Ootheca of cockroach is secreted by
Ootheca of cockroach is secreted by
Show Hint
Female cockroach possesses colleterial glands which produce the hard covering of the ootheca containing about 14--16 fertilized eggs.
Updated On: Jun 12, 2026
- Conglobate gland
- Mushroom shaped gland
- Colleterial glands
- Phallic gland
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
An ootheca is a protective capsule enclosing the eggs of a cockroach. It protects developing embryos from mechanical injury and environmental stress.
Step 1: Understand formation of ootheca. After fertilization, the eggs are enclosed in a hard, brown, capsule-like structure called ootheca. The covering material is secreted by specialized accessory reproductive glands.
Step 2: Identify the responsible gland. In female cockroach, the colleterial glands secrete proteins and other substances that harden to form the oothecal wall. Thus these glands directly participate in ootheca formation.
Step 3: Eliminate other options.
• Conglobate gland is associated with male reproductive system.
• Mushroom-shaped gland functions in male reproduction.
• Phallic gland is not responsible for ootheca formation.
Step 4: Final conclusion. The ootheca is secreted by: \[ \boxed{\text{Colleterial glands}} \] Hence option (C) is correct.
