title: [Resistance of Anopheles gambiae s.l. to pyrethroids and DDT at Tiassalékro, an irrigated rice-growing village in the southern forest of Ivory Coast].
abstract: An assessment of the sensitivity of Anopheles gambiae s.l.to three pyrethroids (alphacypermethrin, permethrin, deltamethrin) and DDT has been carried out with a laboratory strain (Kisumu reference sensitive strain) and a wild strain (Tiassalékro strain) using larvae from an irrigated rice-growing area of Tiassalékro, located in the southern forest of Ivory Coast. The sensitivity tests were performed according to the standard WHO cylinder tests with adult female A. gambiae s.l. aged 2 to 4 days. The results showed that the strain of Tiassalékro is resistant to the three tested pyrethroids and DDT. The molecular forms M and S were identified, with a predominance of M form. The resistance mechanism involved is the Kdr mutation. In this region, control measures against malaria vectors by using bed nets impregnated with these insecticides or household sprays could be compromised.
