Answer 2

Answer:

Some differences between male cockroach and female cocroach are as follows:

Male cockroach:

1. The abdomen is comparatively long and narrow.
2. The hindwings go beyond the tip of the abdomen.
3. The 8th abdominal tegrum is covered by the 7th tegram, so ventrally nine sterna are visible.
4. There is no blood pouch, or gynatrium, in the sternum.
5. The 9th sternum has a pair of slender unjointed anal styles.

Female cockroaches:

1. The abdomen is shorter and wider.
2. The hindwings reach up to the tip of the abdomen.
3. The 8th and 9th abdominal terga are hidden by the 7th tegram. So, ventrally only the first seven sterna are visible.
4. The 7th, 8th and 9th abdominal segments invaginate to form a brood pouch, or gynatrium, which serves as a mound for the ootheca.
5. Anal styles are absent.
