Description
Irradiation of early 5th instar nymphs of Dysdercus koenigii F. with X-ray doses ranging from 10 to 70 Gy affected their metamorphosis in a dose dependent manner. At 70 Gy dose, metamorphosis of nymphs was completely inhibited although these nymphs survived for more than 10 days. In unirradiated 5th instar nymphs, DNA content doubled between 2nd and 3rd day and it remained at this level till these nymphs completed metamorphosis. However, DNA content of nymphs exposed to metamorphosis inhibition dose of 70 Gy X-rays showed only slight increase from 4th day and its profile remained at lower level throughout 5th instar nymphal period. Though the increase in RNA content in both the groups was found to be gradual upto 3rd day, the increase was more pronounced in case of unexposed insects. (author). 9 refs., 2 tabs
