INFLUENCE OF VETOSPORIN-G ON THE BEE COLONS DEVELOPMENT IN THE CONDITIONS OF THE TYUMEN REGION

Abstract

The effect of the probiotics Vetosporin-Zh, PcheloNormoSil and ApiVrach on the lifespan of bees was studied in laboratory conditions.For this purpose, 26 cages containing 50 three-day-old bees were selected, which were divided into 4 groups (3 experimental groups of 7 cages each and a control group of 5 cages).In the experiment, bees were fed sugar syrup containing drugs in accordance with the instructions for their use. In the control bees were given sugar syrup. The studies were carried out in accordance with “Methodological  recommendations for studying the toxic effects of pesticides and biological products on bees”. It was established that of the tested drugs, only Vetosporin-Zh significantly increased the lifesspan  of experimental bees compared to the control by 1.4 times. To conduct research in the apiary, 14 bee colonies were selected and divided into 2 equal groups - experimental and control. Experimental colonies were fed 1 liter of sugar syrup containing 1 ml of Vetosporin-Zh three times with an interval of 3 days. Control colonies received syrup without the drug. Inspection of bee colonies was carried out every 12 days, and the number of frames, printed brood and honey in each family was taken into account. Determined that feeding experimental bee colonies with sugar syrup containing Vetosporin Zh - contributed to an increase in their strength by 1.3 times, printed brood and honey by 1.3 - 1.4 times compared to control families.
