摘　　要：盲蝽多植食性,为草原常发昆虫类群,是生物多样性的重要组成。于2017—2018年每年6月末至9月初采用扫网法对内蒙古东部草原盲蝽多样性及分布进行调查,旨在为后续草原盲蝽进一步研究提供基础资料。共采集盲蝽1825头(34属65种),其中科尔沁草原858头(20属34种),呼伦贝尔草原967头(27属52种)。科尔沁草原以斯氏后丽盲蝽(Apolygus spinolae)、条赤须盲蝽(Trigonotylus caelestialium)和小欧盲蝽(Europiella artemisiae)为优势种;呼伦贝尔草原以苜蓿盲蝽(Adelphocoris lineolatus)、青草绿盲蝽(Lygus gemellatus)及红楔异盲蝽(Polymerus cognatus)为优势种。呼伦贝尔草原盲蝽的Margalef丰富度指数(7.42)、香农指数(3.04)和辛普森多样性指数(0.93)均较高;Pielou均匀度指数以科尔沁草原稍高(0.77)。盲蝽亚科在属、种数分布上表现为呼伦贝尔草原明显较高,但在个体数分布上两草原差异不明显。合垫盲蝽亚科在属、种和个体数分布上两草原均不具明显差异。叶盲蝽亚科则在属、种和个体数分布上均表现为科尔沁草原较高。两个草原盲蝽物种相似性系数为0.32。可见,呼伦贝尔草原盲蝽多样性高于科尔沁草原,两草原盲蝽物种中等不相似。Most mirid bugs are phytophagous.As a common insect group in grasslands,it is an important component of biodiversity.From the end of June to the beginning of September in both2017 and 2018,we investigated the diversity and distribution of mirid bugs by sweeping net method,with the aim to provide basic data for further research.A total of 1825 individuals were collected,belonging to 65 species and 34 genera.Among them,858 individuals(34 species,20 genera)were from Horqin grassland and 967 individuals(52 species,27 genera)from Hulunbuir grassland.Apolygus spinolae,Trigonotylus caelestialium,and Europiella artemisiae were dominant species in Horqin grassland,while Adelphocoris lineolatus,Lygus gemellatus and Polymerus cognatus were the dominant species in Hulunbuir grassland.The Margalef richness index(7.42),Shannon index(3.04),and Simpson diversity index(0.93)of mirid bugs were higher in Hulunbuir grassland,whereas Pielou evenness index(0.77)was higher in Horqin grassland.The genera and species richness in subfamily Mirinae was obviously higher in the Hulunbuir grassland,though the difference in abundance between the two grasslands was not significant.There was no obvious difference between the two grasslands in the abundance and number of genera and species in subfamily Orthotylinae.The subfamily Phylinae had higher number of genera and species,and abundance in Horqin grassland.The similarity coefficient of mirid bug species between the two grasslands was 0.32.It was concluded that the diversity of mirid bugs in Hulunbuir grassland was higher than that in Horqin grassland,and that species compositions were moderately dissimilar between the two grasslands.
