Description/Abstract A series of experiments was performed to determine if x irradiation affected the molting of insects. The dose used was 4,700 r, half the montal dosage for adults. The insects were irradiated at a predetermined age, counted from the beginning of the third molting. Half the insects received whole-body irradiation, and in the other half the head and prothorax were protected by a lead screen. The study showed that a dose acceptable to the adult killed tbe larva of Locusta migratoria. If the irradiation was done before a centain critical time, it prevented the next molting although the insect lived beyond tbe molting date of the controls. After the critical period, the radiation is without any effect on the next molting which is produced after a perfectly normal time peniod, but the radiation prevents the following moltings. (J.S.R.)
