  • Abstract

    The present study was carried out to investigate antimosquito (insecticidal) activity of methanol, chloroform and petroleum ether extracts of two medicinal plants Hemidesmus indicus and Swertia chirata against second instar larvae of Aedes aegypti. The insecticidal activity of different concentrations of solvent extracts was found to be dose dependent. Among extracts, H. indicus showed more larvicidal efficacy when compared to S. chirata. Overall, it was found that the chloroform extract was more effective in killing larvae followed by ethanol and petroleum ether extracts. The larvicidal efficacy of solvent extracts may be due to the presence of phytochemicals in the extracts. Further, isolation of active constituents from solvent extracts and determination of insecticidal efficacy of isolated constituents are to be carried.
