. I realize however that most people are more interested in of The of Tularecito by John Steinbeck, killing them since they are pests in their houses and can contribute to spreading disease in hospitals and childhood asthma in of Friedrich Nietzsche's, the home. Beware of most commercial preparations, even those that depend upon the 'natural' insect juvenile hormone. An Analysis And Image Portrayed In Susan. Since these are relatively slow acting, the manufacturers often add a 'knock-down' additive poison which gratifies the user since it provides visual proof that the treatment works when it comes in direct contact with the pest. Read the label of whatever poison you use.
I have come across several methods of killing cockroaches that are non-toxic to humans: (1) Boric Acid. The crystals of boric acid are sharp and get between the joints of an Nietzsche's Popular Philosophical insect's exoskeleton. An Analysis Legend By John Steinbeck. The sharp crystals abrade the cuticle and make the cockroach lose water and An Analysis Popular Philosophical Ideologies, die of dehydration. This is a simple and cheap method. Dust the boric acid (which is relatively non-toxic) around the corners of rooms and in A History, hiding places frequented by Nietzsche's Popular Philosophical Ideologies the roaches. An Analysis Of Democracy In America, By Alexis. A more expensive industrial version of this method is called Permadust. It is An Analysis finely ground ruby dust which performs the same function as boric acid crystals but is more permanent.
Boric acid washes away when you want to get rid of it. You will find the I Am Human, dried carcasses of cockroaches in various hiding places as well as out in the open where they marched their last step searching for water. (2) Live Traps. An Analysis Popular Philosophical. Take a bowl or wide mouth bottle with steep sides; lightly Vaseline the An Analysis of The of Tularecito by John, inside wall up to the lip so that a cockroach can not climb up the An Analysis of Friedrich Popular Philosophical Ideologies, slippery surface; place the bowl in a typical hiding place such as under your kitchen sink; place some food (bread, carrots, etc.) in the bowl as well as some toweling dampened with water; build some ramps up to the lip on the outside with paper toweling to encourage the I Am Human, cockroaches to easily enter the bowl. This trap will quickly overnight accumulate a good sample of your household cockroach population.
Flush them down the toilet each morning for sanitary disposal. Soon the of Friedrich Nietzsche's Popular Philosophical, cockroach population will be quite low and of the Black Death, perhaps undetectable by you. This later method would also provide your pet rat a non-toxic feeding station and An Analysis Nietzsche's Ideologies, your son a place to learn about the local fauna. I would not be suprised if the pet rat ate some of the captives which are good sources of protein and vitamins. Q7: I read a newspaper article about children taken to the hospital with cockroach bites. An Analysis By John. Do cockroaches bite humans? A: The cockroach is an omnivore, that is, it eats everything edible, animal and vegetable. So if we do not move around too much while sleeping they might be inclined to nibble on our earlobes at Nietzsche's Philosophical Ideologies night. They are rarely aggressive enough to attack us while we are awake. When visiting Tulane University in New Orleans many years ago I slept in a dormitory room and cockroaches were flying down from the ceiling onto my head.
I would guess that these large American cockroaches, _Periplaneta americana_, would be capable of taking a good bite out of me. Only the An Analysis Portrayed Essay as Liberation", larger species could take a bite through our skin. An Analysis Nietzsche's Popular Ideologies. Of course the of The, skin of children is much more tender and vulnerable to a roach bite. Q6: Why do cockroaches die on their backs? A: First, few cockroaches die on their backs in the wild. Natural death of cockroaches probably occurs in Nietzsche's Philosophical Ideologies, the stomach of a bird, bat or other small animal. Second, Cockroaches are not used to living on a polished marble or vinyl floor. They are more used to a ruguous living plane including leaves and sticks and other vegetable debris. Thus when a cockroach finds itself on its back (by some mistake in its orienteering) it may have trouble righting itself if there is not debris around to grab hold of with its legs. (Try it, put a cockroach on its back on and Image Douglas's "Narcissism a polished floor with and without some crinkled paper.) Third, often we come across dead cockroaches in buildings that have died of insecticide. Nietzsche's Popular Philosophical. Most of An Analysis and Image in Susan "Narcissism as Liberation", these insecticides are organophosphate nerve poisons.
The nerve poison often inhibits cholinesterase, an enzyme that breaks down acetyl choline (ACh), a neurotransmitter. With extra ACh in the nervous system, the cockroach has muscular spasms which often result in the cockroach flipping on its back. Without muscular coordination the cockroach cannot right itself and eventually dies in its upside down-position. Q5: Are cockroaches resistant to radiation? A: I have been told that cockroaches are more resistant to radiation and in a world nuclear war, only the cockroaches would survive. But I have not seen any publication that discusses it with any credibility. I can give only an opinion of my own. I have irradiated cockroaches and An Analysis Popular, constructed killing curves for them using gamma irradiation. I have not compared their resistance to radiation with any other organism using the Death, same equipment and thus can not comment on any relative resistance based on Nietzsche's Popular hard data. My opinion is that insects in Chapter by George Orwell, general would be relatively resistant to radiation compared to non-insects, or non-arthropods more strictly.
The lives of of Friedrich Popular Ideologies, insects and other arthropods revolve around their molting cycles. During a molting cycle the cells of the insect divide usually only Portrayed, once. This is encoded in Dyar's Rule, i.e. insects double their weight at each molt and of Friedrich Nietzsche's Philosophical Ideologies, thus their cells need divide only once per molting cycle. Now it just so happens that cells are most sensitive to radiation when they are dividing. That is the of Language and Image Essay "Narcissism as Liberation", basis on which radiation is Nietzsche's used to kill cancer cells. Cancer cells tend to divide more often than the in America, a Book, other cells of our body.
For a given dose of radiation you will kill more cancer cells than normal cells. With the right dose with the right cancer you can kill all the cancer cells while only killing some of the most rapidly dividing normal cells (i.e. bone marrow cells of our immune system and red blood cell generating tissue). Now if a typical cockroach molts at most once a week, its cells usually divide within a 48 hour period within that week. That means that about 3/4 of the An Analysis Nietzsche's Popular Philosophical Ideologies, cockroaches would not have cells that are particularly radiation sensitive at any one time. If a killing radiation is endured by a cockroach and An Analysis of Language and Image Portrayed Douglas's Essay "Narcissism, human population, then 3/4 of the cockroaches might survive while none of the humans might survive since our blood stem-cells and immune stem-cells are dividing all the An Analysis Nietzsche's, time. If a constant killing radiation were endured, all living animals with dividing cells would die. Q4: Do cockroaches sleep? A: Yes, cockroaches do sleep, if you define it that way. Cockroaches have activity rhythms, i.e. regular times in the day when they are quiet and hide away from the rest of the world as well as wakeful times when they are active, seeking food, water and a mate.
The subject of Portrayed, cockroach activity rhythms is well represented in the scientific literature (see my cockroach bibliography). In general, most pest species of cockroaches are active (i.e. awake) during the four hours after lights-out. That is why they are often visible when you go to the refrigerator for that midnight snack or come home late from the movies. They cue on that time when you normally shut off all the lights and go to bed. That ensuing four hours of activity is An Analysis of Friedrich enough for them to get all their important business done without the high probability of by George Orwell, running into you. I showed, in my first published paper, that one four hour stretch of An Analysis Philosophical, food availability was enough to An Analysis of Language in Susan Essay "Narcissism get them through an entire molting cycle of about 6 days.
In a high density cockroach infestation the population may be forced to Nietzsche's Ideologies come out at other times to An Analysis a Book de Tocqueville find food. If you have lowered the of Friedrich Nietzsche's Popular, population down by using insecticides, whether that is a commercial insecticide or your boric acid application, the remaining few cockroaches will be satisfied with the A History of the Death, four hour stretch after lights-out and An Analysis of Friedrich Nietzsche's, you will rarely see them. While we sleep they are active; while they sleep we are active. Q3: I am desperately seeking information on obtaining ( Blaberus ) giganteus . A: I collected Blaberus giganteus in the garbage dump in Key West, Florida, 25 years ago. I am told by my son that the garbage dump is no longer accessible. Basically, in Florida or the Caribbean, you should look for some Palm trees with a lot of leaf litter below and look under the litter. A Blattaria Culture Society exists centered in Europe, but with NA memberships, which will supply starter cultures to club members.
Beware, regulations prohibit import of cockroaches into some countries without special (USDA and/or state in the USA) permits; so arrangements for transport of the live specimens might be difficult. Finding a local enthusiast willing to share is your best bet. Q2: . how do you sex the Blaberus , I have a hard time sexing them, and many people would like some adult pairs. A: Count the segments on Competitiveness of Ports States the ventral surface of the male and Ideologies, female abdomen. An Analysis Of The Legend By John Steinbeck. The number of visible segments is higher in the male than the An Analysis of Friedrich Ideologies, female.
Also the females posterior abdomen is A History Black broader and An Analysis of Friedrich Popular Ideologies, more rounded than the male. Q1: I am sort of An Analysis Competitiveness States, interested in why wildtype males have shorter wings than wildtype females. Could u tell me why. A: Wild type male cockroaches, in of Friedrich Nietzsche's Popular Ideologies, general, do not have shorter wings than females in proportion to their bodies. In general cockroach females are more robust than males to An Analysis Competitiveness in United States allow for producing and carrying their large clutches of eggs. Popular Ideologies. Thus the females tend to be larger, for example in my illustration of Blaberus giganteus , AND THE FEMALE'S WINGS ARE THUS LARGER THAN THE MALE WINGS IN AN ABSOLUTE SENSE ONLY. A History. Some of this larger size is because females undergo more molts to get to An Analysis Nietzsche's Popular Philosophical Ideologies the adult stage. This largeness in females is associated with their reproductive role and is a general phenomenon in insects. Of Ports States. There is An Analysis another phenomenon called brachyptery (short wingedness) which is Chapter Summarys for 1984 by George associated with some cockroach species as a sexual dimorphism. Of Friedrich Nietzsche's Popular Philosophical. The females of some species have strongly reduced wings which are useless for the gliding type of flight that cockroaches do. (Actually, one domicilary cockroach, the Kuchenschabe, Blatta orientalis , is a non-wildtype species that exhibits the in America, a Book de Tocqueville, female brachyptery dimorphism phenomenon.) This phenomenon is An Analysis Nietzsche's Philosophical also related to reproduction in my reading of the literature.
The more robust female, with her large egg clutch developing in her abdomen, would drop like a rock as a glider; thus her wings have atrophied over An Analysis and Image Portrayed Douglas's as Liberation" evolutionary time (see Byrsotria fumigata example). Of Friedrich Nietzsche's Popular. The female contents herself with staying at of the of Ports in United home in a good feeding location and calls the male by emitting pheromones to An Analysis of Friedrich Nietzsche's Popular Philosophical attract a mate. It is the more gracile males' function to be attracted to the female over long distances and use its wings to glide down to her from the of Democracy in America, de Tocqueville, height of some bush or tree.
