The present paper deals with biopesticidal activity of seed oil of Jatropha curcas.L. on Lepidopteran pests, Cnaphalocrocis medinalis (Lepidoptera:Crambidae) rice leaf folder and Helicoverpa armigera (Lepidoptera:Noctuidae) attacking musk melon crop. Methanol, Ethanol, Petroleum ether, Ethyl acetate, Benzene, Hexane and Water extracts in three different concentrations subjected on selected pests. Jatropha curcas oil affected the amylase and LDH activity. The study reveals that 500ppm concentration of methanol for larval mortality was the most suitable solvent. A detailed statistical analysis was also carried out for both field and laboratory studies.
