破坏蜂是一种寄生于未成熟和成年蜜蜂的外寄生螨，可以将几种单链RNA病毒传播给宿主。瓦螨在育雏细胞中繁殖，螨种群在春季和夏季产卵时增加。螨虫的数量也会急剧上升，特别是在秋天，因为瓦螨会迁徙到觅食者的蜂巢中。varroa和病毒含量高的蜂群通常在冬天死亡。由于花粉对免疫和菌落生长有积极作用，因此饲喂花粉可以降低病毒水平，提高存活率。我们比较了添加（喂食）和不添加（未喂食）花粉的蜂群的varroa和病毒水平和越冬存活率。我们还测量了在种群入口捕获带螨觅食者（FWM）的频率，以确定其与varroa和病毒水平的关系。饲喂花粉的菌落比未饲喂花粉的菌落大，存活时间长。Varroa种群数量和变形翼病毒（DWV）水平在整个季节上升，并且在喂食和未喂食的种群之间相似。在饲喂和未饲喂的种群中，varroa种群的生长与FWM相关，并显著影响DWV水平。饲喂频率的增加和对蚁群的影响可能会降低添加花粉对蚁群免疫功能的积极影响。然而，采食花粉可以刺激菌落生长，从而提高菌落存活率。本文的在线版本（10.1007/s10493-020-00562-7）包含补充材料，仅供授权用户使用。
Varroa destructor is an ectoparasitic mite of immature and adult honey bees that can transmit several single-stranded RNA viruses to its host. Varroa reproduce in brood cells, and mite populations increase as colonies produce brood in spring and summer. Mite numbers also can sharply rise, particularly in the fall, by the migration of varroa into hives on foragers. Colonies with high levels of varroa and viruses often die over the winter. Feeding colonies pollen might keep virus levels low and improve survival because of the positive effects of pollen on immunity and colony growth. We compared varroa and virus levels and overwinter survival in colonies with (fed) and without (unfed) supplemental pollen. We also measured the frequency of capturing foragers with mites (FWM) at colony entrances to determine its relationship to varroa and virus levels. Colonies fed supplemental pollen were larger than unfed colonies and survived longer. Varroa populations and levels of Deformed wing virus (DWV) rose throughout the season, and were similar between fed and unfed colonies. The growth of varroa populations was correlated with FWM in fed and unfed colonies, and significantly affected DWV levels. Increasing frequencies of FWM and the effects on varroa populations might reduce the positive influence of supplemental pollen on immune function. However, pollen feeding can stimulate colony growth and this can improve colony survival.
