BACKGROUNDIps typographus (L.), the eight‐toothed spruce bark beetle (Coleoptera: Scolytinae), has devastated European Norway spruce (Picea abies ) forests in recent years. For the first time, I. typographus has established localized breeding populations in Britain, where Sitka spruce (P. sitchensis ) is a critical component of plantation forestry. The interactions between Norway spruce and I. typographus are well understood, but relatively little is known about the susceptibility of Sitka spruce to the beetle. This study aimed to determine whether I. typographus would select Sitka, compared to Norway spruce, as a host for breeding, and to study the chemical ecology underlying these host preferences.RESULTSHost choice assays were conducted in the laboratory using freshly cut spruce logs, and then verified in the field in an area with an endemic population of I. typographus . Overall, colonization and breeding success were found to be similar in cut Sitka and Norway spruce material. The response of I. typographus, reared on both Norway and Sitka spruce, to headspace extracts of aged and fresh Norway and Sitka spruce material was tested behaviorally using four‐arm olfactometry. Odors of aged wood from the two species were equally attractive, and fresh Sitka was more attractive than fresh Norway spruce. Antennal responses to Norway Spruce and Sitka Spruce headspace extracts were located using GC‐EAG and identified by coupled GC‐mass spectrometry and GC co‐injection with authentic standards. Norway‐ and Sitka spruce‐reared beetles did not differentiate between synthetic Norway or Sitka spruce blends and responded similarly.CONCLUSIONThese findings suggest I. typographus will select and colonize cut Sitka as readily as cut Norway spruce, with implications for its establishment risk in Sitka‐growing regions. Whilst the susceptibility of live Sitka trees remains unclear, the study advances the understanding of the role of both host‐emitted volatile organic compounds (VOCs) in primary host location and induced host preference in host selection by I. typographus. © 2025 Crown copyright and The Author(s).

调查 Ips typographus 对西加云杉的威胁:一种破坏性森林害虫对英国主要商业针叶树的歧视和定植
背景Ips typographus (L.),八齿云杉树皮甲虫(鞘翅目:Scolytinae),近年来摧毁了欧洲挪威云杉 (Picea abies) 森林。I. typographus 首次在英国建立了本地化的繁殖种群,那里的西加云杉 (P. sitchensis) 是人工林业的重要组成部分。挪威云杉和 I. typographus 之间的相互作用是众所周知的,但对锡加云杉对甲虫的易感性知之甚少。本研究旨在确定 I. typographus 是否会选择与挪威云杉相比,Sitka 作为繁殖宿主,并研究这些宿主偏好背后的化学生态学。结果在实验室使用新鲜切割的云杉原木进行选择测定,然后在 I. typographus 特有种群的地区进行田间验证。总体而言,发现切割的 Sitka 和 Norway 云杉材料的定植和繁殖成功相似。使用四臂嗅觉测量法对在挪威云杉和锡加云杉材料上饲养的 I. typographus 对陈年和新鲜挪威云杉和锡特加云杉材料的顶空提取物的反应进行了行为测试。这两个树种的老木气味同样吸引人,新鲜的 Sitka 比新鲜的挪威云杉更有吸引力。使用 GC-EAG 定位触角对挪威云杉和西加云杉顶空提取物的反应,并通过 GC-质谱联用和 GC 与真实标准品共进样进行鉴定。挪威云杉和锡加云杉饲养的甲虫不区分合成挪威云杉或锡加云杉混合物,反应相似。结论这些结果表明 I. typographus 将像切割的挪威云杉一样容易地选择和定植切割的 Sitka,这会影响其在 Sitka 种植区的建立风险。虽然活的锡特加树的易感性仍不清楚,但该研究促进了对宿主排放的挥发性有机化合物 (VOCs) 在主要宿主位置的作用以及 I. typographus 在宿主选择中的诱导宿主偏好的理解。© 2025 年皇家版权和作者。由John Wiley & Sons Ltd代表化学工业协会出版的《害虫管理科学》。本文经 HMSO 财务总监和苏格兰国王印刷商许可发布。
