摘要: <正>云斑天牛的发生及危害与林分类型,林中位置,虫源地距离及杨树品种等因素有关。观测了成虫在杨树林带中的自然扩散距离、方向及特点。成虫的扩散方向与林下植被丰富度,特别是利、充营养寄主的多寡有关。成虫具有较强的飞翔能力,测定了成虫一次持续飞行的时间、距离、高度、速度及方向等。

Abstract: The occurrence and injury of Batocera horsfieldi are related to the forest types,place in forest, distance to the pest base and poplar breeds. With the distance,directions and characteristic ofspread adults in the forest belt being measured and tested directions of spread adult are related to thenumber of vegetation,mainly to the number of host of supplementary nutrition. The adults havestronger flying ability.In this paper are also measured and tested the time,distance,hight.speed anddirections of the adults with a once-continuous flying.
