摘　　要：苜蓿盲蝽属(Adelphocoris)昆虫是温带草原、草甸昆虫多样性的重要组分,也是豆科类牧草的重要害虫之一。内蒙古通辽市是我国北方农牧交错带重要生态生产区,目前该市天然草地苜蓿盲蝽属物种多样性及地理分布情况不明。于2021年7—9月采用五点取样法对分布于该市下辖8个行政区域天然草地共20块样地的苜蓿盲蝽属昆虫进行调查,利用扫网法进行标本采集。结果表明,通辽市天然草地苜蓿盲蝽属昆虫共有7种,其中,三点苜蓿盲蝽(A.fasciaticollis)和苜蓿盲蝽(A.lineolatus)为优势种;在所有调查样地中,大体上以扎鲁特旗巴雅尔吐胡硕镇样地和科尔沁左翼中旗协代苏木样地的苜蓿盲蝽属多样性较高,扎鲁特旗巴彦塔拉苏木样地多样性较低;2个优势种在通辽市各旗县天然草地均有分布,三点苜蓿盲蝽发生量呈由北向南递增、苜蓿盲蝽呈由北向南递减的规律。上述研究结果在以往研究基础上更系统地明确了苜蓿盲蝽属物种多样性及其优势种在通辽市天然草地的地理分布状况,为当地草地盲蝽类害虫管理与防治提供了参考数据。The Adelphocoris insects are an important component of insect diversity in temperate grass-lands and meadows.It is also one of the important pests in leguminous grasses.Tongliao City of Inner Mon-golia is an important ecological production area in the northern agricultural and pastoral transitional zone of China.At present,the species diversity and geographical distribution of the Adelphocoris in the natural grass-land of the city are unknown.From July to September 2021,five-point sampling method was used to investi-gate the alfalfa bug species distributed in 20 natural grassland plots in 8 administrative areas of the city,and the samples were collected by sweeping net method.The results showed that the natural grassland of Tongliao City consists of 7 species of the Adelphocoris,among which the A.fasciaticollis and the A.lineolatus were the dominant species.In all survey plots,the diversity of the Adelphocoris were generally higher in two sample plots of the Bayan Hushuo Town of Zhalute Banner and Xiedai Sumu of Horchin Left Banner,the diversity of the sample plot of Bayantala Sumu in Zhalute Banner was relatively low.Two dominant species were distributed in natural grasslands in various counties.The occurrence of the A.fasciaticollis increased from north to south,while the incidence of the A.lineolatus decreased from north to south.The above research results have provided a more systematic understanding of the species diversity of the Adelphocoris and geographical distribution of dominant species of this genus in the natural grasslands of Tongliao City,based on previous data,providing reference data for the management and control of local grassland bug pests.
