Abstract

The aim of this article was to investigate the effect of the use of queen excluder at the hive entrance on Apis mellifera hoarding activity, pollen load and hive development in six hives, three of which provided with queen excluders. An average of 51.4%, 37.0% and 11.6% of the Apis mellifera workers which entered the hives from 8 to 11 a.m., 11 to 2 p.m. and 2 to 5 p.m., respectively, were pollen-loaded. Only 0.0175% of them lost their pollen load when passing the queen excluder, which amounted to 0.06% of total pollen collected/day/hive. The queen excluder caused the reduction of 15.2% to the entrance of pollen-loaded bees and 19.4% to the entrance of non-pollen-loaded bees. On average, the weight of the pollen load represented 13.88% ± 8.4% of the bee body weight. The results also indicated that the hoarding activity was reduced by the queen excluder.
