Abstract
Induced sterility of adult males of Glossina tachiniodes irradiated with gamma doses of 130, 150 and 160 Gy, respectively, in air was investigated. The flies were irradiated at horizontal distances of 50 cm and 70 cm, respectively from the Gamma Facility. The mean percentage insemination of spermathecae ranged between 82.83 " 2.8% and 74.63 " 2.8%. All females mated and inseminated with irradiated males produced large numbers of aborted eggs and very few viable pupae. At optimum dose range between 150 Gy and 160 Gy at 50 cm horizontally from the gamma source, irradiated G. tachinoides males could achieve fertility of less than 5% (i.e., 3.7% and 0.7% fertility, respectively).
