配偶选择对于确保物种的生存至关重要。在果蝇中，遗传学和解剖学研究几十年来一直集中在配偶识别和求偶开始上。这个模型系统已被证明是非常适合的神经系统控制决策过程的研究。然而，少得多的是知道如何求爱的质量是在一个时间动态的方式在男性和女性如何评估男性的表现，因为她使她的决定是否接受交配。在这里，我们报告说，求偶男性动态调整的相对比例的歌曲组件，脉冲歌曲或正弦歌曲，通过评估女性运动。雄蝇嗅觉缺陷未能执行运动依赖的歌曲调制，表明嗅觉线索提供了重要的信息，接近目标女性。嗅觉突变的男性也表现出较低的交配成功率与野生型女性配对时，这表明男性的能力，暂时控制歌曲显着影响女性交配的接受性。这些结果描述了连续的性间行为决策，其中雄性闻到靠近雌性的气味作为她增加的接受性的指示，并相应地协调他的歌曲选择，从而提高他成功交配的概率。
Mate selection is critical to ensuring the survival of a species. In the fruit fly, Drosophila melanogaster, genetic and anatomical studies have focused on mate recognition and courtship initiation for decades. This model system has proven to be highly amenable for the study of neural systems controlling the decision making process. However, much less is known about how courtship quality is regulated in a temporally dynamic manner in males and how a female assesses male performance as she makes her decision of whether to accept copulation. Here, we report that the courting male dynamically adjusts the relative proportions of the song components, pulse song or sine song, by assessing female locomotion. Male flies deficient for olfaction failed to perform the locomotion-dependent song modulation, indicating that olfactory cues provide essential information regarding proximity to the target female. Olfactory mutant males also showed lower copulation success when paired with wild-type females, suggesting that the male’s ability to temporally control song significantly affects female mating receptivity. These results depict the consecutive inter-sex behavioral decisions, in which a male smells the close proximity of a female as an indication of her increased receptivity and accordingly coordinates his song choice, which then enhances the probability of his successful copulation.
