Nowadays, the sterile insect technique is broadly used as a pest control measure. Therefore, the present study was conducted to investigate the alteration occurred in testes and DNA pattern as an effect of inherited sterility. Full grown pupae of the wax moth, Galleria mellonella were irradiated with 80 and 160 Gy of γ irradiation. The size of the testes was decreased by increasing of γ irradiation dose. Also, the size of the testes was decreased in F 1 males comparing with the size of the testes of both the parents and the untreated control. The effects of γ rays on the DNA patterns of adult male parents and F 1 males showed alterations among the controls, the treated parents and F 1 individuals. Exposure to radiation caused very frequently the appearance of some extra bands and the deficiency of others in the arbitrary random amplified polymorphic DNA-polymerase chain reaction amplification patterns of the irradiated insects.
如今,昆虫不育技术被广泛用作一种害虫防治措施。因此,本研究旨在调查遗传性不育对睾丸和DNA模式产生的变化。用80和160戈瑞的γ射线辐照完全成熟的大蜡螟蛹。随着γ射线辐照剂量的增加,睾丸大小减小。此外,与亲本和未处理对照的睾丸大小相比,F1代雄性的睾丸大小也减小。γ射线对成年雄性亲本和F1代雄性DNA模式的影响在对照、处理过的亲本和F1代个体之间表现出差异。辐射暴露在受辐照昆虫的任意随机扩增多态性DNA-聚合酶链反应扩增模式中经常导致出现一些额外条带和其他条带的缺失。
