摘要
通过标准地及样树调查，查明云斑天牛产卵刻槽在杨树树干上的垂直分布规律．其垂直分布位置随树龄增大而逐年上移．在2～5a生幼树上，主要分布在离地1m以下．树皮厚度是影响产卵刻相垂直分布变化及产生空槽的主要因子．
This paper reports the vertical distribution law of Batocera horsfildi's oviposition cut marks on the trunk of poplar. The oviposition place on the trunk rises with the tree's age year by year. For 2-5 year-old trees,the oviposition cut marks of Batocera horsft'eldi are distributed below the 1 meter line from the ground. The analysis result shows that thickness of the attacked bark is the main factor which influences the vertical distribution of oviposition cut marks and produces empty cut marks.
