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

ABSTRACT

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. (AU)
