Relation to man.
Mosquitoes rank first in importance among the insect that transmit disease to man.
This is partially because their biting habits vary among genera and species with regard to habitat, time of day, and host type and availability. The genera most frequently associated with disease transmission are Aedes Anopheles and Culex. Besides serving as disease vectors, many species of mosquitoes are serious pests of man solely because of their irritating bites. Mosquitoes oviposit on the surface of water or on surfaces subject to flooding. Larvae hatch and feed on organic matter in the water, pupate, and eventually metamorphose into adults.
