摘要本文对双斑蟋蟀听觉发育的各个方面与直翅目其它动物和螳螂科动物进行了比较。末龄蟋蟀的听觉感受器细胞分支模式和一级听觉中间神经元在形态上与成体细胞非常相似;末龄蟋蟀的听觉阈值比成体高30-45 dB;大多数末龄蟋蟀的耳朵缺乏方向性;末龄蟋蟀的鼓膜与周围的角质层没有明确的分离，仍然很厚，由厚的上皮层支撑，并且缺乏微毛。 因此，听觉系统从末龄到成虫的发育显示出G.而对直翅目和螳螂科的其他种类不具有明显的遗传差异。这支持了蟋蟀听觉系统胚后发育模式与其他直翅目和Mantodea显著不同的假设。
Abstract Aspects of the auditory development of Gryllus bimaculatus are compared with those of other Orthopterans and Mantodea. Auditory receptor cell branching patterns and first‐order auditory interneurones of last‐instar crickets are morphologically very similar to adult cells; auditory thresholds are 30–45 dB higher in last instars than in adults; the ears of most ultimate nymphs lack directionality; and the tympana of last instars are not set apart clearly from the surrounding cuticle, are still thick, backed by a thick layer of epithelium, and lack microtrichia. Thus, the development of the auditory system from last‐instar to adult shows close similarities between G. bimaculatus and Teleogryllus commodus but not to other Orthopteran or Mantid species. This supports the hypothesis that the pattern of post‐embryonic development of the auditory system in crickets differs significantly from that in other Orthopterans and in Mantodea.
