Varroa destructor is an ectoparasitic mite that affects colonies of honey bee Apis mellifera worldwide. In the last years, substances of botanical origin have emerged as natural alternative acaricides to diminish the population levels of the mite. In the present work, the bioactivity of propolis from different geographical locations of Pampean region from Argentina on V. destructor was evaluated. Fourteen propolis samples were organoleptic and physicochemically characterized and, by means topical applications, their activity was tested on mites. All propolis had a homogeneous composition and the bioactivity levels against mites were comparable among the different propolis samples. The percentage of mites killed by the treatments ranged between 60.5% and 90% after 30 s of exposure. Thus, V. destructor was highly susceptible to propolis. Moreover, the mites remained anesthetized during the first hours after topical treatment. The results suggest that propolis from Argentinean pampas could be incorporated in honey bee colonies as acaricidal treatment by spraying.
瓦螨是一种外寄生虫螨,影响全球的蜜蜂 Apis mellifera 种群。在过去的几年中,植物源物质已成为天然替代杀螨剂,以降低螨的种群水平。在本工作中,评估了来自阿根廷潘帕斯地区不同地理位置的蜂胶对瓦螨的生物活性。对 14 个蜂胶样品进行了感官和物理化学特性分析,并通过局部应用测试了它们对螨虫的活性。所有蜂胶的成分均均匀,对螨虫的生物活性水平在不同的蜂胶样品之间相当。处理后 30 秒内,杀死的螨虫百分比在 60.5%至 90%之间。因此,瓦螨对蜂胶高度敏感。此外,在局部处理后的头几个小时内,螨虫仍然处于麻醉状态。结果表明,来自阿根廷潘帕斯草原的蜂胶可以通过喷洒的方式作为杀螨剂添加到蜜蜂群体中。
