Mosquitoes are one of the most dangerous vectors among the group of arthropods. Infections due to mosquitoes are a major worldwide health problem, with high endemicity in developing countries. In the present study, we determined the larvicidal activity of Methanol, Acetone, Hexane, Chloroform and Aqueous extracts of a mangrove plant Excoecaria agallocha against (4th instar larvae) Aedes aegypti and Culex quinquefasciatus. Mosquito larvicidal assays were conducted and their mortality rate was identified after 24hours to evaluate the larvicidal activity of the crude extract of Excoecaria agallocha.
