Native and non-native insect herbivores associated with native and non-native European trees

We compiled a list of all native and non-native insect species known to feed on 77 tree species in Europe. For each tree species, a list of insects known to utilize that species as a host was compiled using a variety of sources. The resulting list consists of 7,598 tree species -insect species pairs. Each insect was researched to determine its taxonomic groupings, feeding guild (gall-maker, folivore, reproductive plant feeder, sap-feeder, or phloem/wood-borer), and whether it was native to Europe or non-native.

本研究整理了欧洲地区已知以77种树木为寄主的全部本土与非本土昆虫物种名录。针对每一种目标树木，研究团队通过多类数据源编制了以该树木为寄主的昆虫物种名录。最终构建的数据集共包含7598组树木-昆虫物种配对。研究人员对每一种昆虫开展系统性调研，以明确其分类类群、取食功能群（feeding guild）——涵盖造瘿昆虫（gall-maker）、食叶昆虫（folivore）、植物繁殖器官取食昆虫（reproductive plant feeder）、树液取食昆虫（sap-feeder）以及韧皮部/木质部蛀干昆虫（phloem/wood-borer）——同时确定该昆虫是否为欧洲本土物种或非本土物种。
