In Argentina, bee virus studies are still incipient, and there are no studies regarding the climatic effect. The aim of this study was to assess and compare the presence of honeybee viruses in different climatic regions from Argentina. A total of 385 colonies distributed in five Argentinean eco-regions were examined to evaluate the percentage of infestation with Varroa destructor and the presence of seven virus species (Deformed wing virus, DWV; Acute bee paralysis virus, ABPV; Chronic bee paralysis virus, CBPV; Black queen cell virus, BQCV; Kashmer bee virus, KBV; Israeli acute bee paralysis virus, IAPV; and Sacbrood bee virus, SBV) after honey yield. Two viruses, KBV and IAPV, were not detected. The other five viruses were found in different prevalences: DWV (35%), ABPV (21.5%), BQCV (8.0%), CBPV (2.2%), and SBV (1.1%). We found double and triple viral associations in approximately 25% of the sampled colonies. The mean V. destructor infestation in the colonies prior to the acaricide treatment was 7.12%±8.7%. The knowledge of the prevalence of these viruses in the region and their relation with the mite and other possible influencing factors is important for preventing colony losses. Further studies are necessary to identify the risk factors associated with virus presence and its relationship with other pathogens such as V. destructor.
在阿根廷，蜜蜂病毒研究仍处于起步阶段，且尚无关于气候影响的研究。本研究的目的是评估和比较阿根廷不同气候区域中蜜蜂病毒的存在情况。对分布在阿根廷五个生态区域的385个蜂群进行了检查，以评估狄斯瓦螨的侵染百分比以及在蜂蜜收获后七种病毒（残翅病毒，DWV；急性蜜蜂麻痹病毒，ABPV；慢性蜜蜂麻痹病毒，CBPV；黑蜂王台病毒，BQCV；克什米尔蜜蜂病毒，KBV；以色列急性蜜蜂麻痹病毒，IAPV；以及囊状幼虫病病毒，SBV）的存在情况。未检测到两种病毒，即KBV和IAPV。发现其他五种病毒的流行率各不相同：DWV（35%）、ABPV（21.5%）、BQCV（8.0%）、CBPV（2.2%）和SBV（1.1%）。在大约25%的采样蜂群中发现了双重和三重病毒关联。在进行杀螨剂处理之前，蜂群中狄斯瓦螨的平均侵染率为7.12%±8.7%。了解这些病毒在该地区的流行情况及其与螨虫和其他可能影响因素的关系对于预防蜂群损失很重要。有必要进一步开展研究，以确定与病毒存在相关的风险因素及其与其他病原体（如狄斯瓦螨）的关系。
