Objective: To evaluate to efficacy of silver and gold generated larvicide with the help of\udentomopathogenic fungus Chrysosporium tropicum against the Culex quinquefasciatus and\udAnopheles stephensi larvae. Methods: The silver and gold nanoparticles were quantified and\udobserved by the Micro-scan reader and X-ray diffraction technique. The micrographs of silver\udand gold nanoparticles were obtained by the Transmission electron microscope and Scanning\udelectron microscope. The larvicidal efficacy was then performed at six different log concentrations\udby the probit analysis. Results: The characterization study confirmed the spherical shaped\udand sized (20-50 and 2-15 nm) of silver and gold nanoparticles. The all larval stages of Cx.\udquinquefasciatus were found more susceptible to the synthesized silver nanoparticles. Whereas,\udthe larvae of An. stephensi were found more susceptible to larvicide synthesized with gold\udnanoparticles. Conclusions: The results suggested that the silver and gold nanoparticles\udgenerated by the entomopathogenic fungus C. tropicum is an environmentally safer and greener\udapproach for mosquito control and new possibility in vector control strategy
