Question

In mosquitoes, sex determination can be done on the basis of

• A. Size of wings
• B. Antennae
• C. Antennae and maxillary palps
• D. Ocelli.

Answer 1

The correct option is C Antennae and maxillary palps

1). Antennae are long, feathery in males and hairy in females.

2). The males suck plant sap while the females chiefly suck the blood of mammals and birds. So, female mosquito's mouth forms a long needle-like proboscis.

So, the correct answer is 'Antennae and maxillary palps'.
