昆虫面临着农业集约化的压力。为了保护传粉者，欧盟农业环境计划(AES)等保护措施鼓励沿着田野种植野花。然而，这可能会通过充当传播枢纽或稀释感染来改变疾病生态。我们通过测量植物-传粉者之间的相互作用和农业景观中传粉者群落一年来的病毒感染(DWV-A、DWV-B和ABPV)来测试这一点。AES对DWV-B有直接影响，降低了蜜蜂的患病率和负荷量，在初夏对负荷量有暂定的一般稀释效应。在AES下，DWV-A的流行率降低了，而且可能通过稀释效应，能力强的寄主之间的生态位重叠增加。相比之下，AES对ABPV没有影响，它的流行是由社区中大黄蜂的比例驱动的。流行病学差异也反映在病毒系统发育上，DWV-B显示出最近的快速扩张，而DWV-A和ABPV显示出较慢的增长速度和地理人口结构。系统发育研究表明，这三种病毒都可以在宿主种群中自由传播。我们的研究阐明了环境、生态和进化因素之间的复杂相互作用如何影响野生动物疾病动态。支持传粉者的营养可以减少重要蜜蜂疾病的传播，为传粉者的保护提供意想不到的促进。本文是“不断变化的世界中的传染病生态和进化”专题的一部分。
Insects are under pressure from agricultural intensification. To protect pollinators, conservation measures such as the EU agri-environment schemes (AES) promote planting wildflowers along fields. However, this can potentially alter disease ecology by serving as transmission hubs or by diluting infections. We tested this by measuring plant–pollinator interactions and virus infections (DWV-A, DWV-B and ABPV) across pollinator communities in agricultural landscapes over a year. AES had a direct effect on DWV-B, reducing prevalence and load in honeybees, with a tentative general dilution effect on load in early summer. DWV-A prevalence was reduced both under AES and with increasing niche overlap between competent hosts, likely via a dilution effect. By contrast, AES had no impact on ABPV, its prevalence driven by the proportion of bumblebees in the community. Epidemiological differences were also reflected in the virus phylogenies, with DWV-B showing recent rapid expansion, while DWV-A and ABPV showed slower growth rates and geographical population structure. Phylogenies indicate that all three viruses freely circulate across their host populations. Our study illustrates how complex interactions between environmental, ecological and evolutionary factors may influence wildlife disease dynamics. Supporting pollinator nutrition can mitigate the transmission of important bee diseases, providing an unexpected boost to pollinator conservation. This article is part of the theme issue ‘Infectious disease ecology and evolution in a changing world’.
