Mosquito vectors of Dengue and Dengue haemorrhagic fever (DHF) belong to the genera Aedes aegypti is the major vector in urban areas. The major obstacle in mosquito control program is the development of the resistance to conventional insecticides. The WHO expert committee [1] felt the resistance in vectors was probably the “biggest single obstacle in the struggle against vector-borne diseases” Most of the mosquito control programs target the larval stage in their breeding sites [2, 3]. Synthetic organic insecticides used to control mosquitoes have produced an ill effect on environment, non-targets organisms being affected and most mosquito species becoming physiologically resistant [4]. In recent times, the use of eco-friendly, biodegradable insecticides from plants to control insect vectors of diseases is gaining importance [5] and botanicals have been found to be effective [6].
