Monitoring of Bee Colonies' Activity During the Major Gatherings in 2017.

The assessment of the meteorological factors, in direct correlation with the nectar release and honey production, helps beekeepers with the organization of the technological activities within the apiary (determination of the pastoral schedule, supplementary feedings, reproduction of bee colonies, honey harvest, etc.). The study was carried out between 14^th of April and 20^th of July 2017, on 20 Apis mellifera carpatica bee colonies, maintained in multi-layer and Dadant beehives. The bee colonies were transported in field for rape, acacia and sunflower gathering and monitored with the help of the BeeWatch Professional device. The rape and acacia gatherings were negatively influenced by low temperatures and heavy rainfall, which impeded the capitalization of the melliferous potential. The bee colonies gathered only 5 kg rape honey and 3.9 kg acacia honey/bee colony/period. As regards the sunflower, the weather conditions were optimal for gathering, and the bee colonies gathered the supplies necessary for winter and also 5 kg honey extra. The honey production obtained by the bee colonies studied was not influenced by the beehive type; it was strongly influenced by the environmental factors, temperature and humidity.
