地理上孤立的种群通常在繁殖中重要的性状上表现出表型差异。田蟋蟀鸣叫声的时间参数表型变异很大一部分与地理位置有关。不同人群录制的歌曲之间的相似性反映了地理上的接近性。我使用普通花园育种实验来确定地理和表型分布极端（夏威夷瓦胡岛和澳大利亚凯恩斯）的两个种群的歌曲之间的差异是否具有遗传基础。经过五代普通花园育种后，歌曲总持续时间和歌曲中长鸣元素比例的差异仍然存在，表明种群在这些性状上存在遗传差异。第三个鸣叫特征的差异，即声音脉冲和鸣叫之间的间隔，在普通花园育种后消失，这表明这些特征中种群之间的差异代表了表型可塑性，或者种群由于适应实验室环境而趋同。对群体内遗传变异模式进行了前瞻性分析。全同胞分析表明歌曲特征存在高水平的遗传变异。家庭平均协方差矩阵表明，不同人群的歌曲遗传结构有所不同。两个群体的女性都喜欢长鸣元素比例较高的歌曲，并且偏好似乎具有较高的遗传和残余变异性，尽管这些参数的采样方差很高。几乎没有证据表明女性对长鸣元素的偏好与其兄弟产生的长鸣元素的数量之间存在相关性。
Geographically isolated populations often show phenotypic divergence in traits important in reproduction. A large proportion of the phenotypic variation in temporal parameters of the calling song of the field cricket Teleogryllus oceanicus is related to geographical location. Similarity between the songs recorded in different populations reflects geographical proximity. I used a common-garden breeding experiment to determine whether differences between the songs of two populations from the extremes of the geographical and phenotypic distribution (Oahu, Hawaii and Cairns, Australia) have a genetic basis. Differences in the total song duration and the proportion of the long-chirp element in the song remained after five generations of common-garden breeding, indicating that the populations had diverged genetically for these traits. Differences in a third song trait, the intervals between sound pulses and chirps, disappeared after common-garden breeding, suggesting that either the difference between populations in these traits represents phenotypic plasticity or the populations converged as a result of adaptation to the laboratory environment. A prospective analysis of the patterns of genetic variation within populations is presented. Full-sib analyses suggested high levels of genetic variability in song traits. Family mean covariance matrices suggested that populations differ in the genetic architecture of their songs. Females from both populations preferred songs with a high proportion of the long-chirp element, and preferences appeared to have high genetic and residual variability, although the sampling variances on these parameters were high. There was little evidence of a correlation between female preference for the long-chirp element and the amount of the long-chirp element produced by their brothers.
