<P> The mosquito Anopheles gambiae is currently undergoing speciation into the M ( opti ) and S ( avanah ) molecular forms . Consequently , some pesticides that work on the M form no longer work on the S form . Over 3,500 species of the Culicidae have already been described . They are generally divided into two subfamilies which in turn comprise some 43 genera . These figures are subject to continual change , as more species are discovered , and as DNA studies compel rearrangement of the taxonomy of the family . The two main subfamilies are the Anophelinae and Culicinae , with their genera as shown in the subsection below . The distinction is of great practical importance because the two subfamilies tend to differ in their significance as vectors of different classes of diseases . Roughly speaking , arboviral diseases such as yellow fever and dengue fever tend to be transmitted by Culicine species , not necessarily in the genus Culex . Some transmit various species of avian malaria , but it is not clear that they ever transmit any form of human malaria . Some species do however transmit various forms of filariasis , much as many Simuliidae do . </P>
