    Journal: Sci Rep; 2022 Aug 02; 12(1):13265. PubMed ID: 35918368.
    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.
