Abstract

Honey bee propolis is a complex, resinous mixture created by bees using plant sources such as leaves, flowers, and bud exudates. This study characterized how cropland surrounding apiaries affects the chemical composition and antimicrobial effects of propolis. The chemical composition and compound abundance of the propolis samples were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) and the antimicrobial effects were analyzed using the 50% minimum inhibitory concentration (MIC) assay against four relevant bee pathogens, and . Propolis composition varied significantly with apiary, and cropland coverage predicted mean sum abundance of compounds. The apiary with the highest cropland coverage exhibited significantly higher MIC values for and compared to other apiaries. These results demonstrate that agricultural land use surrounding honey bee apiaries decreases the chemical quality and antimicrobial effects of propolis, which may have implications for the impacts of land use on hive immunity to potential pathogens.

摘要

蜜蜂蜂胶是蜜蜂利用树叶、花朵和芽渗出物等植物来源制成的一种复杂的树脂混合物。本研究描述了养蜂场周围的农田如何影响蜂胶的化学成分和抗菌效果。使用气相色谱-质谱联用仪（GC-MS）分析蜂胶样品的化学成分和化合物丰度，并使用针对四种相关蜜蜂病原体的50%最低抑菌浓度（MIC）测定法分析抗菌效果。蜂胶成分因养蜂场而异，农田覆盖率可预测化合物的平均总丰度。与其他养蜂场相比，农田覆盖率最高的养蜂场对和的MIC值显著更高。这些结果表明，蜜蜂养蜂场周围的农业土地利用降低了蜂胶的化学质量和抗菌效果，这可能对土地利用对蜂巢对潜在病原体的免疫力的影响具有启示意义。
