摘　　要：调查开封地区15块麦田田埂杂草中的节肢动物群落数量,采用典范相关分析方法研究麦田田埂杂草与昆虫群落关系.结果表明:田埂杂草中有节肢动物11目36科,优势种是灰飞虱(Laodelphgax striatellus)和异色瓢虫(Harmonia axyridis);田埂杂草益害比值为0.81;典范相关分析显示田埂上杂草的高度是影响田埂昆虫群落的一个重要因子.Quantity of arthropod community was investigated systematically in the grasses on the 15 wheat field ridges in Kaifeng.The method of canonical correlation analysis is applied to the study of the relation between the grasses on the wheat field ridges and insect community.The result shows the arthropod community includes 11 orders,36 families on grasses on the 15 wheat field ridges.Dominant species are Laodelphgax striatellus and Harmonia axyridis Pallas.The ratio between natural enemies and insect pests in the grasses on the wheat field ridges is 0.81.The results of canonical correlation analysis show the height of the grasses is identified as the important factor influencing the insect community in the grasses on the wheat field ridges.
