[Evaluation of the sensitivity of Anopheles gambiae to fenitrothion, malathion and DDT in Senegal].

Routine tests of the susceptibility of the female of the A. gambiae complex have been carried out with Fenitrothione, Malathion and DDt in four senegalese regions. Discriminative doses of these insecticides were used with variable exposure times on unfed females caught in houses. A gambiae s. 1 showed normal susceptibility to Fenitrothion and Malathion. With DDT, the results were variable and resistance was observed in Dakar and Kolda.
