Biosynthesis of Silver Nanoparticles for Mosquito Control

Shailkh Sabah, Patil Rajesh


Biological synthesis of nanoparticles has received increased attention due to a growing need to develop environmentally benign technologies in material synthesis. In present work, silver
nanoparticles (AgNps) were synthesized intracellular by using Pseudomonas aeruginosa sp. The silver nanoparticles were characterized by transmission electron microscopy (TEM),
UV–Visible spectroscopy (UV). Larvicidal activities of silver nanoparticles were analyzed as per the standard procedures. The P. aeruginosa synthesized AgNPs were found effective
against the larvae and pupae of Cx. quinquefasciatus. The larvaes of Cx quinquefasciatus were found highly susceptible to the synthesized AgNPs at the same test concentrations. The
mortality could be observed after different hours of exposure. The present suggested that the bacterial mediated AgNPs can be used to kill larva, pupa of filarial vector and could be significantly reduce parasite transmission and therefore lead to reduced filarial risk.
