Larvicidal activity of essential oils of Jatropha curcas was evaluated on the larvae of Aedes aegypti. The larvicidal activity was determined in terms of LD50 value on late third or early fourth instar larvae for a period of 24 h. The hexane extract of J.curcas seed oil showed larvicidal effects after 24 h of exposure; with, the highest larval mortality was recorded against the fourth-instar larvae of values LC 50= 640 ppm (0.064%).No mortality was observed in the control. The results shows the seed oil extract of J.curcas can be effectively used as potential candidates for controlling Aedes aegypti and can be considered for eco-friendly vector control programs.
