Abstract

Viruses occupy a large proportion of the pathogen communities within honey bee colonies, with more than 80 species detected in Apis mellifera. Honey bee viruses are globally distributed and several species have been linked to honey bee diseases that threaten colony health. However, less is known about the ecology and epidemiology of viruses within honey bee colonies, and in particular whether a link exists between virus temporal dynamics and seasonal variations and/or colony dynamics. Using a large-scale longitudinal survey conducted over three years, we report the prevalence and abundance of deformed wing virus, acute bee paralysis virus, black queen cell virus, chronic bee paralysis virus and sacbrood virus (DWV, ABPV complex, BQCV, CBPV and SBV) in more than 300 colonies located in two different environments of southern Europe (Provence in France, Piemonte in Italy), and exhibiting contrasted climatic conditions. Monthly measurements performed throughout the beekeeping seasons indicate distinct seasonal trends in prevalence and abundance of the five virus species: DWV, SBV and ABPV complex displayed marked seasonal variations, that were similar in both environments tested. We also highlight the link between seasonal virus dynamics and colony dynamics for SBV/BQCV, and parasite dynamics for DWV. This study improves our understanding of virus ecology within honey bee colonies.

三年纵向调查中五种主要蜜蜂病毒的季节性变化

在蜜蜂群落中，病毒占据了很大比例的病原体群落，在蜜蜂中检测到80多种病毒。蜜蜂病毒在全球分布，一些物种与威胁蜂群健康的蜜蜂疾病有关。然而，人们对蜂群内病毒的生态学和流行病学知之甚少，特别是病毒的时间动态与季节变化和/或蜂群动态之间是否存在联系。通过一项为期三年的大规模纵向调查，我们报告了在欧洲南部两个不同环境（法国普罗旺斯和意大利皮埃蒙特）的300多个蜂群中，变形翼病毒、急性蜂麻痹病毒、黑蜂后细胞病毒、慢性蜂麻痹病毒和囊化病毒（DWV、ABPV复合物、BQCV、CBPV和SBV）的流行度和丰度，并展示了不同的气候条件。在整个养蜂季节进行的月度测量表明，五种病毒的流行度和丰度有明显的季节性趋势：DWV、SBV和ABPV复合物显示出明显的季节性变化，这在两个测试环境中是相似的。我们还强调了SBV/BQCV的季节性病毒动力学和群体动力学之间的联系，以及DWV的寄生虫动力学。本研究提高了我们对蜂群内病毒生态学的认识。

期刊介绍： Apidologie is a peer-reviewed journal devoted to the biology of insects belonging to the superfamily Apoidea. Its range of coverage includes behavior, ecology, pollination, genetics, physiology, systematics, toxicology and pathology. Also accepted are papers on the rearing, exploitation and practical use of Apoidea and their products, as far as they make a clear contribution to the understanding of bee biology. Apidologie is an official publication of the Institut National de la Recherche Agronomique (INRA) and Deutscher Imkerbund E.V. (D.I.B.)
