As part of national biosecurity programs, cargo imports, passenger baggage, and international mail are inspected at ports of entry to verify compliance with phytosanitary regulations and to intercept potentially damaging nonnative species to prevent their introduction. Detection of organisms during inspections may also provide crucial information about the species composition and relative arrival rates in invasion pathways that can inform the implementation of other biosecurity practices such as quarantines and surveillance. In most regions, insects are the main taxonomic group encountered during inspections. We gathered insect interception data from nine world regions collected from 1995 to 2019 to compare the composition of species arriving at ports in these regions. Collectively, 8,716 insect species were intercepted in these regions over the last 25 yr, with the combined international data set comprising 1,899,573 interception events, of which 863,972 were identified to species level. Rarefaction analysis indicated that interceptions comprise only a small fraction of species present in invasion pathways. Despite differences in inspection methodologies, as well as differences in the composition of import source regions and imported commodities, we found strong positive correlations in species interception frequencies between regions, particularly within the Hemiptera and Thysanoptera. There were also significant differences in species frequencies among insects intercepted in different regions. Nevertheless, integrating interception data among multiple regions would be valuable for estimating invasion risks for insect species with high likelihoods of introduction as well as for identifying rare but potentially damaging species.

全球边境拦截为人类介导的全球昆虫运动提供了一个窗口

作为国家生物安全计划的一部分，货物进口、旅客行李和国际邮件在入境口岸接受检查，以验证植物检疫法规的遵守情况，并拦截可能具有破坏性的非本地物种以防止其传入。在检查期间检测生物体还可以提供有关物种组成和入侵途径中相对到达率的重要信息，可以为其他生物安全措施的实施提供信息，例如检疫和监视。在大多数地区，昆虫是检查过程中遇到的主要分类群。我们收集了从 1995 年到 2019 年收集的来自世界九个地区的昆虫拦截数据，以比较到达这些地区港口的物种组成。总共 8, 在过去的 25 年里，这些地区截获了 716 种昆虫物种，综合国际数据集包括 1,899,573 次截获事件，其中 863,972 次被确定为物种级别。稀疏分析表明，拦截仅占入侵途径中存在的一小部分物种。尽管检查方法存在差异，以及进口来源地区和进口商品的构成存在差异，但我们发现地区之间的物种截获频率存在很强的正相关性，特别是在半翅目和缨翅目中。不同地区截获的昆虫的物种频率也存在显着差异。尽管如此，
