2种墨天牛摩擦发音器超微结构的比较研究

目的]探讨沟胫天牛亚科天牛摩擦发音器的发音板上是否有侧纵纹。方法]利用扫描电镜观察和比较云杉大黑天牛和云杉小黑天牛摩擦发音器的超微结构。结果]2种天牛的发音板上都有侧纵纹存在，2种天牛的发音板在形态、大小和音齿密度等方面存在较大差异，具有种的特异性。结论]结合以前发现的其他沟胫天牛种类侧纵纹的存在情况，推测这种侧纵纹在沟胫天牛亚科内具有普遍性。

Comparative Study on the Uistra-structure of Stridulation Apparatus in Two Species of Monochamus

Objective ] The research aimed to discuss whether there was lateral sulcus on stridulation apparatus of longicorn beetles of Lamiinae. Method ] The ultrastructure of stridulation apparatus of Monochamus ahernatus Hope and Monochamus sutor L. were observed and compared by using SEM. Result] There are lateral sulcus on the strldulation plate in two species of Monochamus. There were obvious differences of stridulation plate in two species of Monochamus from the shape, size, the density of sound teeth and so on, having species specificity. Conclusion] It was deduced that it was of universality for the existence of lateral sulcus in Lamiinae based on the existence of lateral sulcus in other species of Lamiinae in the former studies.
