Abstract

The selected plant fruits were collected, shade dried, ground and extracted with methanol and ethanol. The larvicidal activities of Rauvolfia serpentina fruits extract against 3rd instar larvae of Aedes aegypti using of WHO procedure. The mortality rate was observed at 12.5, 25, 50, 100 and 200 ppm of concentrations after 24, 48 and 72 hours. The highest larval mortality was found in ethanolic extract at the concentration of 200 ppm after 48 hours of the treatment. No mortality was found in control. The Rauvolfia serpentina fruits extract showed good larvicidal activity against A. aegypti, and thus the products can be used effectively as indigenous mosquito control agents, alternative to conventional chemical mosquito larvicides.
