Accumulating reports of global bee declines have drawn much attention to the bee microbiota and its importance. Most research has focused on social bees, while solitary species have received scant attention despite their enormous biodiversity, ecological importance, and agroeconomic value. We review insights from several recent studies on diversity, function, and drivers of the solitary-bee microbiota, and compare these factors with those relevant to the social-bee microbiota. Despite basic similarities, the social-bee model, with host-specific core microbiota and social transmission, is not representative of the vast majority of bee species. The solitary-bee microbiota exhibits greater variability and biodiversity, with a strong impact of environmental acquisition routes. Our synthesis identifies outstanding questions that will build understanding of these interactions, responses to environmental threats, and consequences for health.
有关全球蜜蜂数量减少的报告越来越多，这引起了人们对蜜蜂微生物组及其重要性的关注。大多数研究都集中在社会性蜜蜂上，而尽管独居物种具有巨大的生物多样性、生态重要性和农业经济价值，但却很少受到关注。我们综述了最近几项关于独居蜜蜂微生物组多样性、功能和驱动因素的研究，并将这些因素与社会性蜜蜂微生物组的相关因素进行了比较。尽管存在基本相似之处，但具有宿主特异性核心微生物组和社会性传播的社会性蜜蜂模型并不能代表绝大多数蜜蜂物种。独居蜜蜂的微生物组表现出更大的可变性和生物多样性，并且受到环境获取途径的强烈影响。我们的综合分析确定了一些悬而未决的问题，这些问题将有助于人们了解这些相互作用、对环境威胁的反应以及对健康的影响。
