“…(Bao and Dolder, 1991), According to Chapman (1998), the muscular layer may contribute to the displacement of the spermatid bundle in order to free spermatozoa into the testes and toward the posterior duct to lead out of the testis. This structure not only described in tephritidae, the same aspects of testicular organization were described in other species such as on Culex pipiens (Hassan et al, 2017) and on Blaps sulcata (Kheirallah et al 2017). Moreover, the present study confirmed the organizational pattern of mitochondrial derivatives with axoneme that was observed in the flagellate spermatozoa.…”

The journal of Toxicology and pest control is one of the series issued twice by the Egyptian Academic Journal of Biological Sciences, and is devoted to publication of original papers related to the interaction between insects and their environment. The goal of the journal is to advance the scientific understanding of mechanisms of toxicity. Emphasis will be placed on toxic effects observed at relevant exposures, which have direct impact on safety evaluation and risk assessment. The journal therefore welcomes papers on biology ranging from molecular and cell biology, biochemistry and physiology to ecology and environment, also systematics, microbiology, toxicology, hydrobiology, radiobiology and biotechnology. www.eajbs.eg.net

“…The testis structure of B. zonata appeared the same of those previously studied on Tephritidae species by Bairati (1967) on Drosophila melanogaster, Valdez (2001) on Anastrepha ludens, Hassan et al, (2017) on Culex pipiens. The result cleared that the testis of B. zonata contained an external wall surrounded the germ cells.…”

“…F1 sterility of irradiated Spodoptera litura was higher than P sterility and that F1 males inherited more sterility than did F1 females (Seth & Sharma, 2001). The acquired deleterious impacts of gamma radiation were seen in the F1, F2 and F3 generations of Culex pipiens (Hassan, Mounier, Kotb, Gabarty, & Tharwat, 2016).…”

“…Histopathological effects of gamma radiation on spermatogenesis in the Dipteran insect, Culex pipiens were recorded. Abnormal distributions of the developmental stages of spermatogonia and spermatocytes led to a general decrease in the rate of spermatogenesis, deformity of sperm, inhibiting the sperm movements and reduce the fertility (Hassan et al, 2016).…”

The southern cowpea weevil, Callosobruchus maculatus (F) is a severe agriculture pest worldwide. In the current work, newly emerged adult males of C. maculatus have been irradiated with a low dose of 20Gy gamma radiation. The inherited deleterious effects on the fecundity, hatchability, adult emergence, and the sterility percent were recorded for the progenies F1 and F2 of the irradiated parental males. The fecundity, hatched larvae, the number of males and females were reduced in both F1 and F2. The sterility percent was high in F1 (70.8%) and increased in the F2 (88.3%) generation. Histopathological effects were also documented in the testes of F1 and F2 progenies. The spermatids and sperms have exhibited a variety of abnormalities. In the early spermatids, the nebenkern outer cell membrane was ruptured. The spermatid nucleus loses its homogeneous texture and has multiple foci of dense chromatin, as well as, profiles range has little dense material. In some groups, the nucleus had a peculiar ring of chromatin. The sperms had shown a variety of aberrations. The sperms irregularity distributed in lysed cysts by unusual manner. Also, some sperms had remarkably enlarged axoneme and small rounded nucleus. Many of the sperm cells were observed with two axonemes, abnormal mitochondria derivatives, and more than two accessory bodies. These results indicate that the low dose of 20 Gy induces semi-sterility in C. maculatus through generations. The same technique would help to improve using of sterile insect technique for other agriculture pests.

“…It is evident that gamma radiation affects normal growth, development, and reproduction of insects (Hallman, 2003;Helinski et al, 2009;Kheirallah, 2016;Kheirallah et al, 2017) and may cause either sterility or mortality (Prabhakumary et al, 2011;Sengupta, 2013;Mohamed et al, 2014). A paucity of investigations reported the effect of gamma radiation on the histological and ultrastructure of insects (Paoli et al, 2014;Kheirallah 2016;Hassan et al, 2017;Kheirallah et al, 2017).…”

Abstract This study was conducted to examine the effect of gamma radiation on biological specimens. Thus, our concept is to clarify that exposure to accumulated dose of 0.2 Gy gamma rays (0.66 rad/Sec. dose rate) from Cs137 source induces cellular perturbations in the midgut epithelium of the F1 progeny of Blaps polycresta, therefore affecting nutrition and growth. Beetles were reared in laboratory conditions and the newly emerged adults were irradiated with the aforementioned dose. Histological and ultrastructure anomalies of midgut cells (digestive and regenerative cells) were observed by 72 h after radiation exposure to ensure that the cells will not return to control state. Retardation in the development of the F1 progeny was also noticed and beetles died through two weeks. In the light of these observations, biological tissue act as an indicator to the continuous exposure to environmental radiation.
