今天，我们分享1则消息和3篇文章。 1.受肺炎疫情影响推迟举办小蠹学术研讨培训班；2.分类学专家在建立DNA数据库中的作用；3.气候变化对韩国橡树枯萎病的影响 4. 澳洲桉叶甲在亚洲的首次记录
Bark Beetle Academy – Postponement
Unfortunately, the COVID-19 virus has continued to cause disruptions and we have been forced to postpone the Academy event due to take place in Taiwan on May 4-8th. We are in the process of re-arranging the event for Spring 2021. For more details please see the website.
受新冠肺炎疫情的影响，原定于今年5月4日至8日在台湾的小蠹学术研讨培训班活动将推迟举行。我们可能会将新的时间定在2021年春季。更多详情请关注官网。

The Essential Role of Taxonomic Expertise in the Creation of DNA Databases for the Identification and Delimitation of Southeast Asian Ambrosia Beetle Species (Curculionidae: Scolytinae: Xyleborini)
生物分类学专业知识在建立东南亚食菌小蠹DNA数据库进行物种鉴定和界定中的重要作用
Cognato, A., Sari, G., Smith, S., Beaver, R., Li, Y., Hulcr, J., Jordal, B., Kajimura, H., Lin, CS., Pham, TH., Singh, S., Sittichaya, W. – Frontiers in Ecology and Evolution
DNA holds great potential for species identification and efforts to create a DNA database of all animals and plants currently contains >7.5 million sequences representing ~300,000 species. This promise of a universally applicable identification tool suggests that morphologically based tools and taxonomists will soon not have utility. Here we demonstrate that DNA-based identification is not reliable without the contributions of taxonomic experts. We use ambrosia beetles (Xyleborini), which are known for great diversity as well as global invasions and damage, as a test case. Recent xyleborine introductions have caused major economic and ecological losses, thus timely species identifications of new invaders are necessary. The involvement of taxonomic experts from the start of this project was essential for the creation of a stable foundation for the DNA identification of xyleborine species. In general, their role in DNA barcoding cannot be underestimated and is further discussed.
DNA在物种识别方面具有巨大潜力，用于目前创建所有动植物的DNA数据库包含750万个代表约30万个物种的序列。这种普适的物种识别工具的应用前景曾表明，基于形态学的分类工具和分类学家很快将不再有用武之地。而本文则证明了没有分类专家的帮助，仅基于DNA的鉴定是不可靠的。我们以多样性高及全球入侵和破坏力强的材小蠹（Xyleborini）作为案例。新入侵的材小蠹类造成了重大的经济和生态损失，因此有必要对新入侵者及时进行物种鉴定。分类学专家的参与对于该项目起到了决定性的左右，为材小蠹物种的DNA鉴定奠定了坚实的基础。他们对DNA条形码的作用的影响不能被低估，他们角色也需要重新审视。

Climate Change Impacts on Forest Management: A Case of Korean Oak Wilt
气候变化对森林管理的影响：以韩国橡树枯萎病为例
An, H., Lee, S., Cho, SJ. – Climate
Climate change is expected to affect the occurrence of forest pests. This study depicts a method to measure the impact of damage inflicted by a forest pest like oak wilt as a result of climate change. We determine the damage function considering the factors related to the pest damage and forecast the future damage rate under future climate change. The results show that the damage rate and the affected area from oak wilt would increase under climate change. In addition, the economic evaluation indicates that an altered climate would reduce the management returns and increase uncertainty. However, these outcomes could be alleviated by carrying out the control and prevention measures after the infection occurs.
气候变化将影响森林有害生物的发生。该项研究对一种用于测量气候变化对虫害引起的病害（橡树枯萎病）所造成的森林损害影响程度的方法进行了描述。通过几组与有害生物损害相关的因素来确定损害函数，并预测了未来气候变化下的未来损害率变化。结果表明，随着气候变化，橡树枯萎病的危害率和受灾面积将增加。此外，经济评估表明，气候变化将降低管理收益并增加不确定性因素。但采取对控制和预防措施可以减轻这些后果。

First report of the invasive Australian tortoise beetle Trachymela sloanei (Coleoptera: Chrysomelidae: Chrysomelinae) in Asia
澳洲桉叶甲在亚洲的首次记录
Zhang, M., Chen, X., Ruan, Y., Jiang, S., Yang, J., Jiang, M., Ruan, X., Li, Y. – Journal of Asia-Pacific Entomology
The Australian tortoise beetle Trachymela sloanei (Coleoptera: Chrysomelidae: Chrysomelinae), an invasive pest of several species of Eucalyptus has been reported for the first time in Asia. It was first detected in Shenzhen, China where it has become established. Currently, T. sloanei is not a destructive forest pest in Shenzhen. Pupae and adults were frequently found infected by an unknown fungus.
澳洲桉叶甲是一种入侵性很强的桉树害虫，之前已经入侵了美国和新西兰，这是首次报道其在亚洲发生。发现于我国广东深圳。当前在我国，该害虫已定殖，但并未有大面积为害。其成虫和蛹常被发现遭受一种未知真菌的侵染。
