Aedes aegypti is one of the most important disease transmitting and nuisance causing mosquitos which transmits Dengue, Chikungunya. Development of resistance in vector mosquitoes against synthetic insecticides coupled with their persistence and toxicity to non-target organisms has been widely recognized and has promoted the search for new means of control strategies. Biologically active plant extracts have been well documented for evolving an economically sound and environmentally acceptable mosquito control programmes. In the present findings, the larvicidal activity of Aristolochia bracteata against Aedes aegypti L., hexane root, ethyl acetate seed extracts have 100% mortality at 250 ppm and 500 ppm respectively. The study reveals that the root extracts of Aristolochia bracteata at 250 ppm is better for mosquito control program. This investigation clearly observes that botanical insecticides act as good toxicants and will reduce the chemical burden on the environment
