Mosquitoes are pestiferous insects, which are responsible for the transmission of various diseases. The problems caused because of mosquitoes are worldwide concern due to their inherent ability to act as intermediate host or vectors for several parasitic and viral diseases of human being and domesticated animals. Natural botanicals have provided numerous sources of phytochemicals utilized in the development of effective mosquito control agents. Biologically active plants show great promise for their potential efficiency as larvicides. The use of botanical derivatives in mosquito larvae, as an alternative to synthetic insecticides offers more eco-friendly method of insect control than the use of synthetic chemicals. The present study is focused on the larvicidal effect of essential oils against the third instar larvae of Aedes aegypti. Orange oil was found to be the potent larvicide against Aedes aegypti exhibitingpromising mortality at LC50 of 52.27 ppm, followed by other plant oils.
