Five essential oils from various parts of plant species were investigated for their larvicidal properties against Ae. aegypti and Cx. quinquefasciatus. Results showed that all the five essential oils produced significant larval mortality against two mosquito species. However the highest larvicidal activity was observed in O. basilicum oil against Ae. aegypti and Cx. quinquefasciatus with the LC50 values 75.35 ppm and 92.30 ppm respectively. However the LC50 values for A. calamus , M. arvensis, S. lappa and C. citrates against Ae. Aegypti were 99.41, 114.33, 128.89 and 136.28ppm respectively and against Cx. quinquefasciatus were 107.81, 112.18, 141.43 and 148.54ppm respectively. So according to the larvicidal activity, the essential oils were arranged in the following ascending order of preference i.e. O. bacilicum A. calamus M. arvensis S. lappa C. citrates.
