Sažetak
The incorrect or excessive use of antibiotics and of acaricides against bee diseases, as well as various stressors, including queen rearing, can increase the incidence of chalk-brood. A promising drug against this disease could be Enilconazol. Its influence on bees, bee brood and queens was therefore tested for the first time under laboratory and apiary conditions. Amounts of 200, 400, and 1000 mg of Enilconazol were dissolved in 96% ethyl alcohol, added to 50 ml of sugar solution (1:1, w/v) and fed to experimental groups. Bees accepted the experimental feeds well. Observation of bees and bee brood during 30 days in the laboratory glass hives with one frame (apisarium) showed no difference between treated and control groups fed with plain sugar solution. The influence of Enilconazol on quality of queens was examined in AZ type pavilion hives with several especially prepared and divided frames. It was established that during 25 days there was no difference between treated and control colonies in acceptance and vitality of queens and in development of bee brood.
