Abstract

The potential of increased dose rate of irradiation in arthropods’ sterilization for compensating decreased doses was tested focusing on the fecundity, fertility, developmental time and longevity of the carob moth, diamondback moth, rust–red flour beetle, and two–spotted spider mite. Newly emergedadult females were irradiated at 1, 3, and 6Gy doses of gamma irradiation with 215.18, 272.34, 355.71 mGy/min rates and then were mated with unirradiated males. Fecundity and fertility of the experimental arthropods decreased by 42.1–59.5% and 9.8–29.9%, respectively. It was shown promisingly that the sterilization of arthropods could be occurred with very low doses of gamma irradiation if the respective dose rate increases effectively.
