Abstract: Mosquito-borne diseases have affected human and animal health in all tropical nations and subtropics of the world. New eco-friendly and sustainable vector control strategies are required to manage vector population. Silver nano particles (AgNPs) are sustainable, eco friendly an economical alternative for mosquito vector control. In present study, silver nanoparticles (AgNPs) have been synthesized using Parthenium hysterophorus leaves extract. The AgNPs synthesized were characterized using, techniques of UV visible, transmission electron microscopy (TEM) and Scanning electron microscopy (SEM) and FTIR. AgNPs synthesized were found to be spherical with size in range of 27- 40 nm. Botanically synthesized AgNPs were evaluated for their larvicidal activity against Aedes aegypti. Biosynthesized AgNPs executed higher toxicity as compared with the aqueous leaves extract with LC50 value of 1.591 μg/mL. Further AgNPs were found to be safer towards non-target organism’s P. reticulata at concentrations (LC50 and LC90) that were lethal against mosquitoes. Antimicrobial activity of Parthenium hysterophorus fabricated AgNPs was significantly higher, their average diameters of inhibition zones were higher (ranging from 3.2 mm to 23.8 mm) than those of leaves extract (ranging from 0.6 mm to 8.5 mm). Parthenium hysterophorus fabricated AgNPs are promising eco-friendly tool against mosquito vectors of medical importance.
