Bio Efficacy of Spathodea Campanulata P.BEAUV.(BIGNONIACEAE) Hexane Leaf Extract Against Dengue and Zika Virus Vector Aedes Aegypti (Diptera:culicidae).

Abstract

hatchability of Ae. aegypti eggs was decreased when placed in media of hexane leaf extract. The reduction in percent hatch was inversely proportional to the concentration of hexane leaf extract used. As the plant of the present study is widely distributed, the commercial exploitation could provide an important step in the development of new plant based insecticide as one of the alternative to expensive and environmentally harmful chemical insecticides.
