Invasive populations of small spruce bark beetle Ips amitinus were first registered in 2019 in the southeast of Western Siberia. In natural stands of Siberian pine (Pinus sibirica Du Tour), several hundred hectares of outbreak foci of the alien bark beetle were identified. In 2020, a local focus of the bark beetle was found in the conifer collection in the arboretum “Kedr” of the Institute of Monitoring Climatic and Ecological Systems SB RAS, 30 km from Tomsk. The bark beetle caused the main damage to the collection of pines. I. amitinus colonized both host plants Scotch pine (Pinus sylvestris L.) and mountain pine (Pinus mugo Turra), which were previously known to it in the native range in Europe, and the local Siberian species Siberian pine (Pinus sibirica Du Tour), Siberian spruce (Picea obovata Ledeb.) and introduced Far Eastern Korean pine (Pinus koraiensis Sieb. et Zucc.). Demographic characteristics of I. amitinus studied on damaged trees indicate its high reproduction potential in Siberia. The bark beetle outbreak focus was suppressed; however, this plantation requires further annual monitoring of pest abundance and distribution, both to preserve the scientific dendroecological field station and to study the implementation of sential plant conception in relation to the invasion of I. amitinus.

小云杉的树皮甲虫Ips amitinus的入侵种群于2019年在西西伯利亚的东南部首次登记。在西伯利亚松（Pinus sibirica Du Tour）的天然林中，发现了数百公顷外来树皮甲虫的疫源地。2020年，在距托木斯克30公里的气候与生态系统监测研究所SB RAS的植物园“ Kedr”的针叶树中发现了树皮甲虫的局部特征。树皮甲虫对松树的收集造成了主要损害。I. amitinus定居在寄主植物苏格兰松（Pinus sylvestris L.）和山松（Pinus mugoTurra），以前在欧洲的本地范围内都广为人知，还有当地的西伯利亚物种西伯利亚松（Pinus sibirica Du Tour），西伯利亚云杉（Picea obovata Ledeb。），并引入了远东朝鲜松（Pinus koraiensis Sieb。等） Zucc。）。人口特征I.  amitinus研究了受损的树木表明在西伯利亚的高繁殖潜力。树皮甲虫的爆发重点受到抑制；但是，这种人工林需要对虫害的丰度和分布进行进一步的年度监测，以保护科学的树状生态学野外观测站，并研究与艾米氏假单胞菌入侵有关的重要植物概念的实施。
