Occurrence of black queen cell virus in wild bumble bee communities in China

Wild bumble bees (Hymenoptera: Apidae) play a vital role in agro-ecosystems as important pollinators. However, they are threatened by virus pathogens that are widespread in honey bees.

Description
Summary:Wild bumble bees (Hymenoptera: Apidae) play a vital role in agro-ecosystems as important pollinators. However, they are threatened by virus pathogens that are widespread in honey bees. Previous studies have reported that viruses were able to be transmitted across bee genera and caused potential danger to wild bumble bees. China is a global biodiversity hotspot for bumble bees. However, the impact of viruses on the wild bumble bee communities remains elusive. Black queen cell virus (BQCV) is one of the most common honey bee viruses. Here, a total of 72 wild bumble bee samples from 17 geographic regions of China were tested for BQCV. Thirteen positive samples were identified and sequence comparison of partial capsid genes demonstrated a genetic identity of 99.69% to 100%. A phylogenetic tree analysis also showed a close relationship between 13 BQCV isolates and others from a variety of recorded hosts in China. Meanwhile, a distinct evolutionary branch of China isolates was formed when clustering isolates from worldwide bumble bee species. A correlation between BQCV and their geographic locations were observed (P < 0.05).This study not only provides the first evidence of widespread BQCV in wild bumble bee communities in China but also detects a distinct set of genetically identical or closely related BQCV variants that circulate and evolutionarily differ from other countries.
