The aim of the study was to find out the phytochemical constituents and to evaluate the functional group of methanolic leaf extract of Anthocephalus cadamba and the biosynthesized gold nanoparticles of Cymbopogan citratus. The individual and combined effect of both were studied for growth and developmental activity against Culexquinquifasciatus. The adult development activity against freshly emerged 1st instar larvae of Culex quinquifasciatus was tested using WHO protocol. The secondary metaboliteswas analyzed using FTIR. Hence the present study clearly showed the adult emergence was greatly inhibited by the present active compounds in the methanolic leaf extract of Anthocephalus cadamba and the biosynthesized gold nanoparticles of Cymbopogan citratus.
