摘要：
With a goal of inimizing application of environmentally hazardous chemical insecticides, an attempt was made to formulate a biocontrol insecticide against mosquito and mosquito larvae. The larvicidal activity of Solarium xanthocarpum and Cucurbita maxima against Culex quinquefasciatus was studied with different solvent extracts. The larvicidal activity was determined against the third instar larvae of Culex quinquefasciatus at four different concentrations such as 250ppm, 500ppm, 750ppm and 1000ppm. Distilled water with desired amount solvents were used as control. Larval mortality was assessed after 24h, 48h and 72h. A very high mortality rate was found in acetone extract of Solarium xanthocarpum and in ethyl acetate extract of Cucurbita maxima when compared to other extracts. The Larval spray and Mosquito repellant agarbhathi were formulated with highly effective extracts. Activity was tested and the compounds present in these extracts were separated by column chromatography and analyzed for phytoconstituents using GC-MS analysis.
