Question

How would you differentiate between Culex and Anopheles mosquitoes pertaining to their: Eggs, Larvae and Adults.

Answer 1

Hint: A species of insect with a thin body, six legs and a pair of scaled wings is a mosquito. They have mouth parts that bite and a pair of wide compound eyes that meet each other. Culex and Anopheles eggs vary in shape, their larvae vary in feeding, and their adults have unique wings.

Complete Answer:
Worldwide, about 3,500 species of mosquitoes have been described, and they are divided into three genera: Culex, Anopheles, and Aedes. Each genus serves as a specific parasite's intermediate host. The three genera are, thus, vectors of diseases. During the blood feeding of mosquitoes, the propagation of the disease occurs.

	Culex	Anopheles
Eggs	i. Eggs are laid on the water's surface in clusters.ii. They lay eggs that are cigar-shaped.iii. Eggs lack floating lateral air.	i. Eggs are laid individually on the surface of the water in a horizontal pattern.ii. They lay eggs that are boat-shaped.iii. There are lateral air floats for eggs that make them float.
Larvae	i. The larva is a feeder from the bottom.ii. The larva’s head is round.	i. Here, larva is a feeder from the surface.ii. The larva’s head is broad.
Adults	Adults of Culex have transparent wings and are able to fly long distances.	Adults of Anopheles have dark spotted wings, unable to fly long distances.

Note: Culex acts as the intermediate host of the filarial nematodes and West Nile virus, while Anopheles acts as the definitive host of the Malaria parasite; this is the major distinction between Culex and Anopheles.
