Effects of Different Doses of Gamma Rays on The Dispersal and Flight Ability Index of Mediterranean Fruit Fly Ceratitis Capitata (Wiedmann) (Diptera: Tephritidae)

Abstract

This investigation concentrated on studying the effect of gamma rays on the flight ability index and on the dispersal of irradiated males because these two parameters were very important for applying the sterile male release technique. The results of this study showed that the flight ability index of irradiated males as pupae of 3, 4 and 5 days with doses ranged from 60 to 120 Gy were highly significant p<0.05 compared with control treatment during an experiment carried out under field conditions. The results showed that there were a reverse relationship between flight ability index and gamma rays doses. Furthermore, the results of this investigation also showed that there were a reverse relationship between the mean average of males captured by the pheromone traps and gamma rays doses after 1,2,3, and 4 days from the release.
