Abstract :

The aim of this study was to investigate the larvicidal potential of aqueous leaf extracts of AnisomelesMalabarica and synthesized silver nanoparticles using aqueous leaf extract against fourth instars larvae of AedesAegypti Nanoparticles are being used in many commercial applications. Young insect were exposed to varying concentrations of plant extracts and synthesized silver nanoparticles for 24 h. All extracts showed moderate larvicidal effects, however, the maximum efficacy was observed in crude methanol, aqueous, and synthesized silver nanoparticles against the larvae of AedesAegyptirespectively. The results shows that the leaf of methanol extracts of AnisomelesMalabarica and bio synthesis of silver nanoparticles have the potential to be used as an ideal eco–friendly approach for the control of the AedesAegypti. This is the first report on the mosquito larvicidal activity of the plant extracts and synthesized nanoparticles.
