Abstract
Males of Ceratitis capitata Wied. previously reared on three different larval media (molasses, sugar and glucose) were irradiated as old pupae with 7, 9 and 11 krad of gamma radiation. Results indicated that egg hatchability and male survival did not differ significantly in the three media at the three applied doses. Mating competitiveness of 9 krad-irradiated males at the ratio 3:1:1 (irradiated males : normal males : normal females) did not differ when using the different larval diets. When pupae were irradiated with the three doses, each given at three different dose rates, i.e. 7, 30 and 97 rad/s, a gradual decrease in egg hatchability was observed as the dose rate was increased. Adult survival was not affected by differences in either dose rate or in the radiation dose. Mating competitiveness of 9 krad-irradiated males was not affected by changes in dose rate. Old pupae were irradiated with 9 krad in three fractions at one-day interval between each treatment. Egg hatchability, male survival and male competitiveness did not differ significantly from those obtained when the dose was given in one treatment. Pupal incubation at different temperatures for two hours or two days did not affect egg hatchability in the non-irradiated
