Chapter 4:Mosquitoes (anopheles and culex)

Life cycle

Mosquitoes undergo complete metamorphosis, which includes the egg, larva, pupa and adult.

After mating, about 200 eggs are layed on the surface of stagnant water. After 1 to 2 days, the eggs hatch into larvae.

The larva then moults about 3 to 4 times and develops into a pupa enclosed in a pupal skin. Within 1 to 2 days. the pupal skin splits and the adult mosquito crawls out

The adult then waits for the wings to dry and expand before it flies away. The adult live for about 2 to 3 weeks, mates, lays eggs and then dies
