In the present study the larvicidal and pupicidal activity of green synthesized silver nanoparticles by the aqueous leaf extract of Aristolochia bracteata against Aedes aegypti was carried out in laboratory condition. The silver nanoparticle synthesis was primarily confirmed by the of brown colour formation in the reaction mixture within 1 day incubation period. The silver nanoparticles synthesis in the reaction mixture was further confirmed by UV-Vis spectroscopy showed an absorption band at 371.50nm. SEM analysis provided the shape of sliver nanoparticle was mostly aggregated and spherical and the size of the green synthesized silver nanoparticle from Aristolochia bracteata was 18 to 352nm. FTIR analysis showed the synthesizes silver nanoparticles had many absorption bands. LC50 values were calculated. Larval mortality, pupal mortality and adult mortality of Aedes aegypti against Aristolochia bracteata were noted.
