熊蜂等入侵物种是一种严重的威胁，可能导致当地生物多样性的下降。我们研究了B的栖息地适宜性。东亚国家陆生蜂入侵的风险和栖息地重叠的风险与24种熊蜂在中国不同的群体。所有东亚国家都被预测为易受B入侵的国家。中国的生境适宜性最高，其次是日本、朝鲜、韩国和蒙古。中国是全球熊蜂生物多样性的热点地区，预计西北、中部至东南和东北三个不同地区非常适合入侵。在中国，与B关系密切的种群。terrestris对与B生境重叠的敏感性较高（89%）。terrestris比非密切相关的物种组（73%）。我国三大区域熊蜂的重叠风险依次为南部地区、北方地区和青藏高原地区。由于栖息地适宜性和重叠的敏感性，使用引进的欧洲熊蜂B。在中国有重叠生境的地区，应劝阻使用土蜂授粉，并应实施管理战略，以保护所有东亚国家脆弱的熊蜂。
Invasive species such as Bombus terrestris represent a severe threat that can result in the decline of local biodiversity. We examined the habitat suitability for B. terrestris invasion in East Asian countries and the risk of habitat overlap with 24 bumblebee species from different groups in China. All East Asian countries were predicted to be susceptible to invasion by B. terrestris, with the highest habitat suitability occurring in China followed by Japan, North Korea, South Korea and Mongolia. Within China, which is a global biodiversity hotspot for bumblebees, three different regions, north-west, central to south-east and north-east, were predicted as being highly suitable for invasion. In China, the group of species closely related to B. terrestris showed higher sensitivity (89%) to habitat overlap with B. terrestris than did the group of non-closely related species (73%). The risk of overlap for the three major regional bumblebees within China decreased in the order southern region, northern region and Tibetan Plateau region. Due to the sensitivity of habitat suitability and overlap, the use of the introduced European bumblebee B. terrestris for pollination services should be discouraged in regions with overlapping habitats in China, and management strategies should be implemented to conserve the vulnerable bumblebees in all East Asian countries.
