为了验证感觉反馈在鸣叫产生中的作用，我们分析了表达听觉突变的雄性果蝇的求偶鸣声。我们比较了无调式的求偶歌曲。贝多芬（btv）和触摸不敏感的幼虫b （tilB）对野生类型的歌曲。这些突变有一个共同的事实，即弦状器官被破坏。由于声带器官同时服务于听觉（在天线中）和本体感觉（来自翅膀），这两个潜在的感觉反馈途径在突变果蝇中是有缺陷的。我们测量了六个歌曲特征：脉冲序列内的脉冲数、脉冲间隔、脉冲持续时间、正弦脉冲爆发持续时间、正弦歌曲的载波频率和正弦歌曲的相对幅度。采用多变量分析。我们发现变异歌曲和正常歌曲之间存在显著差异。此外，许多突变的苍蝇在唱歌时表现出不寻常的翅膀位置。结果表明，感觉反馈在果蝇求偶鸣声的形成中起着重要作用。
To test the role of sensory feedback in song production, we analyzed the courtship songs of Drosophila males expressing auditory mutations. We compared the courtship songs of atonal (ato). beethoven (btv) and touch-insensitive-larva-B (tilB) to wild-type songs. These mutations have in common the fact that the chordotonal organs are disrupted. Since chordotonal organs subserve both hearing (in the antenna) and proprioception (from the wing), these two potential routes for sensory feedback are defective in the mutant flies. We measured six song characters: pulse number within a train, inter-pulse interval, pulse duration, sine burst duration, the carrier frequency of the sine song and the relative amplitude of the sine song. Using multivariate analysis. we found significant differences between mutant and normal songs. In addition many mutant flies exhibit an unusual wing position during singing. The results indicate that sensory feedback plays an important role in shaping the courtship song of Drosophila.
