Evaluation of phytosynthesised silver nanoparticles from leaf extracts of and and their larvicidal activity against malaria, dengue and filariasis vectors.

The present study deals with the green synthesis of silver nanoparticle from the aqueous leaf extracts of and as reducing agent and to investigate the larvicidal activity of synthesized silver nanoparticles. The synthesized silver nanoparticles were characterized by Ultraviolet and visible absorption spectroscopy (UV), Fourier transform-infrared spectroscopy (FT-IR), X-ray spectroscopy (XRD), Field emission scanning electron microscope (FESEM) and High-resonance transmission electron microscopy (HRTEM) analysis. The nanoparticles are spherical, hexagonal, triangular and polyhedral in shape and the size of the Silver nanoparticles (AgNPs) of was found to be in the range of 722 nm and AgNPs of was 5-25 nm. Larvicidal bioassay with synthesized AgNPs synthesized from and extract, showed 100% mortality at 10 mg/L against , and with LC of 4.02, 4.69, 5.06 mg/L and LC of 11.22, 12.09, 12.74 mg/L and LC of 4.63, 4.04, 3.52 mg/L and LC of 12.07, 10.99, 09.61 respectively. These results suggest that the synthesized AgNPs of and have the potential to be used as an ideal eco-friendly agent for the control of the mosquito larvae.
