Drosophila males sing a courtship song to achieve copulations with females. Females were recently found to sing a distinct song during copulation, which depends on male seminal fluid transfer and delays female remating. Here, it is hypothesized that female copulation song is a signal directed at the copulating male and changes ejaculate allocation. This may alter female remating and sperm usage, and thereby affect postcopulatory mate choice. Mechanisms of how female copulation song is elicited, how males respond to copulation song, and how remating is modulated, are considered. The potential adaptive value of female signaling during copulation is discussed with reference to vertebrate copulation calls and their proposed function in eliciting mate guarding. Female copulation song may be widespread within the Drosophila genus. This newly discovered behavior opens many interesting avenues for future research, including investigation of how sexually dimorphic neuronal circuits mediate communication between nervous system and reproductive organs.

果蝇的交配歌：雌性唱歌是为了改变雄性射精分配并煽动交配后择偶吗？
雄性果蝇通过唱求爱歌曲来实现与雌性的交配。最近发现雌性在交配时会唱一首独特的歌曲，这取决于雄性精液的转移并延迟雌性的再交配。在这里，假设雌性交配歌是针对交配雄性的信号，并改变射精分配。这可能会改变雌性的再交配和精子的使用，从而影响交配后的择偶选择。考虑了雌性如何引发交配鸣声、雄性如何对交配鸣声做出反应以及如何调节再交配的机制。参考脊椎动物的交配叫声及其在引发配偶保护方面提出的功能，讨论了交配过程中雌性信号传导的潜在适应性价值。雌性交配鸣声可能在果蝇属中广泛存在。这种新发现的行为为未来的研究开辟了许多有趣的途径，包括研究性二态性神经元回路如何介导神经系统和生殖器官之间的交流。
