美国和欧洲蜜蜂（Apis mellifera）群体健康状况的突然和严重下降部分归因于新出现的微生物病原体，然而，影响背后的机制尚不清楚。使用环形飞行米尔斯，我们测量了飞行距离和持续时间的积极觅食，健康的蜜蜂从标准的殖民地采样，然后量化感染水平微孢子虫cerebral和畸形翼病毒复合体（DWV）的每只蜜蜂。无论是N的存在还是N的数量。尽管感染的自然水平对飞行距离或持续时间没有任何影响，但DWV的存在使飞行距离减少了三分之二，持续时间减少了一半。DWV的数量与飞行距离和持续时间具有显著但弱的正相关性，然而，考虑到的少量变化表明需要通过剂量反应试验进行进一步研究。我们的结论是，广泛的，自然发生的DWV感染水平削弱了蜜蜂的飞行能力，高水平的群体内流行可能会降低效率，增加资源获取的成本。在预测病原体对蜂群健康和功能的影响时，应考虑对飞行性能的亚致死效应。
Sudden and severe declines in honey bee (Apis mellifera) colony health in the US and Europe have been attributed, in part, to emergent microbial pathogens, however, the mechanisms behind the impact are unclear. Using roundabout flight mills, we measured the flight distance and duration of actively foraging, healthy‐looking honey bees sampled from standard colonies, before quantifying the level of infection by Nosema ceranae and Deformed Wing Virus complex (DWV) for each bee. Neither the presence nor the quantity of N. ceranae were at low, natural levels of infection had any effect on flight distance or duration, but presence of DWV reduced flight distance by two thirds and duration by one half. Quantity of DWV was shown to have a significant, but weakly positive relation with flight distance and duration, however, the low amount of variation that was accounted for suggests further investigation by dose‐response assays is required. We conclude that widespread, naturally occurring levels of infection by DWV weaken the flight ability of honey bees and high levels of within‐colony prevalence are likely to reduce efficiency and increase the cost of resource acquisition. Predictions of implications of pathogens on colony health and function should take account of sublethal effects on flight performance.
