授粉服务受到景观环境、农业管理和传粉者群落结构的影响，所有这些都会影响访花率、花粉沉积和最终产量。我们在阿根廷研究了高丛蓝莓作物的这些过程，这些作物依赖于授粉者来产生可销售的产量。
我们研究了土地覆盖和蜜蜂放养如何影响蓝莓作物中野生和管理传粉者的丰度，使用结构方程模型来解开传粉者对蓝莓果实数量，大小，营养成分和总产量的级联效应。
所有传粉者功能群在1000米以下的空间尺度上对景观变化做出反应，并且影响的意义或方向受到蜂巢实地部署的调制。
果实直径随花粉沉积量的增加而增大，随蜜蜂数量的增加而减小，这对果实酸度有间接影响。蜜蜂对植物产生的果实数量有积极的影响，并通过对果实生产的质量和数量组成部分的独立影响而使总产量（kg植物-1）受益。
合成与应用。在蓝莓田部署蜂箱可以缓冲，但不能补偿周围大规模不开花作物对蜜蜂数量产生的负面影响。这种补偿需要高质量的蜂箱，通过监测它们的健康和强度。蜜蜂对作物生产的贡献在不同的生产指标中是不相等的。也就是说，蜜蜂数量的增加增加了浆果的产量，但代价是更小、更酸的水果，可能会降低它们的市场价值。种植者在积极管理蜜蜂数量时必须考虑水果数量和质量之间的权衡。
Pollination services are affected by landscape context, farming management and pollinator community structure, all of which impact flower visitation rates, pollen deposition and final production. We studied these processes in Argentina for highbush blueberry crops, which depend on pollinators to produce marketable yields.
We studied how land cover and honeybee stocking influence the abundance of wild and managed pollinators in blueberry crops, using structural equation modelling to disentangle the cascading effects through which pollinators contribute to blueberry fruit number, size, nutritional content and overall yield.
All pollinator functional groups responded to landscape changes at a spatial scale under 1000 m, and the significance or direction of the effects were modulated by the field‐level deployment of honeybee hives.
Fruit diameter increased with pollen deposited, but decreased with honeybee abundance, which, had indirect effects on fruit acidity. Honeybees had a positive effect on the number of fruit produced by the plants and also benefited the overall yield (kg plant−1) through independent effects on both the quality and quantity components of fruit production.
Synthesis and applications. Deployment of beehives in blueberry fields can buffer, but not compensate for the negative effects on honeybee abundance produced by surrounding large scale none‐flowering crops. Such compensation would require high‐quality beehives by monitoring their health and strength. The contribution of honeybees to crop production is not equal across production metrics. That is, higher abundance of honeybees increases the number of berries produced but at the cost of smaller and more acidic fruits, potentially reducing their market value. Growers must consider this trade‐off between fruit quantity and quality when actively managing honeybee abundance.
