What is the American cockroach genome?
The American cockroach genome is the second-largest insect genome on record, after Locusta migratoria. Around 60% of its genome is composed of repeat elements. Around 90% of the genome can be found in other members of Blattodea. Genetically, the American cockroach is closer to two termite species, Zootermopsis nevadensis and Macrotermes natalensis, than it is to the German cockroach. The genome codes for a large number of chemoreceptor families, including 522 taste receptors and 154 olfactory receptors. The 522 taste receptors comprise the largest number found among insects for which genomes have been sequenced. About 329 of the taste receptors are involved in bitter taste perception. These traits, along with enlarged groups of genes relating to detoxification, the immune system, and growth and reproduction, are believed to be part of the reasons behind the cockroach's ability to adapt to human living spaces.

Distribution
Despite the name, none of the Periplaneta species is native to the Americas; P. americana was introduced to what is now the United States from Africa as early as 1625. They are now common in tropical climates because human activity has extended the insects' range of habitation, and are virtually cosmopolitan in distribution as a result of global commerce.
Habitat
American cockroaches generally live in moist areas but can survive in dry areas if they have access to water. They prefer high temperatures around 29 °C (84 °F) and do not tolerate low temperatures. These cockroaches are common in basements, crawl spaces, cracks and crevices of porches, foundations, and walkways adjacent to buildings. In residential areas outside the tropics, these cockroaches live in basements and sewers and may move outdoors into yards dur…
