Abstract: Study on the usage of essential oil for the control of mosquitoes transmitting vector borne diseases has been receiving renewed interest for last two decades as they are target specific and environmentally safe as compared to the synthetic products. In the present investigation, an attempt was made to evaluate the efficacy of essential oil from the leaves and peel of Citrus grandis (C. grandis) against different developmental stages of dengue vector Aedes aegypti. Results showed that the essential oils from the leaves possess more ovicidal activity (LC50 value 9.56ppm) than the peel at 72 hour. As larvicidal, the essential oil from the peel of C. grandis showed more effect with LC50 value 61.71ppm than the leaves (LC50 value 126.45ppm at 72 hour) of the plant. There was not much adulticidal potential recorded in oil extracted from leaves but the oil extracted from peel showed moderate adulticidal activity with LC50 value 174.96ppm against the mosquito. Thus it can be inferred that the essential oil from C. grandis is a potential candidate for the control of different developmental stages of Aedes aegypti.
