Question

In insects, pheromone is secreted by

• A. Corpus callosum
• B. Corpus luteum
• C. Corpus albicans
• D. Corpus allata

Answer 1

The correct option is D Corpus allata

A) Corpus callosum is a band of nerve fibres that divides the cerebral cortex lobes into left and right hemispheres and provides a connection between the two.

B) Corpus luteum is a progesterone secreting structure that develops from an ovum after it has been released after ovulation in the ovary of higher animals like man and other primates.

C) Corpus albicans is the degenerated corpus luteum which no longer secretes progesterone. It is a white body.

D) Corpus allata secretes the juvenile hormone responsible for metamorphosis.

So, the correct answer is 'Corpus allata'.
