X-ray irradiations of adult Oulema melanopus (L.) were performed with a 250-kv constant-potential X-ray machine. Survival percentages of 20 through 80% were measured in the exposure range of 0-8000 R. Only a slight difference in radiation sensitivity between the sexes was observed, but increased survival of both control and irradiated beetles was demonstrated by laboratory-reared stock when compared with corresponding groups from field collections. Sterilization exposure of 5000 Rand 3000 R were measured for males and females, respectively.
