摘要
应用扫描电镜观察了直翅目Orthoptera蟋蟀科Gryllidae油葫芦属Teleogryllus 5种油葫芦 ,即黄脸油葫芦T .emma ,黄褐油葫芦T .derelictus,银川油葫芦T .infernalis,黑脸油葫芦T .occipitalis,北京油葫芦T .mitratus的声锉结构。结果表明 ,声锉结构在种内差异不明显 ,而种间差异非常明显 ,在油葫芦属种类鉴定中有重要价值。
This paper studied the stridulating files of five species of the genus Teleogryllus Chopard from China:T. emma (Ohmachi et Matsumura),T. derelictus Gorochov,T. infernalis (Saussure),T. occipitalis (Serville), T. mitratus (Bunmeister) by using scanning electron microscope.Common characters on stridulating files of five species are teeth anvil-like, the angle small obtuse angle, length of files longer than 3.5 mm ,file reaching the angle ,number of teeth varing between 130～260. Different individuals of the same species have almost identical stridulating files, but different species often have dramatic differences in their files and teeth :length of files ,number of teeth ,density of teeth ,length of teeth ,interval between teeth ,length/width of tooth ,shape of teeth ,etc .The results revealed that the stridulating files of the genus Teleogryllus could be used as a criterion for the identification of the species.
