大多数果蝇物种产生特定物种的雄性求爱歌曲作为其precopulatory求爱剧目的一部分。雌性通常在受到适当的歌声刺激时交配最快。不寻常的是，雄性的果蝇lini和它的兄弟物种唱正弦歌曲只有在交配。D. lini和Drosophila ogumai，而大西果蝇（Drosophila ohnishii）则较低。Drosophila ogumai和D. lini是异地分布的，D. ohnishii可能与D. ogumai或D. lini。我们对每个物种进行了播放实验，以研究正弦歌曲频率的作用。交配持续时间延长。lini或D. ogumai和雌蛾的高频（240-250 Hz）人工鸣叫。Ohnishii当用低频（170-180 Hz）人工歌曲刺激时。这表明，正弦歌曲频率延长交配持续时间在三个物种和物种的典型歌曲是更有效的。我们还研究了D。lini和D.以评估其遗传控制。对D. lini和D. ohnishii的研究表明，正弦振动频率主要是由于加性常染色体变异，尽管也发现了X染色体的超亲效应和母体或Y连锁效应。由爱思唯尔有限公司代表动物行为研究协会出版。保留所有权利。
Most Drosophila species produce species-specific male courtship song as part of their precopulatory courtship repertoire. Females usually mate most quickly when stimulated with appropriate song. Unusually, males of Drosophila lini and its sibling species sing sine song only during copulation. Sine song frequency is high in D. lini and Drosophila ogumai and lower in Drosophila ohnishii. Drosophila ogumai and D. lini are allopatric, although the range of D. ohnishii may meet or overlap with that of D. ogumai or D. lini. We conducted playback experiments with each species to examine the role of sine song frequency. Copulation duration increased for females of D. lini or D. ogumai when stimulated with high-frequency (240-250 Hz) artificial song and for females of D. ohnishii when stimulated with low-frequency (170-180 Hz) artificial song. This suggests that sine song frequency extends copulation duration in the three species and that species-typical song is more effective. We also examined song frequency in crosses between D. lini and D. ohnishii to assess its genetic control. Analysis of F1 and backcross generations between D. lini and D. ohnishii showed that sine song frequency is mainly due to additive autosomal variation, although a transgressive effect of the X chromosome and maternal or Y-linked effects were also found.
