Question

Difference between male and female Anopheles occurs in
A. Proboscis
B. Wings
C. Antenna
D. Size

Answer 1

Hint: Anopheles is a type of mosquito. In addition to it, the difference between male and female anopheles is based on the mode of consumption of food. Male mosquitoes usually feed on the nectar of flowers whereas female mosquitoes depend on the mammal blood for its food.

Complete step by step answer: Anopheles is an insect which belongs to the genus mosquito of the kingdom animal. An elongated appendage from the head of an animal is called a proboscis. It refers to tubular mouthparts used for feeding and sucking in invertebrates whereas, in vertebrates, it forms the elongated nose or snout. Proboscis or the feeding tube in male anopheles is used to drink nectar from plants. Female anopheles feed on mammals for their blood by detecting the nearby human by its visual, chemical, and heat sensors. They feed on humans for blood because human blood contains protein which is a requirement of mosquito eggs to grow. When viewed under magnification male proboscis is wide and feathery whereas the female anopheles mosquito consists of a long and thin tube-like proboscis which is smooth as compared to the male anopheles mosquito. So, it is the proboscis of anopheles which differs in male and female anopheles.
Hence option A is the correct answer.

Note: There are about 460 species of anopheles which can transmit malaria disease in human beings. Because of its predominant role in the transmission of the most dangerous malaria parasite species Plasmodium falciparum to humans Anopheles gambiae is best known. Malaria is a type of fever that occurs in human beings by female anopheles mosquitoes.
