复杂的线索集在识别和应对同种交配竞争者和避免潜在的昂贵的异种竞争相互作用方面可能是重要的。在黑腹果蝇中，雄性可以检测来自同种的感觉输入，以评估竞争的水平。它们通过显著延长交配时间来应对竞争对手，并从中获得显著的健身益处。在这里，我们测试了这样一种想法，即黑腹果蝇雄性用于检测同种的多种感觉线索也可以最大限度地减少它们可能遇到的异性雄性（果蝇simulans，果蝇yakuba，果蝇pseudobscura或果蝇virilis）的“脱靶”反应。局灶性果蝇雄性暴露于D. simulans或D. pseudobscura随后增加交配持续时间，但在较小程度上比暴露于同种竞争对手。黑腹果蝇雄性表达的竞争对手反应的大小与物种之间的遗传距离不一致，并且没有任何感觉操纵导致黑腹果蝇对所有其他测试物种的雄性做出反应。然而，当我们删除或提供“假”的感觉线索，果蝇男性变得更有可能表现出增加交配持续时间的反应，异种男性。我们认为，避免不准确的评估竞争环境的好处可能会形成识别线索的演变。
Complex sets of cues can be important in recognizing and responding to conspecific mating competitors and avoiding potentially costly heterospecific competitive interactions. Within Drosophila melanogaster, males can detect sensory inputs from conspecifics to assess the level of competition. They respond to rivals by significantly extending mating duration and gain significant fitness benefits from doing so. Here, we tested the idea that the multiple sensory cues used by D. melanogaster males to detect conspecifics also function to minimize “off‐target” responses to heterospecific males that they might encounter (Drosophila simulans, Drosophila yakuba, Drosophila pseudoobscura, or Drosophila virilis). Focal D. melanogaster males exposed to D. simulans or D. pseudoobscura subsequently increased mating duration, but to a lesser extent than following exposure to conspecific rivals. The magnitude of rivals’ responses expressed by D. melanogaster males did not align with genetic distance between species, and none of the sensory manipulations caused D. melanogaster to respond to males of all other species tested. However, when we removed or provided “false” sensory cues, D. melanogaster males became more likely to show increased mating duration responses to heterospecific males. We suggest that benefits of avoiding inaccurate assessment of the competitive environment may shape the evolution of recognition cues.
