入侵的黑胸黄蜂被认为是欧洲和亚洲传粉者的一种日益增长的威胁。虽然这一物种对被管理的蜜蜂的影响已经有了很好的记录，但对其他传粉者种群的影响仍然知之甚少。尽管如此，饮食分析表明，黄蜂捕食的猎物种类繁多，这加剧了人们对濒危分类群的担忧。在这里，我们量化了绒毛弧菌对标准化的商业饲养的欧洲大黄蜂群体的影响。使用景观规模的实验设计，我们在当地绒毛弧菌密度的梯度上部署群体，利用自动跟踪非侵入性观察蜜蜂和大黄蜂的行为，并量化随后对群体结果的影响。我们的结果表明，黄蜂经常在B.terrestris蜂群中捕食，优先被那些觅食流量高的蜂群吸引，并在巢入口处反复进行-但完全不成功的-捕食尝试。然而，值得注意的是，我们发现B.terrestris菌落重量与当地绒毛弧菌密度呈负相关，这表明对菌落生长有潜在的间接影响。综上所述，这些发现首次提供了对群体水平上对大黄蜂的影响的经验性洞察，并为未来野生和管理传粉者的缓解努力提供了信息。入侵的黄蜂对陆地熊蜂群体的影响是沿着黄蜂密度的梯度进行量化的，揭示了对陆地熊蜂群体生长的负面影响。
The invasive hornet Vespa velutina nigrithorax is considered a proliferating threat to pollinators in Europe and Asia. While the impact of this species on managed honey bees is well-documented, effects upon other pollinator populations remain poorly understood. Nonetheless, dietary analyses indicate that the hornets consume a diversity of prey, fuelling concerns for at-risk taxa. Here, we quantify the impact of V. velutina upon standardised commercially-reared colonies of the European bumblebee, Bombus terrestris terrestris. Using a landscape-scale experimental design, we deploy colonies across a gradient of local V. velutina densities, utilising automated tracking to non-invasively observe bee and hornet behaviour, and quantify subsequent effects upon colony outcomes. Our results demonstrate that hornets frequently hunt at B. terrestris colonies, being preferentially attracted to those with high foraging traffic, and engaging in repeated—yet entirely unsuccessful—predation attempts at nest entrances. Notably however, we show that B. terrestris colony weights are negatively associated with local V. velutina densities, indicating potential indirect effects upon colony growth. Taken together, these findings provide the first empirical insight into impacts on bumblebees at the colony level, and inform future mitigation efforts for wild and managed pollinators. The influence of the invasive hornet Vespa velutina on Bombus terrestris colonies is quantified along a gradient of hornet densities, revealing negative impacts upon B. terrestris colony growth.
