Over the last decades, climate change, population growth, deforestation, habitat invasion and insecticide resistance have contributed to the emergence, reemergence and dispersion of various vector-borne diseases including malaria, filariasis, chikunguniya and dengue. The larvicidal activity of aqueous extracts of neem and green-synthesized silver nanoparticles (AgNPs) was served against third instar larvae of Anopheles stephensi. Synthesized AgNPs were characterized UV-Visible spectrum analysis and high resolution TEM. AgNPs (150µl, 200µl and 250µl) and plant extracts (600µl, 800µl and 1000µl) weretested against twenty third larval instar of A. stephensi at different concentrations. All the treated and control samples were analyzed after 24 hrs. The data were analyzed by using One-Way ANOVA test and the results were found to be significant
