Bioefficacy of Essential Oils of Lantana Camara Aculeata, Against Aedes Aegypti, Anopheles Stephensi And Culex Quinquefasciatus

Plant essential oils may act as alternatives to conventional pesticides for malaria, dengue and filariasis vector. The aim of this study was to evaluate the larvicidal activity of oil extract of Lantana aculeata against Aedes aegypti, Anopheles stephensi and Culex quinquefasciatus. Essential oil from L. aculeata was hydrodistillated and their bio components were determined by GC-MS analysis. L. aculeata essential oil was most effective against A. aegypti with LC50 11.01 ppm and LC 90 34.12 ppm, when compared to A. stephensi (LC50 11.18 ppm and LC 90 36.44 ppm) and C. quinquefasciatus (LC50 12.85 ppm and LC90 39.42 ppm). The results showed that the leaf essential oil and its bio constituents can be considered as a potent source for the production of natural larvicides.
