Humulus lupulus, commonly known as hops has widely been used in breweries globally, however, the acaricidal properties of H. lupulus derived products could also be a novel and interesting avenue of study against insect pests. We tested the antiparasitic activity of H. lupulus essential oils against the honeybee mite Varroa destructor, and its bioactivity against the honeybee Apis mellifera. The hop varieties used in this study were Cascade, Victoria, Spalt, and Mapuche. The essential oils were extracted from flowers by hydrodistillation and then characterized by CG-MS. We evaluated the toxicity of hop essential oils against mites, adult bees (A. mellifera) and larvae, and whether the oils were an attractant or repellent to mites. The major components of the oils for all varieties were β-myrcene, myrcene, beta-farnesene, alpha, and beta cariophylene. Bioassays revealed that essential oils from all the varieties were toxic to the V. destructor mite. Victoria essential oil was the most toxic to V. destructor. The oils did not act as a repellent or attractant to the mites, and the bee (A. mellifera) mortality associated with complete exposure to the essential oil application was moderate to low. The results presented here provide promising results for the application of essential oils from hops grown in South America as an alternative method for controlling the honeybee mite Varroa destructor.

草，通常称为酒花，已在全球啤酒厂中广泛使用，但是however草产品的杀螨特性也可能是研究害虫的新颖而有趣的途径。我们测试了山。香精油对蜜蜂螨Varroa破坏物的抗寄生虫活性，以及其对蜜蜂蜜蜂的生物活性。本研究中使用的啤酒花品种是Cascade，Victoria，Spalt和Mapuche。通过加水蒸馏从花中提取香精油，然后通过CG-MS进行表征。我们评估了蛇麻草精油对螨虫，成年蜜蜂（A. mellifera）和幼虫，以及这些油是螨的引诱剂还是驱虫剂。所有品种的油的主要成分是β-月桂烯，月桂烯，β-法呢烯，α和β-亚丙基。生物测定法显示，所有品种的精油对杀螨虫均具有毒性。维多利亚精油是最有毒的五析构函数。这些油不能作为螨的驱避剂或引诱剂，完全暴露于精油中所引起的蜜蜂（A. mellifera）死亡率中等至较低。此处介绍的结果为应用南美南美蛇麻草精油作为控制蜜蜂螨Varroa破坏剂的替代方法提供了有希望的结果。
