Resumo: The sterile insect technique (SIT) is widely utilized in the biological control of fruit flies of the family Tephritidae, particularly against theMediterranean fruit fly.This study investigated the interaction between mating success and morphometric variation in the wings and the production of acoustic signals among three male groups of Ceratitis capitata (Wiedemann): (1) wild males, (2) irradiated with Co-60 (steriles), and (3) irradiated (steriles) and treated with ginger oil.Thecanonical variate analysis discriminated two groups (males irradiated andmales wild), based on themorphological shape of the wings. Amongmales that emit buzz signals, wild males obtained copulation more frequently than males in Groups 2 and 3.The individuals of Group 3 achieved more matings than those inGroup 2.Wild males displayed lower pulse duration, higher intervals between pulses, and higher dominant frequency. Regarding the reproductive success, the morphological differences in the wings? shape between accepted and nonaccepted males are higher in wildmales than in the irradiated ones. The present results can be useful in programs using the sterile insect technique for biological control of C. capitata.
