Application of plant extracts have become an available alternative in sustainable vector control strategy due to their less toxic, easily available and non persistant nature. In the present study, leaves, flowers and seeds of Moringa oleifera Lam. are evaluated for their larvicidal activities against Anopheles stephensi (L). The larval mortality was observed at 24hrs and 48 hrs of time exposure. Highest larval percent mortality was observed to be found in the seed extract of Moringa oleifera Lam. plant with 100% mortality at 100 ppm of concentration. LC50 value was calculated against different concentrations. The lowest LC50 value was observed in the M. oleifera Lam. seeds followed by flowers and leaves i.e. 15.17 ppm, 23.99 ppm and 38.99 ppm respectively after 24 hrs of exposure time and 12.62 ppm, 20.46 ppm and 25.11 ppm. respectively at 48 hrs of exposure time. The plant extracts also exhibited some developmental deformities in larvae and pupae. The obtained data indicates that phytochemical derived from M. oleifera Lam. seed extracts are effective mosquito vector control agent.

Abstract
Application of plant extracts have become an available alternative in sustainable vector control strategy due to their less toxic, easily available and non persistant nature. In the present study, leaves, flowers and seeds of Moringa oleifera Lam. are evaluated for their larvicidal activities against Anopheles stephensi (L). The larval mortality was observed at 24hrs and 48 hrs of time exposure. Highest larval percent mortality was observed to be found in the seed extract of Moringa oleifera Lam. plant with 100% mortality at 100 ppm of concentration. LC50 value was calculated against different concentrations. The lowest LC50 value was observed in the M. oleifera Lam. seeds followed by flowers and leaves i.e. 15.17 ppm, 23.99 ppm and 38.99 ppm respectively after 24 hrs of exposure time and 12.62 ppm, 20.46 ppm and 25.11 ppm. respectively at 48 hrs of exposure time. The plant extracts also exhibited some developmental deformities in larvae and pupae. The obtained data indicates that phytochemical derived from M. oleifera Lam. seed extracts are effective mosquito vector control agent.
