Abstract: Dengue and Chikungunya transmitted by Aedes aegypti cause more human mortality. Use of plant based chemical as insecticide are safe and alternative method as compared to synthetic chemicals for controlling dengue virus transmission. Twenty three essential oils were screened against Ae. aegypti under laboratory condition using larvicidal and ovipostion deterrent bioassay methods. In the result of larvicidal experiment, Litsea showed effective result at four concentrations viz., 10 mg/l, 50 mg/l, 100 mg/l and 500 mg/l with the value of LC 50: 46.775 (95% CI= 30.868 - 67.463). In the study of oviposition deterrent activity, litsea showed effective repellency was 33.83%, 71.47% and 87.17% at 10 mg/l, 50 mg/l and 100 mg/l respectively. These results indicated that the essential oil of Litsea served as effective larvicidal and oviposition deterrent activity against Ae. aegypti.
