Abstract

Varroa mite, Varroa destructor Anderson and Trueman (Acari: Varroidae), causes severe damage to honeybee colonies and facilitates the transmission of several bee viruses, such as deformed wing virus (DWV), which causes wing deformity in newly molted bees. In Japan, western honeybees Apis mellifera Linnaeus (Hymenoptera: Apidae) are reared for both honey production and pollination and are infested with Varroa mites. Detailed surveillance of bee viruses in both A. melliferra and V. destructor has not been conducted in Japan. We surveyed eight major bee viruses in A. mellifera and Varroa mites from Japanese apiaries. DWV is the predominant virus in both A. mellifera and V. destructor in Japan. Two strains of the virus, DWV-A and DWV-B, are considered virulent in honeybees, but only DWV-A was detected in this study. The DWV levels in honeybees were strongly correlated with the Varroa infestation rate. We also detected other viruses in both the bees and mites, such as black queen cell and Lake Sinai viruses, but at much lower infection rates than DWV. Infection rates of these viruses were higher in colonies that did not contain Varroa mites than in Varroa-infested bee colonies. Therefore, Varroa mites in Japanese apiaries could be associated with DWV transmission, but they may rarely be associated with the transmission of other viruses.

检测日本的蜜蜂病毒（膜翅目：猿科）和破坏者瓦罗虫（蛔虫科：蛀虫属

瓦氏螨--瓦氏破坏螨（Varroa destructor Anderson and Trueman）（Acari: Varroidae）会对蜜蜂蜂群造成严重破坏，并助长多种蜜蜂病毒的传播，如畸形翅病毒（DWV），它会导致刚蜕皮的蜜蜂翅膀畸形。在日本，饲养西方蜜蜂林尼厄斯蜂（膜翅目：Apidae）既是为了生产蜂蜜，也是为了授粉，并受到瓦氏螨的侵扰。日本尚未对蜜蜂病毒（A. melliferra 和 V. destructor）进行详细监测。我们调查了日本养蜂场中 A. mellifera 和 Varroa 螨虫的八种主要蜜蜂病毒。在日本，DWV 是蜜蜂和破坏螨中的主要病毒。该病毒有两种毒株，即 DWV-A 和 DWV-B，被认为对蜜蜂具有毒性，但本研究只检测到 DWV-A。蜜蜂体内的 DWV 水平与 Varroa 侵染率密切相关。我们还在蜜蜂和螨虫体内检测到其他病毒，如黑蜂王细胞病毒和西奈湖病毒，但感染率远低于 DWV。在不含瓦氏螨的蜂群中，这些病毒的感染率要高于受瓦氏螨感染的蜂群。因此，日本养蜂场中的瓦氏螨可能与 DWV 的传播有关，但它们可能很少与其他病毒的传播有关。
