甘肃省异翅亚目(半翅目)昆虫区系分析

Analysis on the faunal structure of Heteropter (Hemiptera) from Gansu Province

2001-2013年在甘肃省的主要生境,定期或不定期用扫网法采集昆虫标本,鉴定并统计其中的蝽类昆虫标本,补充分类学文献中记载的种类,首次系统整理出分布于甘肃省的异翅亚目昆虫共28科、182属、375种,其中蝽科种数最多,有85种(占22.67%).区系分析表明,甘肃省蝽类的属、种区系分布格局基本一致,均以东洋、古北双界分布型为主,体现了甘肃省蝽类昆虫区系处在古北界和东洋界的过渡地带,与华北区和华中区关系密切的特点.

The faunal structure of Heteropter(Hemiptera)from Gansu Province was analyzed base on specimens collected from 2001 to 2013 in typical habitats in Gansu and the records concerning species distribution from literatures.375 species,182 genera and 28 families of Heteropter were determined;and the results of analysis on the faunal structure showed that the faunal structure of the genera was consistent with the species,the dominant distribution pattern was Oriental-Palearctic followed by Palearctic and Oriental.The distribution pattern of Heteropter in Gansu was characteristic of a transition from Palearctic to Oriental,and more relative to Central China and North China.
