Abstract
Dose-fractionation studies were made with x-irradiated Tribolium castaneum larvae, Tribolium confusum adults, and Tenebrio molitor larvae. In experiments with T. castaneum larvae, it was found that if air were present between two exposures of 2.0 KR each, there was a rapid increase in survival as the interval between doses increased up to 6 hr, a slight increase between 6 and 8 hr, and a slower increase in survival with longer intervals. Recovery was absent if the larvae were kept under hypoxic conditions. Similar results were obtained with T. molitor larvae. The results obtained with T. castaneum larvae and T. confusum adults indicated that the inhibitory effect of hypoxia was reversible; significant recovery was obtained if the beetles were returned to air for at least 2 hr before the 2nd exposure. Larvae received a total dose of 4.0 KR and adults 7.2 KR. (UK)
