Abstract
Male pupae of Glossina morsitans were irradiated at the very late pupal stage at which females had already emerged. By the use of nitrogen and/or cooling stimulated emergence from the treated pupae could be postponed for several hours after irradiation, which would be advantageous in a sterile male project. The male survival and fertility after various doses given in nitrogen or warm or cold air were compared and it was found that a specified level of fertility could be achieved with better survival if nitrogen was used rather than air. The likely population-suppressing effect of releases of males after various possible treatments was computed, and it was concluded that a dose in nitrogen which gives incomplete sterility would be the most efficient.
