Question

Male copulatory organ in insects is known as

• A. Vas deferens
• B. Bursa copulatrix
• C. Aedeagus
• D. Testes

Hint:

Keep the reproductive structures clear: the male organ is the aedeagus, which inserts into the female's receiving organ, the bursa copulatrix, during mating.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The male reproductive system in insects consists of internal organs (testes, vasa deferentia, seminal vesicles, and accessory glands) and external genitalia used during mating.
Detailed Explanation:
Let us identify the function of each structure:
- Aedeagus (3): This is the external, sclerotized male copulatory organ in insects. It is used to deliver sperm or a spermatophore directly into the female's reproductive tract during copulation.
- Vas deferens (1): This is an internal sperm duct that transports mature spermatozoa from the testes to the ejaculatory duct.
- Bursa copulatrix (2): This is part of the female reproductive system. It is a pouch or chamber that receives the male's copulatory organ or spermatophore during mating.
- Testes (4): These are the primary male gonads where sperm development (spermatogenesis) occurs.

Step 2: Final Answer:
The male copulatory organ in insects is the aedeagus.
