The sterile insect technique (SIT) is widely utilized in the biological control of fruit flies of the family Tephritidae, particularly against the Mediterranean 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. The canonical variate analysis discriminated two groups (males irradiated and males wild), based on the morphological shape of the wings. Among males 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 in Group 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 wild males than in the irradiated ones. The present results can be useful in programs using the sterile insect technique for biological control of C. capitata.
不育昆虫技术（SIT）被广泛应用于实蝇科果蝇的生物防治，尤其是针对地中海实蝇。本研究调查了三种地中海实蝇（Ceratitis capitata (Wiedemann)）雄性群体在交配成功率、翅形态测量变异以及声学信号产生方面的相互作用：（1）野生雄性；（2）经钴-60辐照的（不育）雄性；（3）经辐照（不育）并经姜油处理的雄性。典型变量分析基于翅的形态形状区分出两组（辐照雄性和野生雄性）。在发出嗡嗡声信号的雄性中，野生雄性比第2组和第3组的雄性更频繁地获得交配。第3组个体比第2组个体实现了更多交配。野生雄性的脉冲持续时间较短，脉冲间隔较长，且主频较高。关于繁殖成功率，野生雄性中被接受和未被接受的雄性在翅形上的形态差异比辐照雄性中的更大。目前的结果可用于利用不育昆虫技术对地中海实蝇进行生物防治的项目。
