Abstract:
The contents of male Ephestia cautella testes either non-irradiated or gamma irradiated with 40 krad, were examined after 5 successive daily matings. It was found that the testes contained spermatids, as well as mature sperm, up to after the fourth mating, although their proportion decreased progressively. With males irradiated on the first day after emergence and subsequently mated with a fresh female daily, a significant rise in egg hatch, from 4·7 to 25·0 per cent from the first to the third mating was found. However, with males irradiated on the third day after emergence, no recovery in fertility was recorded. © 1975.
