Cockroaches are a paraphyletic class of insects, belonging to the family Blattodea. Of the more than 4,600 species in the cockroach family, only 30 species are associated with human habitats. These insects are widely known as pests. The cockroach’s biology is fascinating, and it’s worth understanding how they live and reproduce.
Cockroaches are highly adaptable and can survive in almost any type of environment. They breathe through tiny pores on their body segments, called spiracles. This enables them to survive without a head, though they can’t drink or eat. They will eventually die because of dehydration.
Cockroaches feed on a variety of foods. A major part of their digestion of proteins takes place on the surface of the midgut cells. They also have a high concentration of aminopeptidase, which is primarily found in the microvillar membranes of the posterior midgut. However, less than five percent of their midgut contents are excreted during midgut emptying. In addition, an excess of dietary starch increases the excretion of amylase.
Cockroaches have a long life cycle. Their lifespan can extend to 600 days. They can survive on anything they can find. If you find a cockroach in your home, you should do what you can to rid it. It will be easier to eliminate the infestation if you keep your home clean and free of clutter.
