Culex quinquefasciatus, known vector of west Nile virus

Culex is a genus of mosquito, and is important in that several species serve as vectors of important diseases, such as West Nile virus, filariasis, Japanese encephalitis, St. Louis encephalitis and avian malaria.

The adult mosquito can measure from 4–10 mm (0.16–0.4 in.), and morphologically has the three body parts common to insects: head, thorax, and abdomen. As a fly, it has one pair of wings.

Etymology

Carl Linnaeus used the Latin term for midge or gnat, culex, as the name of this taxon.[1]

Life cycle

The developmental cycle takes two weeks and is by complete metamorphosis. Eggs are laid singularly or in batches, depending on the species. Eggs will only hatch in the presence of water. During the larval stage the mosquito lives in water and feeds on organic matter and plants, then develops into a pupa. The pupa is comma-shaped and also lives in water. It does not feed and becomes an adult after one or two days.

Diversity

There are a large number of Culex species. In Panama alone, 88 species were described by 1955.
