The effects of ionizing radiation on the face fly, Musca autumnalis DeGeer, irradiated in nitrogen
Six day old face fly pupae, one day before emergence, were irradiated in a nitrogenous atmosphere using gamma radiation from a cobalt 60 source. Six levels of gamma radiation were used: 0, 500, 1000, 1500, 2000 and 2500 rads. The effects of gamma radiation on eclosion, reproduction, and male longevity and competitiveness were determined. Female mating habits under laboratory conditions were also examined. Irradiation under anoxic conditions did not adversely affect adult eclosion, female fecundity or male competitiveness. Sterility in treated males and females increased as radiation dosage increased. A dose of 2500 rads reduced fertility of males to less than 1% and produced similar results in the females. Longevity of treated males was not affected by increasing radiation dose up to 2000 rads. However, males receiving 2500 rads died sooner than unirradiated males. Studies on the mating habit of the female face fly showed that most of the females mated only once; however, a few of them mated a second time.
