Abstract

Beetles are commonly moved among continents with international trade. Baited traps set up in and around entry points are commonly used to increase chances of early-detection of incoming species and complement visual inspections. A still underestimated benefit of this surveillance approach is the high number and diversity of collected bycatch species. In this study, we exploited a multiyear surveillance program carried out with baited traps at five Spanish ports and their surrounding natural areas to investigate i) the importance of identifying bycatch to more promptly detect nonnative species belonging to non-target groups; ii) patterns of native and nonnative species richness and abundance inside the port areas vs. surrounding natural areas; iii) the occurrence of spillover events between natural areas surrounding ports and the port areas, and iv) whether the native species most commonly introduced into other countries are more abundant in port areas than in surrounding natural areas. A total of 23,538 individuals from 206 species representing 33 families were collected. The number and taxonomic diversity of the 26 bycatch nonnative beetle species testified that the identification of these unintentionally trapped species can provide additional information on ongoing invasions. Patterns of spillover and native species richness and abundance in port areas vs. surrounding natural areas highlighted a differential ability of different beetle families to colonize port areas. Finally, native species most commonly introduced into other countries were more abundant in port areas than in their surroundings, while the opposite trend occurred for native species that have not been introduced elsewhere. Our study highlighted that the use of traps baited with generic attractants can aid in early-detection of nonnative beetle species, and that the identification of native species can provide useful information on the risk of introduction in other countries.

Investigating入境点内和周围的甲虫群落可以在国家和国际范围内改善监测
甲壳虫通常通过国际贸易在各大洲之间移动。在入境点及其周围设置的诱饵陷阱通常用于增加早期发现外来物种的机会,并补充目视检查。这种监测方法的一个仍然被低估的好处是收集到的副渔获物物种的数量和多样性很高。在这项研究中,我们利用在西班牙五个港口及其周围自然区域使用诱饵陷阱进行的多年监测计划,调查i)识别副渔获物的重要性,以更迅速地检测属于非目标群体的非本地物种;ii)港口区域内与周围自然区域的本地和非本地物种丰富度和丰度模式;iii)港口周围的自然区域和港口地区之间发生的溢出事件,以及iv)最常见地引入其他国家的本土物种在港口地区是否比在周围的自然地区更丰富。共采集了来自33科206种的23538个个体。26种副渔获物非本地甲虫物种的数量和分类多样性证明,识别这些无意捕获的物种可以为正在进行的入侵提供更多信息。港口地区与周围自然地区的溢出模式和本地物种丰富度和丰度突出了不同甲虫科在港口地区定居的不同能力。最后,最常引入其他国家的本土物种在港口地区比在其周围地区更为丰富,而在其他地方没有引入的本土物种则出现了相反的趋势。我们的研究强调,使用以通用引诱剂为诱饵的陷阱有助于早期发现非本土甲虫物种,识别本土物种可以提供有关在其他国家引入风险的有用信息。
