Tsetse flies occur in much of sub-Saharan Africa where they are vectors trypanosomes that cause human and animal African trypanosomosis. The sterile insect technique (SIT) is currently used to eliminate tsetse fly populations an area-wide integrated pest management (AW-IPM) context Senegal Ethiopia. Three Glossina palpalis gambiensis strains [originating from Burkina Faso (BKF), (SEN) introgressed strain (SENbkf)] were established now available for use future AW-IPM programmes against West Africa. For each strain, knowledge the environmental survival thresholds essential determine which these best suited a particular environment or ecosystem, can therefore be effectively SIT programmes. In this paper, we investigated fecundity three G. p. maintained under various conditions: 25 °C 40, 50, 60, 75 % relative humidity (rH), 30 60 rH 35 rH. was dependent on temperature only, it unaffected by changing within tested range. BKF survived temperatures above its optimum better than SEN strain. SENbkf showed intermediate resistance high temperatures. A about 32 limit all strains. ranging 40 76 had no effect at 25–26 °C. We discuss implications results SIT-based control
