http://www.bio.umass.edu/biology/kunkel/rolleston/plate_viii.html ... This is an illustration by GEORGE ROLLESTON published in 1870. 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).

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 the cockroach brain. It is fast enough to detect the air wave in front of a predator and allows the cockroach to scuttle away, avoiding capture.

Cockroaches are omnivores, like us. For the most part they will eat anything organic. Mostly they eat dead or immobile things. 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 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.

Some people would rather get one really big message every day or so, rather than a lot of separate messages. That's a digest. You can get your jcnews in digest form by going to the yahoogroups.com website, registering, and modifying your subscription to the group. Or you can email Linda to do it for you. If you would rather not get email or a digest, but would rather just drop in from time-to-time, you can now read jcnews on the web. More info on that will follow, or you can go to yahoogroups.

the time of death, OPO personnel will review your medical history and decide whether your organs are suitable for donation. Advances in transplantation and medicines have allowed more people than ever to become donors.

Organs and tissues from Donor Registry consented donors are only recovered for the purpose of the transplantation. Should information come to light after the recovery procedure to indicate that an organ or tissue is not suitable for transplantation, an effort will be made to place the organ or tissue in an approved research protocol.

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.

Cockroaches (and most other insects) have two light receptors, one sensitive in 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 light. They are active at night and if anything they might avoid light. However, if you have a patio that is lit you might be asking what type of light should you have in your patio lighting scheme.

Laurie, There is a pest cockroach, Periplaneta australasiae, which is common outdoors in the southern USA. It is 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 the warmth of greenhouses at all latitudes. It is also found in western Australia. I am not sure of the etymology of the common name, 'Australian cockroach'.

Cockroaches, like all insects, breathe through a system of tubes called tracheae, a word similar to 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 CO2 level in the insect rises to an unacceptable level; then the CO2 diffuses out of the tracheae to the outside and fresh oxygen diffuses in.

First, few cockroaches die on their backs in the wild. Natural death of cockroaches probably occurs in 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.

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 constructed killing curves for them using gamma irradiation.

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 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.

A DIGEST mode is available. Those using DIGEST mode receive a weekly bulk mailing (40 Kb) of recent posts to the list. The advantages are that you have all of the posts in one file. The disadvantages are that you receive the digest after much of the discussion has occurred. You can subscribe to the DIGEST by sending SET CRUST-L MAIL DIGEST as the message body to LISTPROC@VIMS.EDU.

The SCA Digest is the electronic mail version of the Rialto. One can subscribe and unsubscribe by sending email to SCA-Request@mc.lcs.mit.edu, requesting your addition to or deletion from the list. Expect this to take up to a week - the people running the Digest are volunteers with other work to do. If you read rec.org.sca, there is no need for you to subscribe to SCA-Request, as messages are gatewayed in both directions.

You may ask for back issues of any digests by writing to SCA-Request@mc.lcs.mit.edu and specifying the date(s)/number(s) of the issue you want mailed to you. That address is serviced by overworked humans so expect any request to take up to a week to process. Please be reasonable about the number of back issues you request. ("Everything up to now" is *not* reasonable :-) You can also check Stefan's Rialto Archive at http://www.florilegium.org by Stefan li Rous (stefan@florilegium.

an organ donor, you can donate parts of the body such as the kidneys, heart, liver, lungs, intestine and pancreas. As a tissue donor, you can donate corneas, skin, bone, bone marrow and heart valves.

A national allocation system ensures the fair distribution of organs in the United States. To learn more visit www.unos.org/policiesandbylaws2/policies/pdfs/policy_70.pdf. People eligible to receive organs are identified based upon many factors including blood type, length of time on waiting list, severity of illness, and other medical criteria. Race, gender, age, income, or celebrity status is not considered when determining who receives an organ transplant.

Buying and selling organs for the purpose of transplantation is illegal in the United States. Under the Uniform Anatomical Gift Act of 1984, human organs cannot be bought or sold, and violators are subject to fines and imprisonment. This strict regulation prevents any type of "black market" for organs in the United States.

Household cockroaches are very unpopular guests for humans. Their favourite habitats are wherever it is moist and warm, for instance kitchens. At night they become active and start searching for food. In this way they transmit germs, putrefying bacteria and fungus spores. After house dust mites cockroaches are the commonest cause of allergies to arthropods. Studies in America have found that up to thirty per cent of the US population is allergic to cockroaches.

Once you start using Active Roach Killer Bait, you will start to see dead roaches in 2 to 3 days. And in 1 to 2 weeks, all cockroaches and the nest will be eliminated completely. But do bear in mind that new cockroaches may enter from outside again from various sources. That's why it's important to continue to use Active Roach Killer Bait to kill new cockroaches as they enter so that no new cockroach infestation will occur.

These "vectors" have been shown to carry a variety of disease-causing organisms. Some of these organisms are the cause of Salmonellosis, Shigellosis, Leptrospirosis, and a variety of other food-borne illnesses. The problem with rodent bait in a food facility is that rodents may carry the poisonous bait in their mouths and drop the bait throughout the facility, contaminating food, food contact surfaces, and food related items.

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.

Yes. Active Roach Killer Bait can help you get rid of all types of cockroaches, German, American, Oriental, etc. You name it, Active will kill it. And it works all year round.

People always ask us where we get the organs and other detailed questions. Our answer to these type of questions is that we have a non-disclosure policy due to the confidentiality of donors.

I have never seen a cockroach glow under black light however other pests in more tropical or desert regions, the scorpions, do glow fluorescently. Scorpions are well known for this behavior. Their generally soft cuticle has fluorescent compounds. There is a famous picture on the cover of Science of a fluorescent scorpion. I once took a walk in the evening desert outside Albuquerque NM with a portable black light.

This is clearly an assignment from someone who knows the type of answer they want. I am not sure what the questioner wants. I imagine that the majority of the 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.
