Objective: To evaluate the larvicidal activity of biogenic nanoparticles against filariasis\udcausing Culex mosquito vector. Methods: The synthesized AgNPs were characterized by UVvis. spectrum, Fourier transform infrared and X-ray diffraction. Larvae were exposed to varying\udconcentrations of aqueous extract of synthesized AgNPs for 10 min. The different concentrations\udof 5, 2.5, 1.25, 0.625 and 0.312 mg/L silver nanoparticles were tested against the Culex larvae.\udResults: The mortality rate of Agaricus bisporus biogenic nanoparticles against Culex larvae are\ud5 mg/L (100%), 2.5 mg/L (81%), 1.25 mg/L (62%), 0.625 mg/L (28%) and 0.312 mg/L (11%). Conclusions:\udThese results suggest that the synthesized biogenic AgNPs have the potential to be used as an\udideal eco-friendly approach for controlling Culex larvae
