内蒙古草盲蝽复合组昆虫群落结构及区系

为摸清草盲蝽复合组昆虫在内蒙古地区的群落结构组成和地理分布特点,于2006—2012年,采用网捕法对内蒙古草盲蝽复合组昆虫进行野外调查,根据已有标本并结合相关资料对内蒙古草盲蝽复合组昆虫进行了较系统的研究。结果表明,内蒙古草盲蝽复合组昆虫已定名标本5属21种,其中草盲蝽属、后丽盲蝽属为优势类群。内蒙古草盲蝽复合组昆虫在世界动物地理区划组成上以古北界分布占优势(52.38%),古北界+东洋界跨区分布的次之(28.58%)。内蒙古草盲蝽复合组昆虫在中国动物地理区划组成上以蒙新区种类为主体(23.82%),且蒙新区、华北区和东北区的草盲蝽复合组昆虫亲缘关系较为密切。在内蒙古植被带中,草盲蝽复合组分布于典型草原带的物种最多,有19种,占总种数的90.48%,其中,仅分布在草原带的物种有9种,占物种总数的42.86%,由此可看出,草盲蝽复合组昆虫是对草原生境较为适应的类群。

Community structure and fauna of Lygus complex in Inner Mongolia

According to the existing specimens and related documents, the community structure and fauna of Lygus complex of Inner Mongolia were studied systematically from 2006 to 2012 using net capture method. The results showed that 5 genus 21 species were indentified. Among of them, the Lygus and Apolygus were dominant group. In the zoogeographic regions of world, the species of Palaearctic distribution were dominant, about 52.38%; and those species spanned the Palaearctic and Oriental distribution accounting for 28.58% followed. In the zoogeographic regions of China, the species of Mongolia-Xinjiang region was predominant, for 23.82%. The genetic relationship of Lygus complex distributed in Mongolia-Xinjiang region, North China region and Northeast China region were more closely. In the vegetation zone of Inner Mongolia, species of Lygus complex distributed in the typical steppe were the most (19 species), accounting for 90.48% of the total species. There were 9 species only distributed in the steppe zone, accounting for 42.86% of the total species. Research showed that Lygus complex was a kind of group which was more adapted to grassland habitat.
