摘  要：
该文对不同杨树品种间的抗性、不同林分的被害情况以及青杨楔天牛Saperda populnea的防治技术进行了研究。结果表明,不同杨树品种间的被害率存在明显差异,小黑杨、银中杨和小叶杨被害率较低,在青杨楔天牛幼虫期采用40%氧化乐果乳油、36%虫杀星乳油涂干或36%虫杀星点涂虫瘿,其校正死亡率分别为77.15%,47.32%和87.53%。利用吡虫啉、乙酰甲胺磷原粉和大力士10倍液涂抹2 a生杨树主干,其幼虫死亡率分别为84.59%,78.52%和77.82%。

摘  要：
The resistance of different poplar lines to Saperda populnea and the damage of the pest on different poplar stands were investigated.And the control techniques against the larvae of S.populnea were also studied.The results showed that compared to other investigated poplar lines,Populus simonii×P.nigra,P.alba × P.berolinensis and P.simonii had lower infestation rate,indicating higher resistance.Compared to the damage on pure poplar stands,that on the mixed stand of poplar and Pinus sylvestris var.mongolica was lower.Coating stem with 40% omethoate EC,Shachongxing EC or coating gall with 36% Shachongxing against the larvae,the corrective mortality was 77.15%,47.32% and 87.53% respectively.Coat stem of 2-year old poplar with imidacloprid,acephate and Dalishi 10 times,the corrective mortality was 84.59%,78.52% and 77.82% respectively.
