摘　　要：[目的]评估沙枣在混交防护林中对光肩星天牛的控制能力。[方法]在内蒙古磴口县选择了3种不同混交林分,对所有树木进行逐株调查,记录相关受害指标,比较各混交林分中不同树种遭受光肩星天牛危害的情况。[结果]1)在对照组混交林带Ⅰ中,仅有沙林杨和新疆杨两种杨树混栽,两树种受害较轻且无显著差异;在混交林带Ⅱ中,包含沙林杨、新疆杨、二白杨和沙枣4个树种,其中二白杨较其他树种受害严重;在混交林带Ⅲ中,包含沙林杨、新疆杨和沙枣3个树种,沙林杨受害较重。2)新疆杨是防护林的主栽树种,在林带Ⅱ和Ⅲ中,新疆杨受害均轻于林带Ⅰ,但在3种林带中差异不显著;在林带Ⅱ和Ⅲ中的沙林杨或二白杨均受害重于新疆杨,尤其是二白杨受害严重。[结论]沙枣树的存在对光肩星天牛在新疆杨上的发生程度没有显著影响。二白杨在受调查各树种中受害最重,应是承接了大部分的光肩星天牛危害,使其可能成为虫源木,因此不建议引入混交防护林。[Objective]To evaluate the control ability of Elaeagnus angustifolia L.to Anoplophora glabripennis(Asian Longhorned Beetle,ALB)in mixed forest stands.[Method]We investigated each tree in three different types of mixed forest,recorded relative infestation indices,and compared the ALB infestation of different tree species in various forest stands.[Result]1)In mixed forest belt I(control)where only two poplar species,P.alba var.pyramidalis and P.deltoides‘Shalinyang’,were planted,no significant differences in ALB infestation were observed between the two species.In mixed forest belt II,which included the same two poplar species along with Elaeagnus angustifolia L.and Populus×xiaohei var.gansuensis,the latter species were severely infested.In mixed forest belt III,consisting of E.angustifolia,P.alba var.pyramidalis and P.deltoides‘Shalinyang’,P.deltoides‘Shalinyang’exhibited higher infestation levels compared to the other two species.;2)P.alba var.pyramidalis is the main tree species for farmland shelterbelt construction.The ALB infestations of P.alba var.pyramidalis in mixed forest II and III were slightly lower than in the belt I,but the difference was not significant.Both P.deltoides‘Shalinyang’and P.×xiaohei var.gansuensis were more heavily infested than P.alba var.pyramidalis in mixed forest belt II,with P.×xiaohei var.gansuensis showing the most severe infestation.[Conclusion]E.angustifolia did not significantly affect ALB infestation on P.alba var.pyramidalis.Among the species studied,P.×xiaohei var.gansuensis was the most severely infested,and thus appears to be the primary host for ALB in the mixed forest.Since it was seriously infested,it could act as a source of ALB spreading.Therefore,we do not recommend planting P.×xiaohei var.gansuensis in mixed protection forests.
