摘　　要：[目的]研究光肩星天牛对不同柳树的选择性,为杂交筛选抗虫性强的柳树品种提供参考。[方法]通过对北京市和河北省部分地区的柳树受光肩星天牛危害情况的调查及田间网室接虫试验,对光肩星天牛对不同寄主柳树品种(系)的选择危害情况进行了排序。[结果]在立地条件、树木年龄和树木生长状况比较一致的条件下,不同柳树品种(系)受光肩星天牛危害程度由高到低的顺序依次为:绦柳、旱柳、垂柳、馒头柳。网室接成虫试验结果与该树种在自然界的感虫情况相接近,树木对害虫的抗性,最终将反映在越冬幼虫存活数上,越冬后的幼虫将给树体带来最大的危害。根据越冬幼虫存活数,参考产卵刻槽数和孵化幼虫数3项指标综合分析,6个柳树品种(系)对光肩星天牛抗虫序列为:垂柳、馒头柳>金丝垂柳、南京柳>速生柳、旱柳。[结论]研究认为,光肩星天牛对旱柳、速生柳选择危害最重,而垂柳、馒头柳较轻。The selectivity of beetle（Anoplophora glabripennis ） for the different willow varieties was researched for the provision of a strong reference for the breeding and selection of willow variety with insect-resistance. [ Method ] The investigation of the willows damaged by beetles in some areas of Beijing and ttebei Province and the experinaent in insects＇ damage in field and net house for the order that the beetle damaging the different host willow. [ Results] Under the conditional condition of growth location, tree age and tree growth,the order of the different willow varieties（lines） damaged by the beetle was： Tao willow 〉 upland willow 〉 willow 〉 Mantou willow.It was indicated that the result from the insects＇ damage in net house test in its suscep- tible to beetle was met with the result from the natural condition. The damage of the beetle to willow was ultimately reflected in the number of surviving larvae overwinterlng and the greatest harm of larvae after its overwintering,whieh were analyzed according to three indicators： the number of surviving larvae overwintering, the number of egg-laying and the number of hatching larvae. The order of the resistance of six willow varieties（lines） to the insect was： willow, Mantou willow 〉 golden weeping willow, Nanjing willow 〉 fast-growing willow, upland willow. [ Conclusion] The beetle caused the heaviest damage to fast-growlng willow and lighter damage to willow and Mantou willow.
