We studied the courtship songs of males from several strains of Drosophila yakuba. There was clear evidence for two types of pulse songs, generated by the male's wing vibration, which we called 'thud' song and 'clack' song. Clack song was generated by both wings, at distances further from the female than the thud component, which was produced by one-wing displays. The carrier frequency of clack song was considerably higher than that of thud, whereas the interpulse intervals (IPI) of thud song, which usually predominated, were shorter. Furthermore, thud song revealed a cycling of IPIs with a period of about 70 s, significantly longer than that of D. melanogaster or D. simulans.

我们研究了几种雅库布果蝇品系雄性的求偶歌曲。有明确证据表明存在两种由雄性翅膀振动产生的脉冲歌曲，我们将其称为“砰砰”声歌曲和“咔咔”声歌曲。“咔咔”声歌曲由双翅产生，其发声位置比由单翅展示产生的“砰砰”声成分离雌性更远。“咔咔”声歌曲的载波频率明显高于“砰砰”声歌曲，而通常占主导的“砰砰”声歌曲的脉冲间隔（IPI）更短。此外，“砰砰”声歌曲显示出脉冲间隔以约70秒为周期循环，这明显长于黑腹果蝇或拟暗果蝇的周期。版权所有1999动物行为研究协会。
