Deformed wing virus (DWV) in western honey bees (Apis mellifera) often remains asymptomatic in workers and drones, and symptoms have never been described from queens. However, intense infections linked to parasitism by the mite Varroa destructor can cause worker wing deformity and death within 67 h of emergence. Ten workers (eight with deformed wings and two with normal wings) and three drones (two with deformed wings and one with normal wings) from two colonies infected with V. destructor from Nova Scotia, Canada, and two newly-emerged queens (one with deformed wings and one with normal wings) from two colonies infected with V. destructor from Prince Edward Island, Canada, were genetically analyzed for DWV. We detected DWV in all workers and drones, regardless of wing morphology, but only in the deformed-winged queen. This is the first report of DWV from Atlantic Canada and the first detection of a symptomatic queen with DWV from anywhere.
西方蜜蜂（意大利蜜蜂）中的残翅病毒（DWV）在工蜂和雄蜂中通常无症状，且从未有过蜂王出现症状的描述。然而，与狄斯瓦螨寄生相关的严重感染可导致工蜂在羽化后67小时内翅膀畸形并死亡。对来自加拿大新斯科舍省两个感染狄斯瓦螨的蜂群中的10只工蜂（8只翅膀畸形，2只翅膀正常）、3只雄蜂（2只翅膀畸形，1只翅膀正常）以及来自加拿大爱德华王子岛两个感染狄斯瓦螨的蜂群中的2只新羽化蜂王（1只翅膀畸形，1只翅膀正常）进行了残翅病毒的基因分析。我们在所有工蜂和雄蜂中均检测到了残翅病毒，无论其翅膀形态如何，但仅在翅膀畸形的蜂王中检测到。这是加拿大大西洋地区关于残翅病毒的首次报告，也是在任何地方首次检测到有症状的感染残翅病毒的蜂王。
