Larvicidal Activity of Medicinal Plant against Aedes aegypti Mosquito Larvae to Control the Outbreak of Dengue

Dr. Arijit Chatterjee

Abstract: Phytochemical origin may have the potential to be used successfully as larvicides. The larvicidal activity of crude methanol extract of the bark of Azadirachta indica was assayed for the toxicity against the early fourth instar larvae of Aedes aegypti. Different concentrations 25, 50, 100, 200, 300 ppm was prepared from the stock solution. The larvicidal mortality was observed after every 12 hours of exposure, up to 48 hours. The extract showed larvicidal effects, and lower mortality rate was found in lower concentrations. However, the highest larval mortality was found in Azadirachta indica bark methanol extract at 200 and 300 ppm. The result of this study shows that crude methanol extract of the bark of Azadirachta indicamay be considered as a potent of mosquito larvicidal agent for Aedes aegypti, the carrier of DHV. The medicinal plant was easilybiodegradable than the synthetic insecticides, the products are less hazardous.
