ABSTRACT

In tropical countries, mosquitoes are the major problem for the health care of human being. Hence to control them in recent years number of plant products are being used. This is because of the pollution free nature of plant derivatives which do not produce any health hazard. Biologically active plant extracts have been well documented for evolving an ecologically sound and environmentally acceptable mosquito control programmes. In the present study, the level of larvicidal activity of methanolic leaf extract of the exotic plant species, Croton bonplandianum at different concentrations viz., 25, 50, 100, 150 and 200 ppm has been investigated and it is known that the LC50 value obtained at 124 ppm is effective against the mosquito, Aedes aegypti with respect to larvicidal activity. The study revealed that the leaf extracts of C. bonplandianum at 124 ppm is better for mosquito control.
