Mosquito-borne diseases, such as malaria, filariasis, dengue hemor r hagic fever (DH F) and chikunguiniya are still imposing to be major public health problems in the Southeast Asian countries because of the tropical or subtropical climate. Aedes aegypti is known to transmit dengue and yellow fever; malaria is transmitted by Anopheles species; and filarial disease by Culex quinquefasciatus. Urbanization and changed lifestyles mainly contributed to the proliferation of larval habitats resulting in the disease epidemics. Botanical phytochemicals with mosquito larvicidal potential are now recognized as potent alternative insecticides to replace synthetic insecticides in mosquito control programs due to their excellent mosquitocidal properties and the chemicals derived from plants have been projected as weapons in future mosquito control program as they are shown to function as general toxicant, growth and reproductive inhibitors. The present study was an attempt to explore the larvicidal activity of aqueous, acetone and hexane crude extract of leaves of Hibiscus rosa-sinensis Bougainvillea, Delonix regia, Vachellia nilotica, Acacia arabica against Aedes aegypti.
