Aedes aegypti is the primary vector for Dengue transmission in Tropical and sub-tropical countries. As per WHO in 2012, dengue ranks as the most important mosquito borne viral disease in the world. The aim of the study is to explore the efficiency of the repellent from Chloroxylon swietenia DC plant in Mosquito Control. Chloroxylon swietenia DC, are found in India and Sri Lanka and it has medicinal properties. The experiment is conducted to identify the active repellent compound using gas-chromatography coupled with electroantennogram recording (GC-EAD) analysis. GC-EAD active compounds include Dictamnine, Anthracene, Naphthalene, Nitroimidazole, Methyl-2-nitroimidazole. The identified compounds reduce the landing of female Aedes aegypti on humans. Based on this study it may be concluded that Plant extracts are effective and safe for human beings as a personal protection against mosquitoes.
