摘　　要：对江西省萧氏松茎象发生区104块标准地调查和分析后得出被害寄主上萧氏松茎象流脂点与虫口密度之间的关系可用幂函数y=0.452 4x1.012 1来描述。Based on the analysis of the data from the investigation on 104 slash pine plantations infested by Hylobitelus xiaoi Zhang, relationship between the number of resin exits caused by H. xiaoi larvae and their mean population density could be described as the equation：y=0.4524x^1.0121.

关 键 词：萧氏松茎象 流脂点 虫口密度 数学模型
