While cockroaches do, indeed, have a much higher radiation resistance than vertebrates, with a lethal dose perhaps six to 15 times that for humans, they are not exceptionally radiation-resistant compared to other insects, such as the fruit fly. [67] The cockroach's ability to withstand radiation has been explained through the cell cycle. Cells ...
[5] [11] In addition to the unique flagellates, there is found bacteriocytes that are common in other cockroach species, making Cryptocercus the only cockroaches with double gut symbiosis. [12] The behaviour of proctodeal trophallaxis , the transfer of hind-gut fluids from the rectal pouch to the mouth of a receiver, allows for the vertical ...
Cockroaches are experts at surviving indoors, hiding in kitchen pipes or musty drawers. A new study uses genetics to chart cockroaches' spread across the globe, from humble beginnings in southeast ...
