During 2015 was evaluated the sanitary condition of six apiaries from areas with predominance of forest localized in Formosa Province. Samples of bees from six colonies of each apiary were taken in three moment of the year, to determine the abundance of Nosema spores and species of Nosema, percentage of infestation with Varroa and viruses presence, the apiaries did not receive acaricide treatment. Poblational parameters were evaluated (CCA, CCC, CCP, CCM). Post-honey harvest period showed the highest Varroa infestation (5,15 ± 4,69%) and evidenced a significant reduction at the beginning of the beginning of honey season period (3,24 ± 2,45%). The spores of Nosema counts showed a progressive increase during the study. N. ceranae was found in 22 % of the apiaries, in the rest was found N. apis. During the post-honey harvest period 57,9%, 28,9% and 7,9% of the colonies were positive to deformed wing virus, acute paralysis virus and black queen virus, respectively.
