Objective: To evaluate the larvicidal activity of petroleum ether and ethyl alcohol extracts of\udAcorus calamus (A. calamus).\udMethods: Petroleum ether and ethyl alcohol extracts were extracted from plant materials through\udsoxhlet extraction process and its efficacy was determined through bioassay method. Extracts\udwere evaluated further for the determination of their LC\ud50 and LC90 values. Observation of mortality\udresponse was assessed after 24 h.\udResults: Petroleum ether and ethyl alcohol extracts of A. calamus produced 99% and 96%\udmortality at 125 mg/L respectively. Petroleum ether extract exhibited LC50 at 57.32 mg/L, LC90 at\ud120.13 mg/L, while ethyl alcohol extract exhibited LC50 at 64.22 mg/L, LC90 at 130.37 mg/L.\udConclusions: Present study indicated that A. calamus carries huge potential as a mosquito\udlarvicide. This potential could be exploited for the development of safer and effective botanical\udmosquito larvicidal tool for the management of Aedes aegypti
