全球昆虫传粉者数量的下降危及农业和自然生态系统中授粉服务的提供。传染病在蜜蜂中的重要性已有文献记载，但关于这些疾病在多大程度上与其他传粉目昆虫共有的信息却很少。在此，我们首次证实了食蚜蝇传粉者（双翅目：食蚜蝇科）中存在三种重要的蜜蜂病毒：黑蜂王台病毒（BQCV）、囊状幼虫病毒（SBV）和变形翼病毒B株（DWV - B）。这些病毒在两种蚜蝇属物种中被检测到，它们在行为和形态上都模拟蜜蜂，并与蜜蜂共享觅食生态位。从蚜蝇属物种和西方蜜蜂中分离出的病毒的核苷酸序列，对于这两种病毒来说，相似度分别高达99%和100%，这表明这些病原体在蜜蜂和食蚜蝇之间自由传播。有趣的是，虽然在食蚜蝇中未检测到复制中间体（负链病毒），但SBV的病毒滴度与在西方蜜蜂中发现的相似。这些结果表明，食蚜蝇传粉者可能在传粉者疾病动态中扮演着一个重要但此前未被探索的角色。
Global declines of insect pollinators jeopardize the delivery of pollination services in both agricultural and natural ecosystems. The importance of infectious diseases has been documented in honeybees, but there is little information on the extent to which these diseases are shared with other pollinator orders. Here, we establish for the first time the presence of three important bee viruses in hoverfly pollinators (Diptera: Syrphidae): black queen cell virus (BQCV), sacbrood virus (SBV) and deformed wing virus strain B (DWV-B). These viruses were detected in two Eristalis species, which are behavioural and morphological bee mimics and share a foraging niche with honeybees. Nucleotide sequences of viruses isolated from the Eristalis species and Apis mellifera were up to 99 and 100% identical for the two viruses, suggesting that these pathogens are being shared freely between bees and hoverflies. Interestingly, while replicative intermediates (negative strand virus) were not detected in the hoverflies, viral titres of SBV were similar to those found in A. mellifera. These results suggest that syrphid pollinators may play an important but previously unexplored role in pollinator disease dynamics.
