Abstract Solid wood packaging material (WPM) is widely recognized as a high-risk pathway for transport and potential introduction of wood-boring insects, including longhorned beetles in the family Cerambycidae. These beetles also are occasionally imported in finished wood products, such as furniture and decorative items. A targeted effort to identify wood borers intercepted as larvae in WPM at U.S. ports between 2012 and 2018 revealed that one of the most frequently intercepted species was Trichoferus campestris (Faldermann), a cerambycid native to Asia. Trichoferus campestris is a pest of quarantine concern in the United States, Canada, and Europe. The establishment risk of this beetle in the United States is high because of its frequent introduction through multiple pathways and its potential to inhabit natural and urban forests as well as agricultural systems. In this study, we compiled port interception and detection data to examine risk based on historical introductions and pathways. We tested whether the intended destination of cargo intercepted with T. campestris-infested WPM can be used as a predictor of inland introductions, assuming that individuals of T. campestris are likely to be moved through established trade routes between export–import partners. We also developed maps to predict likely areas of introduction and establishment in the United States based on pathway analysis and climate suitability data. The maps will enable informed prioritization of resources in pest surveillance, and may serve as models for other wood borers identified in the WPM and wood products pathway.

预测侵入性蛀木甲虫 Trichoferus campestris（鞘翅目：天牛科）在美国的定殖潜力

摘要 实木包装材料 (WPM) 被广泛认为是运输和潜在引入蛀木昆虫的高风险途径，包括天牛科的长角甲虫。这些甲虫偶尔也会在成品木制品中进口，例如家具和装饰品。一项旨在确定 2012 年至 2018 年间在美国港口的 WPM 中作为幼虫拦截的蛀木虫的有针对性的努力表明，最常拦截的物种之一是 Trichoferus campestris (Faldermann)，这是一种原产于亚洲的天牛。Trichoferus campestris 是一种在美国、加拿大和欧洲受到检疫的害虫。这种甲虫在美国的定殖风险很高，因为它通过多种途径频繁引入，并且有可能栖息在自然和城市森林以及农业系统中。在本研究中，我们汇编了端口拦截和检测数据，以根据历史介绍和路径检查风险。我们测试了被 T. campestris 感染的 WPM 拦截的货物的预期目的地是否可以用作内陆引入的预测指标，假设 T. campestris 个体可能通过进出口伙伴之间的既定贸易路线移动。我们还开发了地图，以根据路径分析和气候适宜性数据预测美国可能的引入和建立区域。
