| Abstract | ||||
| The pink bollworm, Pecbnophora gossypie/b (Saund.) was treated as newly hatched larvae by LC5,3 of the biocide compound, Dipel-2x. Also, It combined with gamma irradiation doses of 5, 10, 20, 40 & 80 Gy. On the other hand, the pink bollworm treated by LCsos of Dipel-2x exposed to gamma doses of 5, 10, 20, 40 & 80 Gy and studied the different effects of on the adults of male testis and female ovaries. The results could be summarized as follows: 1- Dipel-2x had destructive acts in disintegration of testicular epithelial septa, degeneration the germ cells, the sperm bundles and the peritoneal membrane leaving vacuolated areas and shrinking of the testis content In the male testis. Also, it reduced the size of ovaries, absence the nurse cells, dissolved the most follicular epithelial cells, vacuolated and shrinking of the oocyte or ovaries as compared with the control 2- Gamma irradiation doses of 5, 10 & 20 Gy had nearly the same effects caused by Dipel-2x. While, in case of irradiation by 40 & 80 Gy gamma doses the effects were drastically obvious. 3- Dipel-2x combined with gamma irradiation caused the highly destruction In the male testis and female ovaries which lead to reduction in the number of spermatophores or the number of deposited eggs. | ||||
