Species found in this Area


  1. Anopheles:

There are approximately 460 recognized species: while over 100 can transmit human malaria, only 30–40 commonly transmit parasites of the genus Plasmodium, which cause malaria in humans in endemic areas. Anopheles gambiae is one of the best known, because of its predominant role in the transmission of the most dangerous malaria parasite species (to humans) – Plasmodium falciparum.

The name comes from the Greek αν, an, meaning not, and όφελος, óphelos, meaning profit, and translates to useless.[1]

Some species of Anopheles also can serve as the vectors for canine heartworm Dirofilaria immitis, the filariasis-causing species Wuchereria bancrofti and Brugia malayi, and viruses such as one that causes O'nyong'nyong fever. There is an association of brain tumor incidence and malaria, suggesting that the Anopheles might transmit a virus or other agent that could cause a brain tumor.[2]

Mosquitoes in other genera (Aedes, Culex) can also serve as vectors of disease agents, but not malaria.

General Features

  • Very dark spots (patches) on wings but not on wing margins

    • Dark spots are actually veins that darken the area

  • White banding on palps






  1. Culex:


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 millimetres (0.16–0.39 in), and morphologically has the three body parts common to insects: head, thorax, and abdomen. As a fly, it has one pair of wings.



Scientists at the University of California, Davis and the Swedish University of Agricultural Sciences (SLU), have identified nonanal as a compound that attracts Culex mosquitoes.[1][2][3] Nonanal acts synergistically with carbon dioxide.[4]

  1. Culiseta:

Culiseta is a genus of mosquitoes. Most Culiseta are cold-adapted species which only occur in warmer climates during the colder parts of the year or at higher elevations where temperatures are low. The larvae of most species are found in ground waters such as bogs, marshes, ponds, streams, ditches, and rock-pools, but an African species occurs in tree-holes (phytotelma), a common eastern Palaearctic species occurs in water wells and rock-pools, and several Australian species occur underground. Little is known about the blood-feeding habits of females. Most species feed on birds and mammals, but a few feed on reptiles. Several species attack domestic animals and occasionally humans.[2]

Culiseta is found in throughout the world, except in South America.[2]
