摘要

寄生螨 Varroa destructor(安德森和特鲁曼)是蜜蜂蜂群的最大威胁之一。当秋季瓦氏螨虫害达到破坏性程度时,必须进行快速控制,以尽量减少对蜂群的损害。我们在美国东南部进行了一项田间试验,以确定注册处理剂(Apivar,阿米曲兹;Apiguard,百里酚)的组合是否能快速有效地控制瓦鲁虫。我们将接受了这种组合处理的蜂群与接受了以双甲脒为基础的阳性对照处理的蜂群进行了比较:(i) 单独使用 Apivar;或 (ii) 双甲脒乳油("双甲脒 EC")。阿米曲拉 EC 虽然没有注册,但在美国被养蜂人使用,部分原因是它被认为能比注册产品更快速、更有效地控制 Varroa。根据治疗 21 天后对蜂群中 Varroa 侵染率的测量,我们发现组合疗法控制 Varroa 的速度几乎与 amitraz EC 疗法相同:这种疗法或其他组合疗法可用于管理 Varroa。在为期 42 天的试验结束时,阿米曲拉 EC 组蜂群的蜜蜂数量高于 Apivar 组,这表明快速控制有助于减少 Varroa 的危害。组合组蜂群的蜜蜂数量低于阿米曲拉 EC 组,这表明需要优化组合处理以避免对蜂群造成损害。

Combined treatment with amitraz and thymol to manage Varroa destructor mites (Acari: Varroidae) in Apis mellifera honey bee colonies (Hymenoptera: Apidae).

The parasitic mite Varroa destructor (Anderson and Trueman) is one of the greatest stressors of Apis mellifera (L.) honey bee colonies. When Varroa infestations reach damaging levels during fall, rapid control is necessary to minimize damage to colonies. We performed a field trial in the US Southeast to determine if a combination of registered treatments (Apivar, amitraz-based; and Apiguard, thymol-based) could provide rapid and effective control of Varroa. We compared colonies that received this combination treatment against colonies that received amitraz-based positive control treatments: (i) Apivar alone; or (ii) amitraz emulsifiable concentrate ("amitraz EC"). While not registered, amitraz EC is used by beekeepers in the United States in part because it is thought to control Varroa more rapidly and effectively than registered products. Based on measurements of Varroa infestation rates of colonies after 21 days of treatment, we found that the combination treatment controlled Varroa nearly as rapidly as the amitraz EC treatment: this or other combinations could be useful for Varroa management. At the end of the 42-day trial, colonies in the amitraz EC group had higher bee populations than those in the Apivar group, which suggests that rapid control helps reduce Varroa damage. Colonies in the combination group had lower bee populations than those in the amitraz EC group, which indicates that the combination treatment needs to be optimized to avoid damage to colonies.

期刊介绍: The Journal of Insect Science was founded with support from the University of Arizona library in 2001 by Dr. Henry Hagedorn, who served as editor-in-chief until his death in January 2014. The Entomological Society of America was very pleased to add the Journal of Insect Science to its publishing portfolio in 2014. The fully open access journal publishes papers in all aspects of the biology of insects and other arthropods from the molecular to the ecological, and their agricultural and medical impact.
