摘　　要：为了解内蒙古地区紫花苜蓿上半翅目昆虫的发生种类、分布范围与为害程度,作者于2013年5月-9月对内蒙古自治区5市8个乡镇紫花苜蓿上发生的半翅目昆虫进行了系统调查。共采集到共6科、19种、3 771头,经鉴定盲蝽科害虫的发生占绝对优势,主要包括:牧草盲蝽(Apolygus pratenis)Linnaeus、中黑盲蝽(Adelphocoris suturalis)(Jakovlev)、绿盲蝽(Apolygus lucorum Meyer-dür)、苜蓿盲蝽(Adelphocoris lineolatus Goeze)、三点苜蓿盲蝽(Adelphocoris fasciaticollis Reuter)、赤斑盲蝽(Polymerus cognatus Fieber)、赤须盲蝽(Trigonotylus tenuis Reuter)和短角异盲蝽(Polymerus breicornis Reuter)。通过对群落特征进行分析,结果表明除赤峰巴林右旗、巴彦淖尔市乌拉特后旗紫花苜蓿上半翅目昆虫个数、群落多样性指数、物种丰富度相对较高外,其他6个地区差异不大。最后分析了内蒙古中、东、西部区紫花苜蓿半翅目昆虫的发生与危害特点,并提出了降低盲蝽危害的栽培管理及防治建议。In order to make clear the kinds,damages and distribution of Hemiptera insects on alfalfa,Hemiptera insects on alfalfa cultivation regions of eight villages of five cities were systematically investigated from May to September in 2013. Nineteen species of six Miridae families were identified from collected specimens,all of which belonged to Heteroptera of Hemiptera. In eight investigation regions,Miridae insects were absolutely predominant species,including Apolygus pratenis Linnaeus,Adelphocoris suturalis Jakovlev,Apolygus lucorum Meyer- dür,Adelphocoris lineolatus Goeze,Adelphocoris fasciaticollis Reuter,Polymerus cognatus Fieber,Trigonotylus tenuis Reuter and Polymerus breicornis Reuter. Based on analysis on community features,the results showed Miridae number,community richness and species diversity index were relatively high; the difference of other six investigation districts was not obvious. Based on the systematic investigation,we analyzed occurrence and damage characteristics of Miridae pests on alfalfa in Inner Mongolia,and put forward cultivation management and control measures to decrease the damages of Miridae pests.
