研究了海滨果蝇（Drosophila littoralis）、D. montana和D.雄性求偶的声音来决定雌性在选择配偶时是使用绝对标准还是相对标准。行为的女性进行了观察，当他们追求一个单一的男性生产正常的声音，或由一个单一的翅膀操纵男性生产异常的声音;当他们追求一个或两个这些男性在选择的情况。雌性通常接受短翅（但不是无翅）雄性产生异常的声音，如果他们没有选择。然而，如果他们听到正常男性发出的声音，他们会拒绝有缺陷的男性。Drosophila littoralis和D. ezoana女性之间选择两个翅膀操纵的男性与不同的翅膀面积。我们的研究结果表明，女性选择他们的配偶的基础上的相对标准，如果求爱男性发出的信号是在可接受的线索范围内。
We examined sexual selection by Drosophila littoralis, D. montana, and D. ezoana females on male courtship sounds to determine whether the females use absolute or relative criteria when choosing their mates. Behavior of the females was observed, when they were courted by a single male producing normal sounds, or by a single wing-manipulated male producing abnormal sounds; and when they were courted by one or both of these males in a choice situation. The females usually accepted short-winged (but not wingless) males producing abnormal sounds, if they had no alternatives. However, if they heard the sound produced by a normal male, they rejected the deficient male. Drosophila littoralis and D. ezoana females selected between two wing-manipulated males with different wing areas. Our results suggest that the females choose their mates on the basis of relative criteria if the signals emitted by the courting males are within the range of acceptable cues.
