B. Piercing and sucking
C. Biting and sucking
D. Biting and chewing

Answer 1

Hint:-Mosquitoes are the insects which mainly depends on the liquid food for their survival
and their lifecycle, based on the lifecycle the source of food for mosquitoes are different, and male
mosquitoes feed on plant juices, while female mosquitoes feed on the blood of humans.

Complete step-by-step solution:-
1. Mouthparts of mosquitoes are called Proboscis, and they all are of 6 types which help the
mosquitoes to feed on their food.
2. The proboscis or feeding tube present in the mosquitoes helps them to take their food.
3. When coming to anopheles mosquito the female one causes malaria fever in humans, as we
know that mosquitoes act as vectors and they carry various parasites and responsible for
transmitting the disease, but male mosquitoes do not act as vectors because they feed on
flower nectar for food, rather human blood.
4. So both the male and female Anopheles mosquitoes are feeding on liquid food, and they do rely
on solid food, they have sucking type of mouthparts, and both male and female should pierce
the tissues, to suck the food, so the mouthparts of mosquitoes can be called as Piercing and
sucking type.
5. As the proboscis of male anopheles mosquito are the long and feathery type they go for plant
juices such as nectar of flowers.
So the correct answer is piercing and sucking type, and the correct option is B.

Note:- The reason for the female mosquitoes to feed on the blood rather than plant juices like male Anopheles mosquito is, they have larva stage, so they require blood to obtain some proteins which
help to feed the larva and help for their development.
