我们调查了身体质量的影响，女性交配偏好的选择性，在两个不同的感官通道（声和化学）使用领域的蟋蟀，蟋蟀整数。我们发现，身体质量影响女性的选择性的声音线索：较大的女性比较小的女性更有选择性的长途电话的男性。相比之下，体重并没有影响男性的化学线索，这是在近距离评估的选择性。然而，我们观察到这些线索的选择性。最后，声学线索的选择性与化学线索的选择性无关。这些结果表明，精力充沛的关注可能会影响交配的决定，在一定的距离和交配决定的身体质量的影响不一定是共享不同的感官方式。© 2011伦敦林奈学会，林奈学会生物学杂志，2012，105，160 - 168。
We investigated the effects of body mass on the selectivity of female mating preferences in two different sensory channels (acoustic and chemical) using the field cricket, Gryllus integer. We found that body mass affected female selectivity for acoustic cues: larger females were more selective than smaller females for long-distance calls of males. In contrast, body mass did not affect selectivity for chemical cues of males, which are assessed at close range. Nevertheless, we observed selectivity for these cues. Finally, selectivity for acoustic cues was not correlated with selectivity for chemical cues. These results suggest that energetic concerns may influence mating decisions made at a distance and that the effects of body mass on mating decisions are not necessarily shared across different sensory modalities. © 2011 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, 105, 160‐168.
