The effects of gamma irradiation on the screwworm fly, Cochliomyia hominivorax , were reexamined to determine an optimum combination of dose, age, and stage for treatment that would not affect the quality of the sterile fly. Test insects from the mas

The flight mill performance of 1-, to 18-day-old laboratory-reared screwworm flies, Cochliomyia hominivorax (Coquerel), was studied as a measure of fly vigor. Variation of flight performance among individuals was great. Generally, young screwworms we
