摘要： 为摸清贵州独山黑麦草人工草地鞘翅目昆虫种类组成及发生情况，采用网捕、陷阱及目测法收集统计记录甲虫种类和数量，总结分析其发生程度。初步结果鉴定出鞘翅目昆虫10 科33 种，叶甲科古铜凹胫跳甲(Chaetocnema concinnicollis)为优势类群；发生程度较高的有害种群有：豆长刺萤叶甲(Atrachya menetriesi)、褐足角胸叶甲(Basilepta fulvipes)、细角长跗跳甲(Longitarsus succineus)、斑鞘豆肖叶甲(Pagria signata)，鞍象(Neomyllocerus hedini)、黑斑尖筒象(Nothomyllocerus illitus)、暗色槽缝叩甲(Agrypnus musculus)和筛阿鳃金龟(Apogonia cribricollis)；发生程度较高的天敌种群有：黄斑青步甲[Chlaenius (Achlaenius) micans]、逗斑青步甲[Chlaenius (Pachydinodes) virgulifer]、中华婪步甲(Harpalus sinicus)、爪哇屁步甲(Pheropsophus javanus)、星斑虎甲(Cylindera kaleea)、纵条瓢虫(Brumoides sp.)和龟纹瓢虫(Propylea japonica)；其他种群零星发生。黑麦草人工草地生态环境具有相对稳定的鞘翅目种类组成，需警惕古铜凹胫跳甲成为黑麦草人工草地的主要害虫，注意保护利用其天敌类群。

Abstract: The purpose of this paper was to test species composition and occurrence of beetles (Coleoptera) in ryegrass (Lolium perenne) artificial pasture in Dushan County of Guizhou. Sweeping method, pitfall traps along with ocular estimation were used in the field collections, and the occurrence of beetles was summarized based on the collections. 33 species of beetles which belonged to 10 families in Coleoptera were identified. Chaetocnema concinnicollis was the dominant species. The main pests were Atrachya menetriesi, Basilepta fulvipes, Longitarsus succineus, Pagria signata, Neomyllocerus hedini, Nothomyllocerus illitus, Agrypnus musculus and Apogonia cribricollis. The main natural enemy beetles were Chlaenius (Achlaenius) micans, Chlaenius (Pachydinodes) virgulifer, Harpalus sinicus, Pheropsophus javanus, Cylindera kaleea, Brumoides sp. and Propylea japonica. The quantity of other species was low. The species composition of beetles was relatively stable. Chaetocnema concinnicollis was potential beetle pest, which might possibly become one important pests of artificial pasture. The conservation and utilization of natural enemy should be considered in pest control.
