Abstract

 

Plodia interpunctella (Hubn) male and female full grown pupae were exposed to 50, 150, 250 and 350 Gy. The ovaries and testes were investigated following the emergence of the moth. Irradiation of female pupae reduced the number of developing oocytes and fewer eggs were laid. This effect was referred to the reduction in the length of ovariole. Irradiation further induced oocyte reabsorption as compared to its occurrence in untreated insects. These effects were directly proportional to the dose applied. Exposure of male pupae to gamma rays led adversely to a decrease in the overall size of the testes in some of the emerged moths.

 

Key words: Plodia interpunctella, gamma rays, ovaries, testes.
