The mating performance of G lossina palpalis gambiensis V anderplank ( D iptera: G lossinidae) mass‐reared in B urkina F aso ( BKF strain) was compared with that of target populations originating from the B amako peri‐urban area of the N iger R iver B asin, M ali ( MLI strain) and the N iayes area, S enegal ( SEN strain). The tests were carried out using a field cage either set up outdoors in B urkina F aso or inside the laboratory in Austria. The target population strains ( MLI and SEN ) were a few generations from the wild whereas the laboratory‐reared flies ( BKF ) were adapted to laboratory rearing over many generations. The laboratory‐reared BKF strain significantly out‐competed the MLI strain in the mating tests, but showed close to equal competitiveness with the SEN strain. At least one‐third of possible matings occurred during each observation period. The females from the two target populations readily mated with males from the BKF strain. The selected mating parameters and behaviour in the cage showed that there was mating compatibility between the strains and this absence of obvious mating barriers indicates the potential of using BKF strain males in programmes that have a sterile insect technique (SIT) component targeting the two G . p. gambiensis populations of M ali and S enegal.
