为了解同心县林地甲虫物种组成、多样性及其危害发生情况,2015年5~10月,通过网捕法和陷阱法主要对王团、下马关、豫海、丁塘和韦州5个主要样地进行了较系统的甲虫情况调查,其中步甲科数量占绝对优势,属于优势类群。均匀度指数5个样地均处于较低水平,由高到低为下马关>豫海>丁塘>韦州>王团,优势度指数由高到低为豫海>丁塘>韦州>王团>下马关,5个采集地的物种丰富度王团最高,其次为丁塘,下马关最低。红缘天牛、沟眶象、六星吉丁、脐腹小蠹、榆跳象、柠条豆象和芫菁类是当地主要的林业害虫。
In order to understand the species composition, diversity and the occurrence of damage to the beetle in Tongxin County, from May to October in 2015, the main methods of net catching and trapping were five major A systematic survey of beetles was carried out on the plots, of which the number of Pedigree accounts for the absolute predominance and belongs to the dominant group. Evenness index was lower than that of Xiamanguan> Yuhai> Dingtang> Weizhou> Wangtuan, the dominance index descended from high to low in the order of Yuhai> Dingtang> Weizhou> Wang group> off the mark, the five species collected the highest degree of species richness, followed by Ding Tong, the lowest off the mark. Red edge beetles, ditch orbital, six-star Jidin, bellyphobia, Yu jump elephant, Caragana and Iris varieties are the main forestry pests.
