Abstract

To investigate the effect of Gamma radiation on the reproductive systems of emerged female and male of Ephestia cautella (Walker) moths, mature pupae of both sexes were irradiated with doses of 50, 100 and 150 Gy. Histological study of the treated individuals showed in females that the ovaries appear sever damage in the follicular epithelium at all doses, which become thinness and separated from developing oocytes, moreover, some of the nurse cells were rupture. In males which treated with 150 Gy, it was noticed retardation in the stages of spermatogenesis and few numbers of sperm bundles and their dispersion in the testicular follicles' adults, on the other hand, the doses of 50 and 100 Gy showed little or moderate effects on the structure of the testis contents.

摘要

为了研究γ辐射对黄粉虫（Ephestia cautella（Walker））雌雄成虫生殖系统的影响，用 50、100 和 150Gy 的剂量辐照成熟的雌雄蛹。对处理个体的组织学研究表明，在所有剂量下，雌性的卵巢在滤泡上皮中出现严重损伤，变得稀薄并与正在发育的卵母细胞分离，此外，一些滋养细胞破裂。在雄性中，用 150Gy 处理时，注意到精子发生阶段延迟，精子束数量减少，并且在睾丸滤泡中的成年期分散，另一方面，50 和 100Gy 的剂量对睾丸内容物的结构几乎没有或只有适度的影响。
