我们已经在虎甲虫Cicindela marutha中发现了一条携带听觉传入的神经，并描述了它们的生理反应。1.鼓膜位于第一腹背的侧缘。2.男性和女性听觉传入反应均能在30 kHz处被敏锐地调谐，灵敏度为50-55 dB SPL。3.听觉传入反应几乎没有适应性，能准确地编码刺激的时间特性，分辨率极限为6- 10 dB SPL。4.对侧和同侧传入神经对侧刺激的阈值差异在30 kHz时最大，至少为10- 10 ms。15 dB。5.消融研究表明，鼓膜前外侧角的软膜是传导的关键，而鼓膜内侧部分的传导较少。虎甲虫和蝗（蝗虫和蚱蜢）的耳朵是从同源的外围结构独立进化而来的。两种动物的鼓室器官的神经前体可能是第一腹节的胸膜弦音器官。
We have identified a nerve carrying auditory afferents and characterized their physiological responses in the tiger beetle, Cicindela marutha.1.The tympana are located at the lateral margins of the first abdominal tergum. The nerve carrying the tympanal afferents is a branch of the dorsal root from the first abdominal ganglion.2.Both male and female auditory afferent responses are sharply tuned to 30 kHz with sensitivities of 50–55 dB SPL.3.The auditory afferents show little adaptation and accurately code the temporal characteristics of the stimulus with the limit of a resolution of 6–10 ms.4.The difference in threshold between contralateral and ipsilateral afferents for lateral stimuli is greatest at 30 kHz and is at least 10–15 dB.5.Ablation studies indicate that the floppy membrane in the anterolateral corner of the tympanum is crucial for transduction while the medial portion of the tympanum is less important.6.The tiger beetle and acridid (locust and grasshopper) ears have evolved independently from homologous peripheral structures. The neural precursor of the tympanal organs in both animals is likely the pleural chordotonal organ of the first abdominal segment.
