The growth of the commercial pollination industry raises important concerns regarding honey bee (Apis mellifera Linnaeus; Hymenoptera: Apidae) health and development. While providing such services, honey bees are often exposed to undiversified pollen sources that may contribute to nutritional deficiencies, notably in protein and amino acids. To understand how honey bees are affected during provision of pollination services, we compared honey bee colonies that pollinated lowbush blueberry (Vaccinium angustifolium Aiton; Ericaceae) and/or cranberry (Vaccinium macrocarpon Aiton; Ericaceae) crops (management strategies) with control colonies in a diversified farmland environment. We identified the floral species of pollen collected by honey bee colonies in those crops compared to pollen collected by control colonies. We also analysed the protein and essential amino acid content of collected pollen and bee bread and measured the nutritional impact of pollination services on honey bee colonies. We found that honey bees providing blueberry and/or cranberry pollination services are exposed to a less diversified pollen diet than colonies located in a farmland environment, especially in a cranberry field. There was a significantly lower proportion of crude protein content in collected and stored pollen during provision of blueberry pollination services, which led to a smaller brood population. Many nutritional deficiencies were measured with regards to essential amino acids.

商业授粉业的发展引起了人们对蜜蜂（蜜蜂）的健康和发展的重要关注。蜜蜂（Apis mellifera Linnaeus；膜翅目：Apidae）在提供此类服务的同时，蜜蜂通常会暴露于未多样化的花粉来源，这可能会导致营养不足，尤其是蛋白质和氨基酸。为了了解蜜蜂在授粉服务过程中受到的影响，我们比较了对低矮丛生蓝莓（越橘）（Vaccinium angustifolium Aiton; Ericaceae）和/或蔓越莓（越橘（Vaccinium macrocarpon））授粉的蜜蜂群体艾顿 在多样化的农田环境中具有控制菌落的Ericaceae）作物（管理策略）。我们确定了与对照菌落采集的花粉相比，蜜蜂在这些农作物中采集的花粉的花种。我们还分析了采集的花粉和蜂面包的蛋白质和必需氨基酸含量，并测量了授粉服务对蜂群的营养影响。我们发现，提供蓝莓和/或蔓越莓授粉服务的蜜蜂所受到的花粉饮食分布要比农田环境中的殖民地少，尤其是在蔓越莓田中。在提供蓝莓授粉服务期间，收集和储存的花粉中粗蛋白含量的比例显着降低，这导致育雏数量减少。
