大量开花作物(MFC)被越来越多地种植，并可能影响MFC田地和附近半自然栖息地的传粉者群落。在六个欧洲地区和两年的时间里，我们评估了景观尺度的MFC覆盖如何影响408个MFC田地和邻近SNH的传粉者密度。在MFC农田中，大黄蜂、孤蜂、管理蜜蜂和飞蝇的密度与MFC在景观中的盖度呈负相关。在SNHs中，随着MFC覆盖度的增加，熊蜂的密度下降，而蜜蜂的密度增加。所有传粉者的密度总体上与景观中SNH的盖度无关。尽管MFC田地显然吸引了来自SNH的传粉者，但在MFC面积较大的地区，它们被稀释了。由此导致的较低密度可能会对授粉者依赖型作物的产量和野生植物的繁殖成功产生负面影响。在扩大MFC的同时，需要在农业景观中采取支持传粉者的做法。
Mass‐flowering crops (MFCs) are increasingly cultivated and might influence pollinator communities in MFC fields and nearby semi‐natural habitats (SNHs). Across six European regions and 2 years, we assessed how landscape‐scale cover of MFCs affected pollinator densities in 408 MFC fields and adjacent SNHs. In MFC fields, densities of bumblebees, solitary bees, managed honeybees and hoverflies were negatively related to the cover of MFCs in the landscape. In SNHs, densities of bumblebees declined with increasing cover of MFCs but densities of honeybees increased. The densities of all pollinators were generally unrelated to the cover of SNHs in the landscape. Although MFC fields apparently attracted pollinators from SNHs, in landscapes with large areas of MFCs they became diluted. The resulting lower densities might negatively affect yields of pollinator‐dependent crops and the reproductive success of wild plants. An expansion of MFCs needs to be accompanied by pollinator‐supporting practices in agricultural landscapes.
