Conteúdo: 	The hygienic behavior of the honeybees is a natural mechanism of resistance to diseases and parasites, characterised by uncapping and remove dead, sick or damaged brood from the alveoli. The selection of Africanized honeybees for this feature reduces the reproduction rate of Varroa destructor mite and, consequently, the infestation rate on adult worker honeybees. The aim of this study was to evaluate the hygienic behavior and variables related to the varroa mite in Apis mellifera colonies with queens from different origins from October 2013 to June 2014. It was evaluated queens from the selection program at Universidade Estadual de Maringá (Maringá, state of Paraná, Brazil), and from a queen breeder of Santa Terezinha, state of Santa Catarina, and non-selected queens randomly chosen in the experimental apiary of Irineópolis, state of Santa Catarina. The colonies from Maringa presented higher invasion rate of Varroa in pupae alveoli and total reproduction of varroa than queens from Santa Terezinha, and unselected queens and a reduction of hygienic behavior ? 84%. This group presented reduction of effective reproduction of Varroa, averaging 2.3 fertile offspring. The colonies with queens from Santa Terezinha, although less pronounced, presented higher invasion rate of Varroa in pupae alveoli from the reduction of hygienic behavior, which remained stable, averaging 92.0%. For this group the total reproduction of Varroa was 1.7 and the effective reproduction was 0.9. The colonies from Irineópolis had the lowest hygienic behavior (78.0%) and the highest total reproduction (12.6) and effective reproduction of Varroa (5.3). The use of selected queens in wild and normal colonies reduced the varroa population dynamics and reduced invasion rates of Varroa in pupae alveoli and total and effective mite reproduction.
