Abstract: To investigate the synthesized silver nanoparticles using aqueous Mimusops elengi (M. elengi) seeds extract against two important mosquito species, Aedes aegypti and Culex quinquefasciatus. The M. elengi-synthesized silver nanoparticles (Ag NPs) were characterized by UV–vis spectroscopy, Fourier-transform infra-red (FT-IR) and further monitored by TEM and SEM. The M. elengi-synthesized Ag NPs to be effective against A. aegypti (LC50= 16.59 µg/ml; LC90= 30.46 µg/ml) and C. quinquefasciatus (LC50= 18.75 µg/ml; LC90= 33.60 µg/ml). The control showed nil mortality in the concurrent assay. The UV-visible spectroscopy showed a maximum absorbance peak at 470 nm which corresponds to the Ag NPs. The FT-IR spectrum showed prominent peaks (3433.29, 3387.00, 2924.09, 2765.92, 2364.73, 2092.77, 1774.51, 1639.49, 1508.33, 1384.89, 825.53 and 462.92 cm-1) in the region of 4000–400 cm-1. The TEM image showed the NPs with an average size of 27.44 nm. The SEM image of M. elengi-synthesized Ag NPs revealed their shape spherical, pentagonal and triangular. To conclude M. elengi-synthesized Ag NPs have a potential to be used as a drug for the control of A. aegypti and C. quinquefasciatus through eco-friendly and cost-effective approach.
