狄斯瓦螨是一种外寄生螨，在全球范围内造成蜂群的重大损失。螨携带一系列致病病毒，其中最重要的是畸形翅病毒（DWV）。在没有瓦螨属的情况下，DWV作为低水平、高度多样化的病毒群体存在。然而，当通过瓦螨属传播时，某些变体变得高度升高，并且可能变得接近克隆并引起症状性感染。当被寄生的工蜂从邻近的蜂箱漂流或抢劫时，会发生蜂群之间的螨传播。这些活动可能导致螨水平升高，但DWV种群的变化，冬季群体损失的主要决定因素，尚未确定。在互惠研究中，我们调查了螨的去除或其收购对DWV人口的影响。当螨从严重感染的菌落中去除时，病毒载量显著而迅速地减少。相反，将瓦螨属初治菌落置于螨侵染的蜂箱中导致螨的获得和病毒种群的伴随变化。无论滴度如何，我们都观察到了近克隆和高度分化的病毒群体，这表明变化是随机的和菌落特异性的。我们的研究结果对全面或局部实施瓦螨属控制计划的地区的战略结果具有影响。
Varroa destructor is an ectoparasitic mite associated with significant losses of honeybee colonies globally. The mite vectors a range of pathogenic viruses, the most important of which is the Deformed wing virus (DWV). In the absence of Varroa, DWV exists as a low-level, highly diverse virus population. However, when transmitted by Varroa, certain variants become highly elevated, and may become near-clonal and cause symptomatic infections. Mite transmission between colonies can occur when parasitised workers drift from or rob adjacent hives. These activities can result in elevated mite levels, but the resulting change in the DWV population, the primary determinant of winter colony losses, has not been determined. In reciprocal studies, we investigated the influence of the removal of mites, or their acquisition, on the DWV population. When mites were removed from heavily infested colonies, there was a striking and rapid reduction in virus load. Conversely, siting Varroa-naïve colonies in a mite-infested apiary resulted in the acquisition of mites and concomitant changes in the virus population. We observed both near-clonal and highly divergent virus populations regardless of titre, suggesting changes were stochastic and colony-specific. Our findings have implications for the outcome of strategies in areas with total or patchy implementation of Varroa control plans.
