长林小蠹Hylurgus ligniperda (Fabricius) 属树皮小蠹类害虫，通常为害新伐木、伐桩、衰弱木，入侵性十分强。长林小蠹原产欧洲、俄罗斯和地中海地区，目前已成功入侵南非、日本、韩国、斯里兰卡、澳大利亚、新西兰、美国、巴西、乌拉圭、智利等地。值得一提的是，关于长林小蠹在东亚地区的分布，文献记录显得比较混乱。比如Wood and Bright 1992年在其专著《A catalog of Scolytidae and Platypodidae (Coleoptera), Part 2. Taxonomic Index》中记录长林小蠹在日本和中国“Manchuria”有分布，而CABI则将中国（广东）列为原产地，同时记录日本是被入侵的。
The red-haired pine bark beetle, Hylurgus ligniperda (Fabricius), is a well-known forest insect that colonizes the phloem of pine species. It can attack stumps, freshly cut logs, and timber. Previously, when researchers studied the original distribution, it included Europe, Russia, the Mediterranean area, and the nearby Atlantic Ocean islands. It was also reported as introduced to South Africa, Japan, South Korea, Sri Lanka, Australia, New Zealand, USA (New York and California), Brazil, Uruguay, and Chile. It should be noted that the distribution of H. ligniperda in East Asia is ambiguous in literature. Wood and Bright (1992) recorded the distribution of H. ligniperda as “Asia (‘Manchuria’ in China/ Japan)”. CABI listed that “native to Asia (China (Guangdong))” and invasive in Japan
在中国，我们于2019年8月首次在山东徂徕山采集到了长林小蠹，其后于2019-2021年多次在山东泰安、烟台和威海采集到长林小蠹。在查阅了国内外文献和检视了中国各地的标本后，我们意识到，中国此前并没有长林小蠹的分布记录，至于广东，也仅仅是有口岸截获的记录。因此，Wood and Bright以及CABI的记录可能有误。
In China, we first collected this bark beetle in August 2019 in Culai Mt.,Shandong Province, and then found more in Tai’an, Yantai, and Weihai of Shandong Province from 2019 to 2021. After reviewing the literature and examining the specimens from different parts of China, we realized that there was no official record of the distribution of H. ligniperda in China before, and as for Guangdong, there was only one record of intercepting of H. ligniperda at the port. Therefore, the records of Wood and Bright and CABI may be incorrect. What does this mean? We do not know whether H. ligniperda is native to Asia or is an invader.
为了摸清东亚地区究竟是长林小蠹的原产地还是被入侵地，作者与来自韩国、日本、美国的小蠹研究学者进行合作，参考长林小蠹在中国、韩国和日本的文献资料和林间调查数据，得出了一些初步的结论。
In order to figure out whether East Asia is the origin or the invaded area of H. ligniperda, the authors cooperated with H. ligniperda researchers from Korea, Japan and the United States, and draws some preliminary conclusions by referring to the literature and forest survey data of H. ligniperda in China, Korea and Japan.
- 在东亚地区，日本是长林小蠹最早入侵的地区，1935年就有发生记录，目前已扩散至本州所有区域。
- 韩国的首个记录是在1999年，目前也扩散至韩国全境。
- 在中国，目前长林小蠹已成功入侵中国山东，此前的分布记录很可能是错误的。而分布地“广东”的记录更是无据可考，我们认为可能是因为“Manchuria（满洲里）”在中国被称为“关东”，其读音与“广东”很容易混淆导致产地错误的引用。
1、 In East Asia, Japan is the first area invaded by H. ligniperda, which was recorded in 1935 and its distribution has covered the entirety of Honshu Island due to decades of colonization..
2、In South Korea, it has spread rapidly in recent years, and its current distribution effectively covers the majority of South Korea.
3、 In China, it has recently invaded and successfully colonized parts of Shandong Province. Investigation and analysis showed that the previous record of the occurrence of H. ligniperda in China was likely misplaced. “Manchuria” has also been called “Guandong” in Chinese. We speculate that this is the origin of the CABI’s misquotation “Guangdong is present”, because there is no record of the occurrence of H. ligniperda in “Guangdong” in the CABI reference list and other literature.
