Exotic ambrosia beetles (Curculionidae: Scolytinae) in the tribe Xyleborini include destructive pests of trees growing in horticultural cropping systems. Three species are especially problematic: Xylosandrus compactus (Eichhoff), Xylosandrus crassiusculus (Motschulsky), and Xylosandrus germanus (Blandford). Due to similarities in their host tree interactions, this mini-review focuses on these three species with the goal of describing their host-selection behaviour, characterising associated semiochemicals, and assessing how these interactions relate to their management. All three of these Xylosandrus spp. attack a broad range of trees and shrubs. Physiologically stressed trees are preferentially attacked by X. crassiusculus and X. germanus, but the influence of stress on host selection by X. compactus is less clear. Ethanol is emitted from weakened trees in response to a variety of stressors, and it represents an important attractant for all three species. Other host-derived compounds tested are inconsistent or inactive. Verbenone inhibits attraction to ethanol, but the effect is inconsistent and does not prevent attacks. Integrating repellents and attractants into a push–pull management strategy has been ineffective for reducing attacks but could be optimised further. Overall, maintaining host vigour and minimising stress-induced ethanol are keys for managing these insects, particularly X. crassiusculus and X. germanus.

Xyleborini部落中的外来的甲虫（Curculionidae：Scolytinae）包括在园艺作物系统中生长的树木的破坏性害虫。三种物种尤其成问题：致密的木糖衣木（Eichhoff），景天的木糖草（Motschulsky）和德国的木糖草（Blandford）。由于它们在寄主树相互作用中的相似性，因此本小型复习集中于这三个物种，目的是描述其寄主选择行为，表征相关的化学信息素并评估这些相互作用与它们的管理之间的关系。这些木糖藻属的所有三个。攻击各种各样的树木和灌木丛。具有生理压力的树木优先受到树木的攻击X. crassiusculus和X. germanus，但是压力对X. compactus寄主选择的影响尚不清楚。乙醇是根据各种压力源从衰弱的树木中释放出来的，它代表所有这三种物种的重要引诱剂。测试的其他源自宿主的化合物不一致或无活性。马鞭草酮抑制乙醇的吸引力，但效果不一致且不能阻止攻击。将驱虫剂和引诱剂整合到推挽式管理策略中对减少攻击没有效果，但是可以进一步优化。总体而言，保持宿主活力并最大程度地减少胁迫诱导的乙醇是处理这些昆虫（尤其是欧洲角头菜蝇和德国小球菌）的关键。
