摘要
通过对江西萧氏松茎象发生林区118块标准地的调查与分析,得出萧氏松茎象平均虫口密度与有虫株率之间的关系可用指数函数Y=15.6 e0.031 3x来描述。
Based on the analyses of the data from the investigation of 118 slash pine plots infested by Hylobitelus xiaoi Zhang, the relationship between the mean larval population density of H. xiaoi Zhang and the ratio of infested trees could be described as the equation: Y = 15.6e^0.0313x
