Question

Male mosquito (Anopheles) does not transmit malarial parasite because

• A. It lacks blood sucking mouth parts.
• B. It catches fever.
• C. It is too small to carry parasite.
• D. The parasite is killed in its stomach.

Answer 1

The correct option is A It lacks blood sucking mouth parts.

Both male and female mosquitoes feed mainly on fruit and plant nectar, but the female also needs the protein in blood to help her eggs develop. Thus, mouthparts of the females are adapted for piercing the skin of animal hosts and sucking their blood. Therefore, only female Anopheles mosquitoes bite and serve as the transmitting agents or vectors of Plasmodium which causes malaria. Thus, the correct answer is option A.
