The research aimed to test protein mineral supplementation on the prevalence of Leptus sp., Varroa destructor and Vairimorpha sp. in Africanized Apis mellifera colonies. The experiment was in a Completely Randomized Design, with six treatments and five replications. The treatments (except T1 – without supplementation) were made with sucrose and water (syrup): T2 – syrup; T3- commercial amino acid complex; T4- yeast residue; T5- bentonite; T6- mixes yeast residue and bentonite. The composition of yeast and bentonite residues, food consumption, colony weight, rate of Leptus sp., V. destructor and levels of Vairimorpha sp. microsporidia were analyzed. Different levels of dry matter, mineral material and crude protein were found in treatments T4 (20.31; 4.89; 43.55), T5 (7.55; 50.70; 4.86) and T6 (13.41; 42.86; 26.90). The average supplement consumption was 79.20% and only in T1 was there a significant difference in the weight of the colonies (8.70 kg = initial; 6.80 kg = final). Significant differences were observed in the rate of V. destructor in T2 and T3, as well as in the levels of infection by Vairimorpha sp. in both treatments (p ≤ 0.05). It is concluded that T2 and T3 increased the rate of V. destructor and the levels of infection by Vairimorpha sp. Treatments T4, T5 and T6 did not show significant changes in the rates of infestation by Leptus sp. and V. destructor or infection by Vairimorpha sp. T4 presented ideal protein and mineral levels for the diet of Africanized A. mellifera.
