Question

A male silkworm recognises female silkworm using its ______.

• A. body heat
• B. sense of sight
• C. electric signals
• D. sense of smell

Answer 1

The correct option is D sense of smell

Insects interact with each other by releasing odour/ scents. Silkworms also interact in the same way.
The female silkworm releases a unique odour which can be detected only by the male silkworm. The male silkworm then uses its strong sense of smell in order to find the female silkworm.
The sense of smell is also well developed in other animals like dogs, mosquitoes, tigers etc.
