STUDIES ON HOUSEFLIES, STERILIZED WITH X RAYS
Experiments were conducted on radiosterilization of male houseflies (Musca domestica). The females are monogamous, so that all the females mating with sterile males lay sterile eggs. Tests with 24-kv x rays showed that the most satisfactory method of sterilizing male houseflies consists of irradiating the pupa with 3000 r 2 to 3 days before emergence. The mortality of the irradiated pupae was not appreciably increased and the flies emerging from them were normal in appearance, viability, longevity, and sexual activity. When the irradiated males were mated with normal females, sterility was 100% complete. However, there was a slight tendency for females mated with irradiated males to remate with normal males. Sterile males successfully competed with normal males in search of females, and when they were present in overwhelming numbers succeeded in mating with most of the females, leaving them sterile.
