100–300 Gy Dose Experiment
The total percentage of females mated showed a high degree of irradiation dose-dependent effects (R2¼ 0.82; Table 2). Evidence of mating was observed for all females regardless for those crossed with the non-irradiated males or with males treated with doses of 100–150Gy (Table 2). Above 200 Gy doses treatments the percentage of mated females progressively decreased for both total matings and females that mated twice, while the occurrence of unmated females and those that mated once progressively increased.
