dc.description.abstractIn this study silica (SiO2), zinc (Zn) and silica/zinc (SiO2/Zn) composite nanoparticles were synthesized using aqueous leaves extract of Azadirachta indica as a simple, cheap and ecofriendly green material as a simple, cheap and ecofriendly material. The present study is based on the investigation of SiO2, Zn and SiO2/Zn composite nanoparticles against 2nd instar Aedes aegypti larvae. The green synthesized nanoparticles were characterized with scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy analysis. Larvicidal bioassay tests were conducted at various doses of NPs for 24 hours. Mortality data was subjected to probit analysis to determine the LC50, LC90, and LC99 values. Results demonstrated high potency of ZnO NPs against 2nd instar A. aegypti larvae. ZnO NPs gave a great larvicidal effect against A. aegypti larvae. Although, larvae treated with all the nanoparticles showed probit of mortality to be linear and R2 <1. But green synthesized ZnO NPs showed more significant results as compared to silica, and silica/zinc composites nanoparticles. These findings suggest that green synthesized NPs could serve as an alternative potent technology for mosquito vector control
