This study demonstrates that invertebrate acoustic signals can provide information about male phenotypic attributes, and that females can use this acoustic information in mate choice to select a phenotypically superior mate. I investigated the relationships between a male acoustic sexual signal, the phenotype of the signaller, and the female response to signal variation. I recorded and analysed the calling songs of male house crickets, Acheta domesticus. The analyses showed that chirps convey information about male size. With the exception of amplitude, the mean number of pulses per chirp was the best predictor of male size. I performed a laboratory tape-playback experiment to determine female preference during phonotaxis. Females preferred tapes playing the chirps of large males, specifically chirps with a greater number of pulses per chirp. Selection on the female preference is discussed.Copyright 1997 The Association for the Study of Animal Behaviour
本研究表明，无脊椎动物的声学信号能够提供有关雄性表型特征的信息，并且雌性能够在配偶选择中利用这种声学信息来挑选表型更优的配偶。我研究了雄性声学性信号、信号发出者的表型以及雌性对信号变化的反应之间的关系。我记录并分析了雄性家蟋蟀（Acheta domesticus）的求偶鸣叫。分析表明，鸣声传达了有关雄性体型的信息。除了振幅外，每个鸣声的平均脉冲数是雄性体型的最佳预测指标。我进行了一项实验室磁带回放实验，以确定雌性在趋声行为中的偏好。雌性更喜欢播放大型雄性蟋蟀鸣声的磁带，特别是每个鸣声中脉冲数更多的鸣声。文中还讨论了对雌性偏好的选择。版权所有1997年动物行为研究协会
