| 摘要: |
| 对蟪蛄Platypleura kaempferi(Fabr.)的自然鸣声、一般形态及发音器构造详细比较分析的结果表明：蟪蛄的鸣声与其发育器构造相统一，即：主发音器官鼓膜决定了声脉冲的特性，而辅发音器官背瓣、腹瓣、褶膜、腹室等又具有改善波形和调谐作用。蟪蛄的鸣声是由大部分高频成份和少量低频成份组成的复合声；鸣叫节律明显而有规律，变调过程在波形上可明显分为3部分，且这3部分交替进行，构成其完整的鸣叫过程。单鸣声和求偶交配声更具种的专一性，受内外界因素影响较小．可作为鸣声分类较理想的鸣叫类型。 |

| Abstract: |
| The natural song,structure of sounding organ and common morphology of kaempfer cicada(Platypleura kaempferi(Fabr.))are studied.The results showed :the sounding organs structure of kaempfer cicada is in accordance with its function,the main sounding organ(tymbal)determines the characters of sound pulse,but the auxiliary sounding organs(tymbal cover,operculum, folded membrane,abdominal cavity)can improve timbre and harmonious; The song of kaempfer cicada is the complex sound that mostly consists of high-frequency and a few low-frequency; The sound rhythm is clearand regula;its waveform is obviously classified into three parts which are alternating,thus,forming a complete song-process. The single song and courtship song show the specificity of the species less affected by the inside and outside environments. Accordingly,they can be regarded as some ideal characters of taxonomy. |
