【摘要】 本文比较了不同种类的蝉鸣声和听觉特性。结果表明，蝉类用于飞行趋声的鸣声种特性不仅与鸣声的优势频率有关，而且与鸣声的音调和节奏的变化有关。同时，鸣声的优势频率与相应的生态环境有关，其飞行趋声范围一般不超过２００ｍ，主要范围约１００－６０左右。更多还原

【Abstract】 The song and hearing propertics in different species of cicadas are compared in this paper. The results show that the song properties serving the purpose of night phonotaxises in cicadas are not only related to dominant frequencies of songs, but also are related to tontic and rhythmic variations of songs.Moreover, the dominant frequentes of songs are related to habitat enviroments, and the flight phonotactic regions are generally below 200 m, the main region is about 60-100 m.更多还原
