在求偶过程中，雄性黑腹果蝇（Drosophilamelanogaster，Drosophilidae）通过朝向雌性的翅膀振动发出两种声音信号：脉冲歌和正弦歌。为了研究这两种鸣叫类型的作用，不同的实验信号被回放给一对果蝇（雄性果蝇通过切除翅膀而变得沉默）。为了保持声音发射的自然模式，所有的实验信号都是从一首代表性的完整歌曲中构建的，其中包括脉冲和正弦分量，在成功的求爱过程中记录下来。第一个实验表明，播放一首自然完整的歌曲恢复无翼男性求偶成功与正常的翅膀男性。在第二个实验中，我们区分了脉冲歌和正弦歌的影响，脉冲歌本身就足以刺激无翅雄性和处女雌性之间的交配;正弦歌的刺激作用较小。在第三个实验中，我们检查了修改任一信号的载波频率的后果。这对脉冲或正弦歌曲的反应没有特别的影响。这些结果表明，对于这两种信号，频率是不参与的交配成功的D。黑腹菌
During courtship, the male Drosophila melanogaster (Diptera, Drosophilidae) emits two kinds of acoustic signals by means of wing vibrations oriented towards the female: pulse song and sine song. To examine the roles of these two song types, different experimental signals were played back to single pairs of flies (with the males made mute by wing removal). To preserve the natural pattern of sound emission, all the experimental signals were constructed from a representative complete song that included both the pulse and the sine components, recorded during a successful courtship. The first experiment showed that playback of a natural complete song restored to wingless males courtship success comparable to that of normal winged males. In the second experiment, in which we distinguished between the effects of pulse song and sine song, pulse song alone was sufficient to stimulate matings between wingless males and virgin females; sine song had a less stimulating effect. In a third experiment we examined the consequences of modifying the carrier frequency of either signal. This had no particular effect on responses to either pulse or sine song. These results suggest that for both these signals, frequency is not involved in the mating success of D. melanogaster.
