【 摘 要 】

The current study reported the biosynthesis of silver nanoparticles (AgNPs) from aqueous leaves extract of Hippophae rhamnoides, its characterization and mosquito larvicidal potential. The biofabricated AgNPs confirmation were characterized by UV-Visible Spectrophotometer, Fourier-transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM), Energy Dispersive X-ray (EDX), X-ray diffraction (XRD) and Thermogravimetric/Differential Thermal Analysis (TGDTA).The maximum larval mortality of AgNPs against Aedes aegypti with 600 ppm at 72 hrs incubation time was 93±0.96%. The Anopheles stephensi maximum larval mortality (%) was 95±0.56 for 72 hrs at 600 ppm. The probit analysis of biofabricated AgNPs was calculated that LC50 (24 hrs), LC90 (24 hrs), LC50 (48 hrs), LC90 (48 hrs), LC50 (72 hrs) and LC90 (72 hrs) against Aedes aegypti were 394.85, 1200.00, 312.86, 853.33, 267.50 and 605.89 ppm respectively and against Anopheles stephensi were 322.69, 988.10, 281.71, 743.15, 221.88 and 656.65 ppm respectively.
