Question

what is the difference between male and female cockroach on the basis of anal cerci

Answer 1

• Anal cerci are a pair of appendages at the end of the abdomen, arising from near the 10^th segment of the body of cockroach. These are present in both males and females. Anal cerci are important sense organs of the organism as they are wind sensitive and detect vibrations.

• Abdomen is broader in female than in male. In male in addition to cerci, the 9^th sternum bears a short unjointed anal stylus, which are absent in females.
