Abstract: The ovicidal and larvicidal efficacy of essential oils extracted from the tubers of <b style=""><i style="">Cyperus</i></b><b style=""><i style=""> giganteus </i>Vahl</b><i style=""> </i>and<i style=""> <b style="">Cyperus</b><b style=""> rotundus</b></i><b style=""> Linn.</b><i style=""> </i>was studied on eggs and fourth instar larvae of <i style="">Aedes</i><i style=""><span style="color: rgb(35, 31, 32);"> albopictus </span></i><span style="color: rgb(35, 31, 32);">(Skuse). The eggs and larvae were exposed to serial concentration of the oils ranging from 5-150 ppm and kept under observation for 24 h. Both the oils showed remarkable ovicidal and larvicidal activities indicated by EC<sub>50 </sub>values of <5ppm and LC<sub>50</sub> and LC<sub>90</sub> values of <20 ppm<span style="color: rgb(35, 31, 32);">. The results obtained suggest that the essential oils of these <i style="">Cyperus</i> species can serve as a<span style="color: rgb(35, 31, 32);"> potential source of natural mosquitocidal agents.</span></span></span>
