title: Inheritance of DDT resistance in species A and B of the Anopheles gambiae complex.
abstract: It has been reported that Anopheles gambiae species A is resistant to DDT in Upper Volta and Togo, and DDT resistance has been found in a Sudan strain of species B. The species A strain from Upper Volta was more resistant to DDT than the Togo strain, while the Sudan strain of species B was the least resistant. The expression of resistance is genetically determined, and studies on the mode of inheritance have shown that resistance is inherited as a single dominant gene in the Togo strain of species A and the Sudan strain of species B, but that it is inherited as a single incompletely dominant gene in the Upper Volta strain of species A.
