Considering the pollution and resistance of chemical insecticides in Anopheles gambiae S.L., alternative control approaches have led to this study. Larvicidal activities of the leaves of Lantana camara, Bougainvillea spectabilis and Tephrosia villosa against the fourth instar larvae of Anopheles gambiae S.L. were evaluated. The susceptibility level and the homogeneity of wild strains were determined according to the method of Sinègre. The highest mortality rates were obtained from 15mg/ml with Lantana camara and Bougainvillea spectabilis. The larvicidal activity of Lantana camara on the wild strains was higher than Bougainvillea spectabilis. These wild strains have the same sensitivity as well as the KISUMU strain towards Bougainvillea spectabilis and Lantana camara. However, the wild population response to aqueous extracts was homogeneous against Bougainvillea spectabilis and heterogeneous against Lantana camara. Lantana camara and Bougainvillea spectabilis leaves were the most active aqueous extract on larvae of Anopheles gambiae S.L.
