Factors influencing sterility and vitality of the Mediterranean fruit fly, Ceratitis capitata Wiedemann

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  More>>

Pupal incubation at different temperatures for two hours or two days did not affect egg hatchability in the non-irradiated group. On the other hand, pupal incubation at both 5/sup 0/ or 15/sup 0/C either for two hours or two days prior to irradiation resulted generally in a significant reduction in the percentages of sterility compared with 25/sup 0/C. Practically, there was no effect on male survival of either the temperature or the incubation period to which the pupae were exposed prior to irradiation. However, the male competitiveness was better when the pupae were incubated at 5/sup 0/ or 15/sup 0/C for two days rather than for two hours.}
