Abstract

Pupae of the onion maggot, Hylemya antiqua (Meigen), did not complete their development when irradiated with 3.0 kiloroentgens within five days of pupal formation. Older pupae were not adversely affected. Females from treated pupae were sterile and laid no eggs when caged with normal males. The males from treated pupae were sterilized to a high degree, yet normal females mated with them and laid normal complements of eggs. Less than 0.2% of 10,616 eggs laid by normal females caged with sterile males hatched. A 6:1 ratio of sterile to normal flies reduced egg hatch to 1.7%.
