[Sensitivity of Anopheles gambiae s.l. to insecticides in the Selingue dam area].
In the Selingue hydroelectric dam area the An. gambiae complex members are susceptible to DDT, resistant to dieldrin (the adults mainly) and also susceptible to temephos, chlorpyrifos, fenthion, fenitrothion and malathion. The LC50 of the larvae for fenthion is 0.00325 ppm. Due to the abundance of An. gambiae s.s. in this area (nearly 98%), it is probable that these data refer mainly to this species. Recent cytogenetic studies have shown that this species is composed of three chromosomal types (Bamako, Savanna and Mopti) with partially reproductive isolation. In the case of resistance of members of a species complex to an insecticide, it will be of great interest to know how this resistance is distributed within the complex. This can be particularly important for An. gambiae s.s. and An. arabiensis, and also for the chromosomal forms Bamako and Mopti of An. gambiae s.s. which are reproductively well isolated.
