蜜蜂是重要的农作物传粉者。自2006年以来，美国养蜂人经历了每年高的蜂群损失，这可能归因于包括病原体在内的多种非生物和生物因素。然而，这些因素的相对重要性还没有完全阐明。为了确定最流行的病原体并调查蜂群强度与健康之间的关系，我们评估了参与杏仁授粉的美国西部蜜蜂群体中病原体的发生、流行和丰度。最常见的病原体是黑皇后细胞病毒(BQCV)、西奈湖病毒2(LSV2)、萨克布鲁德病毒(SBV)、脑微孢子虫和锥虫。结果表明，病原菌的流行率和丰度与采样日期和养蜂操作有关，杏仁授粉后立即采集的蜜蜂样品的病原菌流行率最高，弱蜂群的平均病原菌流行率高于强蜂群。本文的在线版本(doi：10.1007/s13592-0150395-5)包含补充材料，授权用户可以使用。
Honey bees are important pollinators of agricultural crops. Since 2006, US beekeepers have experienced high annual honey bee colony losses, which may be attributed to multiple abiotic and biotic factors, including pathogens. However, the relative importance of these factors has not been fully elucidated. To identify the most prevalent pathogens and investigate the relationship between colony strength and health, we assessed pathogen occurrence, prevalence, and abundance in Western US honey bee colonies involved in almond pollination. The most prevalent pathogens were Black queen cell virus (BQCV), Lake Sinai virus 2 (LSV2), Sacbrood virus (SBV), Nosema ceranae, and trypanosomatids. Our results indicated that pathogen prevalence and abundance were associated with both sampling date and beekeeping operation, that prevalence was highest in honey bee samples obtained immediately after almond pollination, and that weak colonies had a greater mean pathogen prevalence than strong colonies.
