Question

Male genitalia are present on

A.

7th abdominal segment

B.

8th abdominal segment

C.

9th abdominal segment

D.

11th abdominal segment

Correct option is C

The correct answer is: (C) 9th abdominal segment
Explanation:
In most insects, the male genitalia are located on the 9th abdominal segment.
This segment bears the structures responsible for copulation, including claspers and aedeagus. These structures are essential for the transfer of sperm during mating.
Important Points:
  • They include claspers for holding the female and aedeagus for sperm transfer.

  • These structures are typically present on the 9th abdominal segment across most insect species.

  • The arrangement helps in successful mating and species-specific reproduction.

Knowledge Booster:
  • 8th abdominal segment: In female insects, the 8th segment may be involved in genital openings.

  • 11th abdominal segment: The 11th segment (if present) is often reduced or vestigial in many insects.
