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 understand the occurrence, distribution and damage degree of Hemiptera insects on alfalfa in Inner Mongolia, the author systematically studied the Hemiptera insects on alfalfa from 8 townships in 5 cities of Inner Mongolia in May-September 2013, survey. A total of 6 families, 19 species and 3,771 heads were collected. Obviously, the occurrence of Miridae was dominant, 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. Through the analysis of community characteristics, the results showed that except for the number of hemipteran insects, diversity index and species richness of alfalfa on the Balin right banner of Chifeng and Wulatehouer Bayannaoer in Bayannur, the other six regions Little difference. Finally, the occurrence and damage characteristics of Hemiptera insects in the middle, eastern and western regions of Inner Mongolia were analyzed, and the cultivation management and prevention and cure suggestions to reduce the damage of Lygus were proposed.
