蜜蜂（Apis mellifera L.）由于蜂群衰竭失调症（CCD）发病率的增加，种群数量急剧下降。蜜蜂是一种独特的关键物种，因为它的授粉活动不仅是许多野生开花植物物种生存所必需的，而且也是许多人类农业实践所必需的。CCD的日益流行对所有依赖高效授粉的大型单一作物的社会的经济和营养安全构成威胁。尽管有充分的证据表明瓦螨、农药、疾病和气候变化对CCD有贡献，但只有少数研究调查了多种因素的协同作用对CCD和CCD样症状发展的贡献。然而，科学界越来越多地认识到，不同因素的协同作用会影响蜜蜂群体的健康和行为。在这里，我们提供的证据表明，亚致死水平的吡虫啉类烟碱杀虫剂降低学习和记忆能力。当瓦螨与吡虫啉一起暴露于单个蜜蜂时，协同效应变得明显，每次试验的平均死亡率和损耗增加了一倍以上。
Honey bee (Apis mellifera L.) populations have undergone a dramatic decline as an outcome of an increasing incidence of colony collapse disorder (CCD). The honey bee is a unique keystone species because its pollination activities are not only necessary for the viability of many flowering plant species in the wild, but are also necessary for many human agricultural practices. The increasing prevalence of CCD is a threat to the economic and nutritional security of all societies that rely on efficient pollination for large monoculture crops. Although there is ample evidence that Varroa mites, pesticides, disease, and climate change contribute to CCD, only a few studies have investigated the contribution of synergism across multiple factors to the development of CCD and CCD-like symptoms. However, there is increasing acknowledgement in the scientific community that synergism across different factors affects honey bee colony health and behavior. Here, we provide evidence that sub-lethal levels of imidacloprid neonicotinoid pesticide reduce learning and memory capabilities. Synergistic effects become apparent when Varroa mites together with imidacloprid exposure to individual bees more than doubled average mortality and attrition per trial.
