西方蜜蜂具有重要的经济和生态价值，在过去的20年里，温带地区蜂群损失率的上升被认为主要是由外来的体外寄生粉尘螨瓦罗亚破坏者和变形翅膀病毒(DWV)引起的，这种粉尘螨是由这种粉尘螨传播的。DWV目前以两种主要的基因类型存在：以前流行的DWV-A和最近被描述并迅速扩大的DWV-B。这是一个很好的系统来了解病毒的进化和一个病毒变异被另一个病毒变异所取代。在这里，我们综合了2008-2021年期间发表的关于DWV-A和-B的分布和流行的结果，并提供了德国、意大利和英国的新数据，以表明：(I)自2004年首次描述以来，DWV-B在全球范围内迅速传播，(Ii)它有可能取代DWV-A。在野生蜜蜂物种中也发现了这两种基因。基于一个简单的数学模型，我们认为，当共同感染同一宿主时，病毒基因型之间的干扰是了解它们的流行病学的关键。最后，我们讨论了基因替换对养蜂业和野生授粉物种的影响。白纹伊蚊携带的DWV是蜜蜂蜂群损失的主要原因。在欧洲，DVB型在很大程度上取代了DVA型。目前，除澳大利亚外，DWV B型病毒在世界范围内传播。重组解体可能解释了为什么B型取代了A型。用DwV-B取代DwV-A可能会加剧菌落损失和病原体溢出。
The western honey bee (Apis mellifera) is of major economic and ecological importance, with elevated rates of colony losses in temperate regions over the last two decades thought to be largely caused by the exotic ectoparasitic mite Varroa destructor and deformed wing virus (DWV), which the mite transmits. DWV currently exists as two main genotypes: the formerly widespread DWV-A and the more recently described and rapidly expanding DWV-B. It is an excellent system to understand viral evolution and the replacement of one viral variant by another. Here we synthesise published results on the distribution and prevalence of DWV-A and -B over the period 2008–2021 and present novel data for Germany, Italy and the UK to suggest that (i) DWV-B has rapidly expanded worldwide since its first description in 2004 and (ii) that it is potentially replacing DWV-A. Both genotypes are also found in wild bee species. Based on a simple mathematical model, we suggest that interference between viral genotypes when co-infecting the same host is key to understanding their epidemiology. We finally discuss the consequences of genotype replacement for beekeeping and for wild pollinator species. DWV vectored by Varroa destructor mites is the major cause of honey bee colony loss. DWV genotype B has largely replaced DWV genotype A in Europe. DWV genotype B is nowadays spread worldwide, expect Australia. Recombinational meltdown might explain why genotype B replaces genotype A. Replacement of DWV-A by DWV-B may exacerbate colony loss and pathogen spillover.
