Abstract:
Larvicidal activity of Tagetes patula essential oil was tested against the fourth instar larvae of Aedes aegypti, Anopheles stephensi, and Culex quinquefaciatus. Five different concentrations of essential oil were studied and the results were compared with that of synthetic insecticide, malathion. A. aegypti (LC(50) 13.57, LC(90) 37.91) was most susceptible followed by An. stephensi (LC(50) 12.08, LC(90) 57.62) and C. quinquefaciatus (LC(50) 22.33, LC(90) 71.89).
