Objective: To synthesize and characterize silver nanoparticles from aqueous root extract of\udParthenium hysterophorus (P. hysterophorus) and also to evaluate the potentiality of synthesized\udsilver nanoparticles as larvacidal agent against Culex quinquefasciatus (Cx. quinquefasciatus).\udMethods: The silver nano particles were generated using root extract of P. hysterophorus.\udThe characterization of synthesized nanoparticles was done by visual color change, UV-Vis\udspectrum, scanning electron micrograph, fluorescent microscope and Fourier transform infrared\udspectroscopy.\udResults: It was found that aqueous silver ions can be reduced by aqueous root extract of P.\udhysterophorus to generate extremely stable silver nanoparticles in aqueous medium. Larvae\udwere exposed to varying concentrations of plant extracts, aqueous silver nitrate solution and\udsynthesized silver nanoparticles for 0, 24 and 48 h separately. Aqueous root extract showed\udmoderate larvicidal effects; however, the maximum efficacy (60.18%) was observed with the\udsynthesized silver nanoparticles against the larvae of Cx. quinquefasciatus.\udConclusions: These results suggest that the green synthesis of silver nanoparticles have the\udpotential to be used as an ideal eco-friently approach for the control of the Cx. quinquefasciatus.\udThis is the first report on the mosquito larvicidal activity of the nano particle synthesized by P.\udhysterophorus
