摘要: 首次利用计算机技术对迷卡斗蟋Velarifictorus micado (Saussure)的鸣声特征 及其生物学意义进行了研究。结果表明:迷卡斗蟋在不同性比条件下,鸣声的声学特征不同。雄性独处时发出召唤声;2只以上的雄性在一起时会发出警戒声、挑战声或胜利声;1雄1雌在一起时会发出欢迎声、求爱声,如果雌性不理会雄性的求爱时则会发出一种催促声。利用计算机 ,除了对人们用耳辨别的3种鸣声(召唤声、求偶声和争斗声)进行客观记录外,还可以对以前所称的“求偶声”和“争斗声”进行更细致地分析和比较。根据其生物学意义,作者首次将其 鸣声分为7种,并对这7种鸣声在功率谱和时域两方面进行了比较,发现迷卡斗蟋在不同行为下 有不同的鸣声特征,传递不同的信息。

Abstract: The structure, spectra and temporal parameters of sounds of Velarifictorus micado under different conditions were studied by acoustic analysis techniques. The results show that the sounds can be classified into 7 types of songs: calling, warning, provoking, victory, welcome, courting and urging song. The experiments show that the characteristics of these 7 types of songs are distinguished in acoustic properties with specific behavior and biological information.
