Abstract: The goal of the current study is to synthesise silver nanoparticles (SNPs) using Coccinia grandis leaf extract in aqueous form and assess their effectiveness against mosquito larvicidal properties. Through the use of FTIR analysis, scanning electron microscopy, and UV visible absorption, the synthesised silver nanoparticles (SNP) were identified and verified. Aedes aegypti and Culex quinquefasciatus I^st to IV^th in star larvae were assayed for 24 and 48 hours at different concentrations (50-250 ppm). Aqueous extracts from Coccinia grandis leaves exhibited noteworthy activity, while silver nanoparticles (SNP) demonstrated a notably greater mortality activity in Culex quinquefasciatus than Aedes aegypti larvae in the current investigation. The potential larvicidal activity of our study's Coccinia grandis leaf extract and synthesised SNPs suggests that this could be an excellent environmentally friendly method of control and protection. This is only an initial investigation into its larvicidal activity more research is required for deep insights of this formulation.
