摘　　要：为明确呼和浩特市草原鞘翅目昆虫种类及分布,对鞘翅目昆虫多样性进行详细研究。2022年6月—9月,使用网捕法对设定的7条踏查路线进行昆虫采集。通过外观形态进行种类鉴定,并确定鞘翅目害虫种类,采用物种丰富度指数、多样性指数、优势度指数、均匀度指数与Jaccad群落相似性系数对采集的鞘翅目昆虫进行多样性分析。结果表明,此次调查共获得1 015个昆虫标本,经鉴定,属于17科49种。其中优势科为芫菁科和叶甲科,各占昆虫总种数的19.15%和23.40%,苹斑芫菁在各地区均有分布。和林格尔县是鞘翅目昆虫物种丰富度指数、多样性指数和均匀度指数最高的地区,优势度指数居中。不同地区间物种均匀度指数差异不大。以期明确并丰富该地区鞘翅目昆虫多样性,同时加强对害虫的预防管理工作,预防草原虫害的发生。In order to clarify the species and distribution of Coleoptera insects in the grasslands of Hohhot City,the detailed study was conducted on the diversity of Coleoptera insects.From June to September 2022,insect collection was carried out on 7 designated inspection routes using the net catching method.The species of Coleoptera pests were identified by their appearance,and the diversity of Coleoptera insects was analyzed using species richness index,diversity index,dominance index,evenness index and Jaccad similarity coefficient.The results showed that a total of 1015 insect specimens were obtained from this survey,which were identified as belonging to 49 species and 17 families.The dominant families were Meloidae and Chrysomelidae,accounting for 19.15%and 23.40%of the total insect species,respectively.Mylabris calida Pallas was distributed in various regions.The species richness index,the diversity index,and the evenness index of Coleoptera insects were the highest but the dominance index was moderate in Horinger County.The difference in species evenness index between different regions was relatively small.This study was to clarify and enrich the diversity of Coleoptera insects in the region,strengthen the prevention and management of pests,and prevent the occurrence of grassland pests.
