物种迁移到它们的原生地之外是对生物多样性的一个主要威胁.树食昆虫的入侵攻击本地树木和本地昆虫的引进树木的定殖导致新的昆虫-树木关系。到目前为止，影响这些新的相互作用结果的关键因素还不确定。我们报告的结果的荟萃分析346成对比较森林昆虫适合新的和古老的寄主树种从31个出版物。昆虫的寄主特异性和古老寄主树与新寄主树之间的系统发育相关性是影响昆虫适合度的关键因素。总体而言，健身显着低于新的主机物种比古代主机。然而，在某些情况下，健身增加新的主机，主要是在杂食性昆虫或当近亲的古老的主机树殖民。我们的合成可以大大提高生物入侵的影响预测和风险评估。
P>The translocation of species beyond their native range is a major threat to biodiversity. Invasions by tree-feeding insects attacking native trees and the colonization of introduced trees by native insects result in new insect-tree relationships. To date there is uncertainty about the key factors that influence the outcome of these novel interactions. We report the results of a meta-analysis of 346 pairwise comparisons of forest insect fitness on novel and ancient host tree species from 31 publications. Host specificity of insects and phylogenetic relatedness between ancient and novel host trees emerged as key factors influencing insect fitness. Overall, fitness was significantly lower on novel host species than on ancient hosts. However, in some cases, fitness increased on novel hosts, mainly in polyphagous insects or when close relatives of ancient host trees were colonized. Our synthesis enables greatly improved impact prediction and risk assessment of biological invasions.
