物种的全球迁移和气候变化促进了生物入侵。鉴于入侵可能造成生态和经济破坏，并对生物多样性构成重大威胁，了解入侵成功背后的机制至关重要。无论是释放的非本地人口从天敌，如寄生虫，这些人口的遗传多样性可能发挥关键作用，在他们的入侵成功。我们调查了寄生虫群落的作用，通过敌人释放和寄生虫收购，和遗传多样性的入侵成功的非本地大黄蜂，熊蜂hypnorum，在英国。侵入性B。对于两种高影响寄生虫，hypnorum的寄生虫流行率高于大多数或所有本地同源物，可能是由于更高的易感性和寄生虫获取。因此，寄生虫对B的影响更大。hypnorum queens的生存和殖民地建立的成功比本地物种。在性别决定基因座上，矮熊蜂的功能遗传多样性也低于本地物种。较高的寄生虫流行率和较低的遗传多样性并没有阻止B快速入侵英国。催眠状态这些数据可能会让我们了解世界各地商业熊蜂的类似入侵。这项研究表明，关注寄生虫的影响，共同的小创始人口重新引入和易位程序可能不像目前认为的那么重要。
Biological invasions are facilitated by the global transportation of species and climate change. Given that invasions may cause ecological and economic damage and pose a major threat to biodiversity, understanding the mechanisms behind invasion success is essential. Both the release of non-native populations from natural enemies, such as parasites, and the genetic diversity of these populations may play key roles in their invasion success. We investigated the roles of parasite communities, through enemy release and parasite acquisition, and genetic diversity in the invasion success of the non-native bumblebee, Bombus hypnorum, in the United Kingdom. The invasive B. hypnorum had higher parasite prevalence than most, or all native congeners for two high-impact parasites, probably due to higher susceptibility and parasite acquisition. Consequently parasites had a higher impact on B. hypnorum queens’ survival and colony-founding success than on native species. Bombus hypnorum also had lower functional genetic diversity at the sex-determining locus than native species. Higher parasite prevalence and lower genetic diversity have not prevented the rapid invasion of the United Kingdom by B. hypnorum. These data may inform our understanding of similar invasions by commercial bumblebees around the world. This study suggests that concerns about parasite impacts on the small founding populations common to re-introduction and translocation programs may be less important than currently believed.
