We, herein, report evidence that wing fanning by the aphid parasitoid Aphidius ervi Haliday (Hymenoptera: Braconidae) constitutes a courtship song. Complete removal of the forewings or only the distal half of them reduced male copulation success in comparison to intact males. Males that achieved copulation within the observation period produced wing fanning at a higher rate than males that did not copulate. Playback of wing fanning sound altered the behaviour of virgin females, increasing the time they devoted to grooming, as compared with subjects that were exposed to silence or white noise. Our findings contribute to the understanding of the acoustic dimension of the sensory modalities employed by this aphid parasitoid in sexual signalling.
在此，我们报告证据表明，蚜虫寄生蜂燕麦蚜茧蜂（Aphidius ervi Haliday，膜翅目：茧蜂科）的扇翅行为构成求偶之歌。与完整的雄蜂相比，完全去除前翅或仅去除前翅远端一半会降低雄蜂的交配成功率。在观察期内成功交配的雄蜂扇翅频率高于未交配的雄蜂。播放扇翅声音改变了未交配雌蜂的行为，与暴露于安静环境或白噪声的雌蜂相比，增加了它们用于梳理的时间。我们的研究结果有助于理解这种蚜虫寄生蜂在性信号传递中所采用的感官模式的声学维度。
