MOSQUITOES
2500 different species of mosquitoes throughout the world
All mosquitoes must have water in which to complete their life cycle.
Each species has unique environmental requirements for the maintenance of its life cycle.

The type of water in which the larvae is found can be an aid to the identification of mosquito’s species
show a very distinct preference for the types of sources in which to lay their eggs, such as tree holes, rain water ponds, polluted water

Life Cycle :
Time needed ( egg- pupae) : 5–7 days, but many species require about 7–14 days.

Feeding habits of mosquitoes
The male mosquitoes feed only on plant juices
Only adult females that bite man and animals, so she can develop eggs.
Some female mosquitoes prefer to feed on only one type of animal or they can feed on a variety of animals.

The length of life
The length of life of the adult mosquito usually depends on : temperature, humidity, sex of the mosquito
males live about a week; and females live about a month depending on the above factors.

The flight habits of mosquitoes
Depend on the genus and species Most domestic species remain fairly
close to their point of origin. Most mosquitoes stay within a mile or two of their source.
The flight range for females is usually longer than that of males.
Wind is a factor which influence in the dispersal or migration of mosquitoes.
