Abstract

The objective of the present study was to evaluate the larvicidal activity of silver nanoparticles synthesized from aqueous extracts of Hibiscus vitifolius Linn flowers against the larvae of Aedes aegypti. Stable silver nanoparticles were synthesized by biological reduction method. The parasite larvae were exposed to varying concentrations of aqueous extract of Hibiscus vitifolius flowers and synthesized silver nanoparticles for 24 h as per World Health Organization protocols. Distilled water served as control. Percentage mortality was recorded. The synthesized nanoparticles exhibited significant larvicidal activity. This method is considered as an innovative alternative approach using green nanochemistry technique to control vector parasites and is the first report on mosquito larvicidal activity of Hibiscus vitifolius Linn flowers mediated synthesized silver nanoparticles.
