Gamma irradiation of the carob or date moth Ectomyelois ceratoniae
: dose-response effects on egg hatch, fecundity, and survival

Corn tassels were irradiated using Co 60 gamma rays at dose levels from 250 to 20,000 r. Twenty-four and forty-eight hours after irradiation the pollen was collected from the tassels and used to fertilize ears. The quantity of good seeds per ear, the germination percentage of these good seeds, and the seedling height 7 and 14 days later of the plants from these germinated seeds were recorded. No seeds were obtained beyond 4,000 r. There was little effect from pollen used 24 hours after treatment compared ivith pollen used 48 hours after treatment for any of the characters measured. There was a general dose response for number of good seeds per ear, and also in the percentage of germination of those seeds classified as good. The higher doses reduced both numbers of good seeds and their germination. There was no evident dose response of seedling height, if the seed did germinate it grew about as well as any at the dose levels measured.

Treatment Mortality

Dipping boll weevils, Anthonomus grandis Boheman, in apholate concentrations of 0.5, 0.75, or 1.0% plus 4 krads of gamma irradiation reduced egg hatch and adult emergence by an average of 88.9% and 99.7%, respectively, Mortality of treated males averaged 18.8% but was never higher than 28.0% by 5 days after treatment. Mortality of treated females averaged 76.0% after 5 days and was never less than 60.0%. By 10 days, mortality of treated males and females was never less than 96.0%. Excessive female mortality by 5 days is desirable if the treatment does not affect males. Radiation levels less than 4 krads resulted in less sterility than may be acceptable in eradication programs; less mortality was also observed at lower radiation levels.

AbstractSterility induced by gamma irradiation of the adult male tobacco budworm, Heliothis virescens (F.), was studied in two colonies, one was reared in the laboratory for more than 60 generations (laboratory strain) and the other reared for fewer than 9 generations (wild strain). When irradiated males were crossed with untreated females, the percentage egg hatch for each dose was lower with the laboratory than with the wild strain. When laboratory and wild females were crossed reciprocally with irradiated males, the fertilities were similar to those of the laboratory and wild strains, respectively. When irradiated males were crossed with female progeny from reciprocal crosses, the percentage egg hatch was similar to that of the wild strain.Wild strain females were nearly monogamous for the first several generations, but F0 females mated nearly as frequently as females of the laboratory strain.
