意大利蜜蜂的群体间距离显着影响寄生螨瓦螨的群体数量。我们建立了 15 个养蜂场，每个养蜂场包含两个蜂群。每对养蜂场的蜂群间距离分别为 0、10 或 100 米。使菌落几乎没有螨虫，然后将每对中的一个菌落接种 300 只雌性螨虫（螨供体菌落），而另一个则保持未接种（螨虫受体菌落）。经过 4 个月的监测，全模型分析表明，蜂群间隔 100 m 的养蜂场的平均螨数低于 0 或 10 m 养蜂场。菌落类型、距离和采样日期之间存在交互作用；然而，当存在显着差异时，100 m 养蜂场的螨虫数量总是低于 10 m 养蜂场。这些发现提出了瓦螨种群在景观尺度上受到资源调节的可能性：邻近的群体以额外的蜂巢形式构成了螨虫的繁殖资源。
Inter-colony distance of Apis mellifera significantly affects colony numbers of the parasitic mite Varroa destructor. We set up 15 apiaries, each consisting of two colonies. Each apiary pair was assigned an inter-colony distance of 0, 10, or 100 m. Colonies were rendered nearly mite-free, then one colony in each pair was seeded with 300 female mites (mite-donor colony), while the other remained uninoculated (mite-recipient colony). After 4 months of monitoring, a whole-model analysis showed that apiaries in which colonies were spaced 100 m apart contained lower average mite numbers than 0 or 10 m apiaries. There were interactions among colony type, distance, and sampling date; however, when there were significant differences, mite numbers were always lower in 100 m apiaries than 10 m apiaries. These findings pose the possibility that Varroa populations are resource regulated at a landscape scale: near-neighbor colonies constitute reproductive resource for mites in the form of additional bee brood.
