The ectoparasitic mite Varroa destructor Anderson and Trueman (Acari: Varroidae) is a pest that severely damages honey bee health worldwide. This mite is considered a major reason for winter colony loss of the western honey bee Apis mellifera Linnaeus (Hymenoptera: Apidae). Monitoring of Varroa mites in honey bee colonies is required for effective management of Varroa infestations. The mite is dislodged from adult bees when the bees roll in powdered sugar. The sugar roll test is one of the major methods used to survey V. destructor infestations in honeybee colonies. However, powdered sugar agglomerates during commodity distribution to the customers or under humid conditions. In this study, roasted soybean flour was evaluated as a powder for Varroa mite detection, because this powder rarely forms a hard agglomerate. Roasted soybean flour may eliminate Varroa mites from adult bees as well as powdered sugar. Therefore, the roasted soybean flour can be a useful powder for convenient Varroa monitoring under humid conditions.

一种使用烤大豆粉检测瓦螨（Acari：Varroidae）的简便方法

外寄生螨 Varroa destructor Anderson and Trueman (Acari: Varroidae) 是一种严重损害全球蜜蜂健康的害虫。这种螨被认为是西部蜜蜂Apis mellifera Linnaeus（膜翅目：蜂科）冬季群体丧失的主要原因。需要对蜜蜂群中的瓦螨进行监测，以有效管理瓦螨侵扰。当蜜蜂在糖粉中滚动时，螨虫就会从成年蜜蜂身上脱落。糖卷试验是用于调查蜜蜂群落中 V. destructor 感染的主要方法之一。然而，糖粉在向客户配送商品过程中或在潮湿条件下会结块。在这项研究中，烤豆粉被评估为用于瓦螨检测的粉末，因为这种粉末很少形成坚硬的团块。烤大豆粉可以消除成年蜜蜂的瓦螨以及糖粉。因此，烤大豆粉可作为一种有用的粉末，可在潮湿条件下方便地监测瓦螨。
