Nanotechnology is an interdisciplinary science deals with the synthesis and application of nanoparticles. The synthesis of metal nanoparticles came in to light due to wide range of applications in different fields. Biosynthesis of silver nanoparticles by plant extracts is a cost effective, ecofriendly and less time consuming process where the seconadary metabolites present in the plant extracts acts as reducing and stabilizing agents of silver nanoparticles. In the present days people are suffering from dengue and malaria due to increased rate of mosquitoes and another side agriculture is under threat due to increased rate of pests. The green synthesized silver nanoparticles (AgNPs) are showing remarkable results in controlling the population of both vector and pests. In the present review the nature of different insect vector and pests were discussed. The article also contains the nature of different plants which were used in the synthesis of silver nanoparticles. This review mainly focussed on the insecticidal activity of plant mediated silver nanoparticles against selected insect vectors and pests.
