Aëdes

a genus of widely distributed mosquitoes occurring throughout the tropics and subtropics. Most species are black with distinct white or silvery-yellow markings on the legs and thorax. Aëdes species are not only important as vectors of DENGUE , YELLOW FEVER , FILARIASIS , and Group B viruses causing encephalitis but also constitute a serious biting nuisance. A. aegypti is the principal vector of dengue and yellow fever.
