Songs of three Ephippigerine species (Ephippiger ephippiger, E. discoidalis and E.perforatus) have been recorded and analysed. Manipulation experiments have been carried out by removing single teeth from the pars stridens. The songs of manipulated animals show characteristic gaps within the impulse structure of the opening and closing syllables. Morphological measurements were carried out by means of SEM-photographs of the pars stridens. Combining both the bioacoustic and morphological results reveals that only the lateral part of the pars stridens is used during stridulation. Furthermore it could be shown that the individual impulse interval pattern within one syllable is also highly constant between syllables. The impulse interval pattern correlates with the pattern of tooth spacing on the pars stridens.
已对三种盔螽属物种（盔螽、盘状盔螽和穿孔盔螽）的鸣声进行了录制和分析。通过从发声区移除单颗牙齿进行了操纵实验。经操纵的动物发出的鸣声在开闭音节的脉冲结构内显示出特征性间隙。借助发声区的扫描电子显微镜照片进行了形态测量。将生物声学和形态学结果相结合表明，发声时仅使用了发声区的外侧部分。此外还发现，一个音节内的单个脉冲间隔模式在不同音节之间也高度恒定。脉冲间隔模式与发声区牙齿间距模式相关。
