Which of the Following Does Not Help in Excretion in Cockroaches?
WouterThe excretory system of a cockroach is made up of several different organs that help remove waste from the body. Its main excretory organs are the Malpighian tubules, a pair of coiled tubes that runs the length of the cockroach’s body. These tubules filter waste products from the blood and excrete them through the anus.
The cockroach’s digestive system has several bacterial species that help it excrete waste. These organisms are able to process uric acid and transport it to the gut where it is catabolized by uricolytic microorganisms. These bacteria, such as Bacteroides and Streptococcus, can degrade uric acid into ammonia in the hindgut of cockroaches.
Cockroaches produce uric acid as a waste product. This substance provides a rich reserve of nitrogen for the insects. However, the cockroach must have recycling mechanisms in place to ensure that it does not waste this valuable resource. Cockroaches excrete waste nitrogen as uric acid, which is used as a supplement to dietary nitrogen in times of low dietary nitrogen. Cockroaches also contain Blattabacterium, a vertically transmitted Gram-negative bacteria that is thought to participate in the degradation of uric acid. It is also hypothesized to be involved in nitrogen assimilation and nutrient provisioning.
Cockroaches have adapted to living in human habitats and are therefore difficult to eradicate. These insects are considered a nuisance and may cause severe health problems. They produce a noxious odor, are allergic to humans, and are a significant cause of emotional distress.
