Abstract
More than 100 countries suffer from mosquito-borne diseases which are prevalent across the world. They are the known vectors for transmission of dengue, malaria, yellow fever, filariasis, Japanese encephalitis, schistosomiasis etc. Many of the insecticides that are currently used in mosquito control have harmful effects on human health and other non-target populations, they are non-biodegradable in nature, and also have a higher rate of biomagnification in our ecosystem. The spike in insecticide resistance on a global scale is raising serious concerns. Therefore, search for natural, eco-friendly alternatives such as bio-insecticides is imperative. In this study, Larvicidal activity of the essential oil obtained from the leaves of Callistemon citrinus was tested on the Dengue vector mosquito Aedes aegypti and Chikungunya vector mosquito Culex sp. Also, the chemical composition of the essential oil was studied using GC-MS analysis. Callistemon citrinus can now be considered one of such bio-insecticides which is easily available throughout India, with many therapeutic active constituents in its essential oil and 80-100% larvicidal activity..
