Several European and Mediterranean species of pine bark beetles (Coleoptera: Curculionidae: Scolytinae) have become established in North America and the southern hemisphere, posing a novel threat to planted and naturally-occurring pine forests. Our objectives were to investigate (1) the occurrence and relative abundance of pine bark beetles in these regions, and (2) the trapping performance of different blends of multispecies lures. In 2016–2017 a network of interception traps was installed in six non-European countries (Argentina, Australia, New Zealand, South Africa, the United States, and Uruguay), and in six European countries (France, Greece, Hungary, Italy, Portugal, and Spain) for comparison. Half of the traps were baited with alpha-pinene and ethanol, and the other half with alpha-pinene, ethanol, and a combination of bark beetle pheromones (ipsdienol, ipsenol, and Z-verbenol). Five Mediterranean scolytine species (Hylurgus ligniperda, Hylastes ater, H. angustatus, Orthotomicus erosus, and O. laricis) were found in non-European countries. Hylurgus ligniperda and Hylastes ater were the most widespread species found in several of the invaded regions, while O. laricis and H. angustatus occurred only in Argentina and South Africa, respectively. Despite large variation among species and countries, most species were trapped with the blend containing bark beetle pheromones, except O. erosus, which was more attracted to alpha-pinene and ethanol alone. This study represents the first step towards the development of an international monitoring protocol based on multi-lure traps for the survey and early-interception of invasive alien bark beetle species.

欧洲和地中海的几种松树皮甲虫（鞘翅目：Curculionidae：Scolytinae）已在北美和南半球建立，对人工种植和天然存在的松树林构成了新的威胁。我们的目标是调查（1）这些地区松树皮甲虫的发生和相对丰度，以及（2）不同种类的多物种诱饵的诱捕性能。2016-2017年，在六个非欧洲国家（阿根廷，澳大利亚，新西兰，南非，美国和乌拉圭）和六个欧洲国家（法国，希腊，匈牙利，意大利，葡萄牙和西班牙）进行比较。一半的诱捕器用α-pine烯和乙醇诱捕，另一半用α-pine烯，乙醇，以及树皮甲虫信息素（ipsdienol，ipsenol和Z-verbenol）的组合。五种地中海苦ly鱼种（在非欧洲国家发现了Hylurgus ligniperda，Hylastes ater，H. angustatus，Orthotomicus erosus和O. laricis）。Hylurgus ligniperda和Hylastes ater是在几个受侵害地区发现的最广泛的物种，而O. laricis和H. angustatus仅分别发生在阿根廷和南非。尽管物种和国家之间差异很大，但大多数物种仍被含有树皮甲虫信息素的混合物所捕获，除了O. erosus，更受α-pine烯和乙醇的吸引。这项研究代表了迈向基于多诱捕器的国际监测协议发展的第一步，该协议用于调查和早期拦截外来入侵性树皮甲虫物种。
