Beekeepers all across the world are suffering important losses of their colonies, and the parasitic mites Varroa destructor and Nosema sp, as well as several bee viruses, are being pointed out as the possible causes of these losses, generally associated with environmental and management factors. The objective of the present study was to evaluate 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-, Kashmir bee virus ?KBV-, Israeli acute bee paralysis virus ?IAPV-, and Sacbrood bee virus ?SBV), as well as the prevalence of Nosema sp. and Varroa destructor, and their possible associated factors, under temperate and subtropical climate conditions in Argentinean colonies. A total of 385 colonies distributed in five Argentinean eco-regions were examined after honey harvest. The final multivariable model revealed only one variable associated with the presence of DWV and two with the presence of ABPV. The apiary random effect was significant in both cases (P = 0.018; P = 0.006, respectively). Colonies with a Varroa infestation rate >3% showed higher presence of DWV than colonies with
