Viral infection damages honeybee colony health. Viruses can be carried by queen bees and apicultural production materials when imported from foreign countries. We investigated seven honeybee viruses in worker bees (Apis mellifera) from 26 healthy apiaries in Gifu, Japan between 2018 and 2019. Black queen cell virus (BQCV) was detected in 23 (88.5%) of the apiaries, followed by Israeli acute paralysis virus (42.3%), deformed wing virus (DWV) (38.5%), and sacbrood virus (3.8%). In phylogenetic analysis, BQCV and DWV in Gifu were related to those in China and South Korea. Additionally, a high prevalence of BQCV was observed among worker bees in BQCV-positive colonies. Therefore, BQCV horizontal transmission among worker bees may contribute to the high prevalence of BQCV in Gifu.
病毒感染会损害蜜蜂群体的健康。当从国外进口蜂王和养蜂生产材料时，病毒可能会随之传入。我们调查了 2018 年至 2019 年期间来自日本岐阜县 26 个健康蜂群中工蜂（Apis mellifera）中的 7 种蜜蜂病毒。在 23 个蜂群（88.5%）中检测到了黑蜂王细胞病毒（BQCV），其次是以色列急性麻痹病毒（42.3%）、变形翅膀病毒（DWV）（38.5%）和囊状幼虫病病毒（3.8%）。在系统发育分析中，岐阜县的 BQCV 和 DWV 与中国和韩国的病毒有关。此外，在 BQCV 阳性蜂群中的工蜂中观察到 BQCV 的高流行率。因此，工蜂之间的 BQCV 水平传播可能导致 BQCV 在岐阜县的高流行率。
