Abstract: Nanotechnology an emerging field of nanoscience received special attention due to their application in medicinal field. Mosquitoes transmit severe human disease leading to mortality. Usage of synthetic insecticides leads to physiological resistance and adverse environmental problems. An attempt has been made to evaluate the potential mosquitocidal and microbicidal activity of aqueous leaves extract synthesized AgNPs from Eclipta prostrata. Nanoparticle confirmation was done by surface plasmon band in Uv-vis, functional groups detecting the presence of capping agents in FTIR, crystallinity indicated in XRD. Broad spectrum of antimicrobial screening of synthesized Agnp was observed in 400 μl against Bacillus (21.1 mm) and E. coli (20.8 mm). Mosquitocidal assay suggest that the LD50 was found to be higher in Ist instar and pupae. These results recommend that the synthesized AgNPs can as an eco-friendly approach for the control of Aedes aegyptii vectors.
