Invasive organisms represent great threats to ecosystems and great challenges to forest management. In Europe, the black timber bark beetle (Xylosandrus germanus) is an invasive secondary pest that mostly attacks the logs of felled trees. We showed the invasion history for Europe and using many local surveys, we summarize the current distribution and other available information on X. germanus in the Czech Republic. We report that this species is distributed from the lowlands to the mountains in the Czech Republic; it is widespread in the eastern half of the country, where it is more abundant in the warmer south and southeast areas than in the cooler areas. Most (78%) of the known localities are at elevation below 400 m a.s.l. Although an ice storm greatly increased X. germanus abundance near the border with Austria, its high abundance did not result in damage to standing trees. Presence of X. germanus in the Czech Republic for over 10 years has not led to heavy tree infestation.

中欧的 Xylosandrus Germanus：在捷克共和国境内和境内传播

入侵生物对生态系统构成巨大威胁，对森林管理构成巨大挑战。在欧洲，黑木皮甲虫 (Xylosandrus Germanus) 是一种侵入性次生害虫，主要攻击砍伐树木的原木。我们展示了欧洲的入侵历史，并使用许多当地调查，我们总结了捷克共和国 X. Germanus 的当前分布和其他可用信息。我们报告说，该物种分布于捷克共和国的低地和山区；它在该国东半部广泛分布，在较温暖的南部和东南部地区比在较冷的地区更为丰富。大多数 (78%) 已知地点的海拔低于 400 m asl 尽管冰暴大大增加了与奥地利边界附近的 X. Germanus 丰度，它的高丰度并没有对立树造成损害。X. Germanus 在捷克共和国的存在已超过 10 年，并没有导致严重的树木侵扰。
