摘要
为有效防治芳香木蠹蛾，采用树干注射不同浓度40％氧化乐果乳油稀释液的方法，以不同树龄的稠李为实验对象，对芳香木蠹蛾1～3龄幼虫进行防治试验。经相互比较实验结果而知，在一定范围内（以对植株不产生伤害为基准），对于近似周径的稠李而言，浓度越大，防治效果越好；而同一浓度，相同的注射量，对于不同树龄而言，则周径越小，防治效果越好。
In order to control Cossus cossus orientahs Gaede effectively, this article taked Prims padus L. of different ages as experimental objects and employed the method of injecting 40% emulsified oil of oxide rogor （which has been diluted to different densities）, did some experiments on controlling Cossus cossus orientalis Gaede. By comparison, the authors reached a conclusion as followings： in proper ranges （taking doing no harm to the plants as base level）, to similar perimeters, the bigger the density is, the better the effect is; while the density and injection dosage are both the same, to plants of different ages, the smaller the perimeter is, the better the effect is.
