Taxa de infestação por ácaro Varroa destructor em apiários sob georreferenciamento / Rate of infestation by Varroa destructor in apiaries under geoprocessing

The rate of infestation of Varroa destructor was investigated in 128 swarms of bees, distributed in three distinct apiaries: with (two) and without (one) superposition of the visualized feeding areas, identified by geoprocessing analysis. A higher infestation rate was observed where superposition in the feeding areas was observed (averages 11.0% and 9.3%) in contrast with the swarms in the apiary where there were no common feeding areas (3.3%). This suggests that superposition of visualized feeding areas is associated with the varroatosis occurrence and that it favors the enhancement of the mite infestation rate in the beehives.
