Histological changes in the testes of gamma irradiated cotton leaf worm Spodoptera Littoralis (Boisd.). Vol. 4

Abstract

Male adults, less than 24 hours, of cotton leaf worm, S. Littoralis (Boisd.) were gamma irradiated with 100, 150 and 200 Gy and mated with normal females. The resulting males of each generation were used for mating normal females throughout three successive generations. Dissection of adult male parents immediately after irradiation showed no histological effects on testes. The volumes of testes of F{sub 1}, F{sub 2} and F{sub 3} generations of cotton leaf worm male moths were significantly affected by the radiation doses applied to parental males. The effects on internal anatomy and histology of the male reproductive system confirm that Gy had minimal effect on the volume and the structure of the testes among the three successive generations. Most of the sperm bundles appeared normal and the individual sperm was fully formed indicating normal metamorphosis. However, a dose of 150 Gy showed morphological abnormalities and retardation in sperm maturation. At 200 Gy the volume and structure of the testes were severely affected. Damage in the testes was highest among F{sub 1}, and was minimized in the other generations. 10 figs., 1 tab.
