摘要本文通过设计Y形迷宫实验，对螽斯属的优雅蝈螽Gampsocleis gratiosa、暗褐蝈螽Gampsocleis sedakovii obscura和鸣螽属的鼓翅鸣螽Uvarovites inflatus雌虫的性选择行为和交配行为进行了观察研究。结果表明：3种螽斯的交配行为谱一致，但交配时间上有差别；3种螽斯雌虫趋于选择体重较大的雄虫交配；体重和精包重之间呈现较复杂的相关性，但均以三次函数的拟合度(R2)最大；雄虫精包重占体重均在100%以上，分别为优雅蝈螽111%、暗褐蝈螽125%、鼓翅鸣螽149%。

英文摘要：behavior and sexual selection behavior of females of three bushcrichets, Gampsocleis gratiosa, G. sedakovii obscura and Uvarovites inflatus were studied with “Y” puzzle trials. The results showed that the mating behavioral patterns of three species were roughly same, but the temporal distribution of mating was different. Females preferred to larger males. The spermatophore weight was complicatedly correlated to male body weight, in which the cubic function was best fitted with highest value of R2. Percentages of spermatophore in body weight were all more than 10.0%, i.e. G. gratiosa 11.1%, G. sedakovii obscura 125% and U. inflatus 14.9%.
