Culex

Culex defines one of mosquitos, and several species are vectors of important diseases, such as the Fièvre of the Western Nile ( Culex quinquefasciatus ), the Filariose, the Encéphalite Japanese woman, the Encéphalite of Saint Louis and the avian Paludisme ( Culex pipiens ).

The adult measures from 4 to 10 mm, and morphologiquement is morphologiquement composed of a head, a thorax, and an abdomen. He also has only one pair of wings which enables him to fly and to act like an important factor of dissemination of the disease.

Life cycle

The development cycle takes two weeks and implies a complete metamorphosis (what means that during the various developmental stages, the changes take place in the field of morphology and not only in the field of the size).

The eggs are laid individually or (" groups some; Nacelle s"), according to the species. They hatch in the presence of water to give a larva of first stage. The successive larval stages are watery and the larvae nourish organic matters and plants leading to acroissement of the size of the successive stages. The larvae of the sixth stage evolve/move in nymph, in the form of comma. The nymph ceases being nourished and gives birth to an adult after one day or two.
