The Mosquitoes
Phylum : Arthropoda
Class : Insecta
Subclass : Pterygota
Division : Endopterygota
Order : Diptera
Genus : Culex or Anopheles
Mosquitoes are found in damp and marshy localities. They are abundant in tropics and subtropics.
They are nocturnal in feeding habit. Females feed on blood (sanguivorous)of man and large animals, while males suck juices of flowers and fruit.
Because of their blood sucking adaptation, females are medically important as carriers of viral, bacterial and protozoan infection. Anopheles carries malaria, Culex carries dengue and elephantiasis and Aedes carries yellow fever.
Adult mosquitoes fly well and can cover great distance. They are able to fly without rest for 2 or 3 hours and easily cover 20 to 30 kilometers in a night.
Females become aggressive after copulation. They lay eggs in water where development of larvae and pupae takes place.
Two common mosquito genera, (Anopheles and Culex) can be easily identified by their sitting postures. When sitting, the abdomen of Anopheles is always held at an angle to the surface while that of Culex is held parallel to the surface.
