However, cockroach exuvia have been proved to be a contributing factor to asthma and allergies, especially in young children. + + Species found in Davis include + The American Cockroach (''Periplaneta americana'') + + These are probably the largest of the cockroaches in Davis, outside of the ["Bohart Museum of Entomology"], and are distinguished by the distinctive splotch on it's pronotum, or "back". These roaches are also equipped with two pairs of leathery wings, which they rarely use, and three pairs of legs, which propel the roach at up to 3.4 miles per hour. This gives them, what is estimated by some, to be the fastest proportional landspeed of any organism, 50 body lengths each second. Although this species is called the American cockroach (or occasionally called the Palmetto bug), it is believed to have originated in Northern Africa, and traveled on ships (and other forms of human transport) around the world. They seem to prefer dark and moist environments, such as sewers. They are commonly bred and used in a similar fashion to lab rats. Such experiments tell us that not only can an American cockroach live a week without a head, but that they also apparently still maintain rudimentary learning skills without a head, thanks to the distribution of the nervous system throughout an insect's body. + + The German Cockroach (''Blatella germanica'') + + These, on the other end of the spectrum, are the smallest of the peridomestic cockroaches here in Davis, measuring in at only about 1/2 an inch in length. On their pronotum are a pair of parallel stripes. Like the American cockroach, they rarely fly and also prefer damp environments. Likewise, the common name is a misnomer, this species being believed to have originated somewhere in Africa as well. These are the cockroaches spotlighted in cockroach reproduction horror stories, since each female can produce, at highest estimate, 352 young in a single lifetime, higher than the maximum total young for other common peridomestic species. So if you see one little German roach, you can easily assume there are likely, many, many, many nearby. + + *The Oriental Cockroach (''Blatta orientalis'') + + These are the darker cockroaches which lack distinguishing marks on their pronoutum altogether. The females, interestingly enough, have only short stubs for wings, whereas the males have long wings. However, like the other species, they do not appear to take to the air. These cockroaches like moist places, and like the American cockroach, are fond of sewers. Also like the American cockroach, this species is believed to have originated in Africa. + + And lastly, according to a study by Cochran and Ross, German cockroaches can withstand radiation between 6000 and 9000 rads, about 6 times higher than the fatal dose for humans. Unfourtunately for the roaches though, modern nuclear weapons release radiation on several magnitudes greater than both our tolerances. If a nuclear apocalypse rolls around, we're all screwed.
