The aim of presented study was to determine the effect of changing honey flow and variable weather conditions on the flight activity of honey-bee foragers. The study was carried out on 12 bees colonies, transported onto different honey flows. Bees foragers returning from the field were counted on the flight-board, during 15 minutes, 3 times per day: at 9.00–10.00, 12.00–13.00 and 17.00–18.00, once a week, from 24 April to 15 August 2004. The obtained data were converted into 1 hour. The study showed considerable influence of a sort of present use and the flowering stage of fly round plants onto volatile activity of bee foragers – bees were most active in the peak period of flowering of richly occurring uses. Weather conditions formed here an important complex of factors – optimal were temperatures between 16–26^oC and a lack or just weak wind were optimal. On the other hand the degree of cloudiness was of less importance in this respect. The swarming behavior in the colonies and the swarming bees generated decrease in the flight activity of honey-bees foragers.
