Abstract

The larvicidal activity of a botanical insecticide, Biostop Moustiques® (BM), was studied on field collected larvae of Anopheles gambiae s.l at the  concentrations of 1, 5, 10 and 20 mL/L of water. The samples were made based on three different localities of Togo: Lomé, Kovié and Kolokopé. BM had high mortality rates at 20 mL/L in all instars larvae. Specifically,  significant high mortality rates were recorded in L3 and L4 from field collected strain at a very low concentration (1 mL/L), compared to laboratory strain. In general, this study showed that the botanical insecticide tested has almost the same larvicidal effect no matter the strains of Anopheles gambiae used.

Keywords: Biostop Moustiques®, Larvicidal activity, Anopheles gambiae, Togo.
