The effect of the method of preservation of bee honey on the development of the pharyngeal gland in honey bees Apis mellifera L

Modern agricultural systems involve the use of large monocultures, which significantly limits variety flowers for bees. The article presents data on biochemical composition monofloral bee pollen and its influence development pharyngeal glands in honey conducted studies give reason to believe that protein content depends species origin preservation method. studied samples show amount ranges from 11.9 24.9 %. maximum was found fresh rapeseed apple pollen. To study diets growth gland, 9 groups analogous families were formed, 3 each, fed three types feed. first type is following plants: tree, dandelion, winter rapeseed, buckwheat, clover, chestnut, raspberry. second a similar pollen, only after year deep freezing storage. ration third consisted indicated process harvesting it dried. Along with this, formed group divided into two more subgroups. Some consumed mixed feed equal proportions, others did not have any duration experiment 15 days. On 10th day, acini gland determined. morphometry dynamics vesicle filling indicate best indicators bees A highly beneficial increase length width revealed by 36.4 34.7 % compared consume at all. received seed their diet fully demonstrated potential royal jelly production. worst dried dandelion nectar. In this bees, area ranged 15.5 16.4 thousand μm2. relationship between degree revealed. Of researched methods preservation, conditions turned out be best. experimental has negative effect internal body Key words: Apis mellifera L., nutrition, protein,
