果蝇的求偶歌是由雄性果蝇的翅膀振动产生的，由间隔约为34毫秒的音调脉冲组成。melanogaster和D. simulans。这些脉冲之间的间隔不是恒定的，而是有节奏地波动，在D中周期约为1分钟。melanogaster和D. simulans。In D.在黑腹果蝇中，已经分离出3个等位基因突变，其影响影响羽化和运动活动的昼夜节律振荡器的周期性[Konopka和Benzer，1971]。每一个等位基因（pers，缩短昼夜节律周期; perI，延长昼夜节律周期;佩罗，消除昼夜节律周期）都以平行的方式显著影响60年代的歌曲节奏。昼夜节律和一个非常短的，非昼夜振荡似乎是由同一个基因的影响。
Courtship song in Drosophila is produced by the male''s wing vibration and consists of pulses of tone produced at intervals of approximately 34 ms in D. melanogaster and 48 ms in D. simulans. The intervals between these pulses are not constant but fluctuate rhythmically with periods of approximately 1 min in D. melanogaster and 0.5 min in D. simulans. In D. melanogaster, 3 allelic per mutations have been isolated which affect the periodicity of the circadian oscillators affecting both eclosion and locomotor activity [Konopka and Benzer, 1971]. Each of the per alleles (pers, which shortens the circadian period; perI, which lengthens it; and pero, which abolishes it) strikingly affects the 60-s song rhythm in a parallel fashion. Circadian rhythms and a very short, noncircadian oscillation appear to be influenced by the same gene.
