Abstract

Black locust is the only host of Robinia-specialist insects in Europe. However, no study to date has examined future range shifts of specialist insects, and the relative effects of host plant availability and other factors on their range shifts. Here, we characterized the future range shifts in the host and its four specialist insects and the factors contributing to changes in their ranges. We detected substantial range expansions in all target species. Climate predictors and host plant availability were expected to have the strongest effects on the range shifts in the host and its specialist insects, respectively, suggesting that the specialist insects will track the ranges of their host. Parectopa robiniella showed the largest potential and expanding ranges and should be made a priority species for controlling invasions of Robinia-specialist insects in Europe. The expanding ranges of all specialist species were largely identified in the United Kingdom, Germany, and France, suggesting that these should be priority regions for mitigating their effects on ecosystems. Reducing future climate change is essential for preventing the spreading of specialist insects in Europe since specialist insects track their specialist host plants, and host range expansions are mainly driven by future climate changes.

一棵寄主树和它的特化昆虫：黑刺槐的可利用性在很大程度上决定了其在欧洲的专性昆虫的未来分布范围。

黑刺槐是欧洲刺槐专性昆虫的唯一寄主。然而，迄今为止还没有研究探讨过专性昆虫未来的活动范围变化，以及寄主植物的可利用性和其他因素对其活动范围变化的相对影响。在这里，我们描述了寄主及其四种专性昆虫未来活动范围的变化，以及导致其活动范围变化的因素。我们发现所有目标物种的分布范围都有大幅扩展。气候预测因素和寄主植物的可利用性预计将分别对寄主及其专化昆虫的分布范围变化产生最大影响，这表明专化昆虫将追踪寄主的分布范围。刺槐属昆虫显示出最大的潜在和不断扩大的分布范围，应作为控制欧洲刺槐属专化昆虫入侵的优先物种。在英国、德国和法国，所有专门物种的分布范围都在不断扩大，这表明这些地区应成为减轻其对生态系统影响的优先地区。减少未来气候变化对防止欧洲特化昆虫的传播至关重要，因为特化昆虫会追踪其特化寄主植物，而寄主范围的扩大主要受未来气候变化的驱动。

期刊介绍： Insects (ISSN 2075-4450) is an international, peer-reviewed open access journal of entomology published by MDPI online quarterly. It publishes reviews, research papers and communications related to the biology, physiology and the behavior of insects and arthropods. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
