病原体和寄生虫对蜜蜂物种的健康和福祉构成重大威胁，蜜蜂物种是全世界农作物和花卉的主要传粉者。我们在中国开展了一项全国性的调查，以确定亚洲蜜蜂（Apis cerana）中病原体和寄生虫的发生和流行情况。我们的研究提供了蜜蜂感染致病性变形翼病毒（DWV）、黑蜂后细胞病毒（BQCV）、蜜蜂小蜂和蜂蜂物种的证据，这些物种与欧洲蜜蜂、蜜蜂和大黄蜂的种群下降有关。然而，在蜜蜂中引起广泛感染的DWV病毒的流行率很低，这可能是由于蜜蜂对DWV的有效载体异蚊瓦螨（Varroa destructor）具有更强的抵抗力。对蜜蜂消化道微生物群落的分析表明，小虫感染可能对肠道微生物群产生不利影响。被ceranae感染的工人往往有较低的细菌数量，这些差异在双歧杆菌和巴氏杆菌群中是显著的。这项全国范围的筛选结果表明，在欧洲蜜蜂中造成严重问题的寄生虫和病原体可以在亚洲饲养的本地蜜蜂物种中找到。由于新的农业实践和全球化造成的环境变化可能促进病原体向新的地理区域传播。地理位置接近的传粉媒介的觅食行为可能在寄生虫和病原体传播到新宿主的过程中发挥了重要作用。系统发育分析提供了对这些寄生虫的运动和种群结构的见解，表明寄生虫在传粉媒介之间的双向流动。这些寄生虫和病原体的存在可能对观察到的亚洲蜜蜂数量下降有相当大的影响。
Pathogens and parasites represent significant threats to the health and well-being of honeybee species that are key pollinators of agricultural crops and flowers worldwide. We conducted a nationwide survey to determine the occurrence and prevalence of pathogens and parasites in Asian honeybees, Apis cerana, in China. Our study provides evidence of infections of A. cerana by pathogenic Deformed wing virus (DWV), Black queen cell virus (BQCV), Nosema ceranae, and C. bombi species that have been linked to population declines of European honeybees, A. mellifera, and bumble bees. However, the prevalence of DWV, a virus that causes widespread infection in A. mellifera, was low, arguably a result of the greater ability of A. cerana to resist the ectoprasitic mite Varroa destructor, an efficient vector of DWV. Analyses of microbial communities from the A. cerana digestive tract showed that Nosema infection could have detrimental effects on the gut microbiota. Workers infected by N. ceranae tended to have lower bacterial quantities, with these differences being significant for the Bifidobacterium and Pasteurellaceae bacteria groups. The results of this nationwide screen show that parasites and pathogens that have caused serious problems in European honeybees can be found in native honeybee species kept in Asia. Environmental changes due to new agricultural practices and globalization may facilitate the spread of pathogens into new geographic areas. The foraging behavior of pollinators that are in close geographic proximity likely have played an important role in spreading of parasites and pathogens over to new hosts. Phylogenetic analyses provide insights into the movement and population structure of these parasites, suggesting a bidirectional flow of parasites among pollinators. The presence of these parasites and pathogens may have considerable implications for an observed population decline of Asian honeybees.
