INFLUENCE OF FULVIC ACID ON INCREASING LIFE AND PHYSIOLOGICAL STATE OF BEEES

The article presents the results of research for (2020–2021). The results of the influence of different doses of fulvic acid on increasing the life span of bees kept in entomological cages and improving their physiological state are given. The studies were carried out in laboratory conditions at an air temperature of +27 ± 2°C, on bees of spring-summer generation. The experiment included three groups of bees in triplicate. The first group – control, in this group, the bees consumed 60% sucrose solution as top dressing. In the second group, the bees consumed a 60% sucrose solution, to which fulvic acid was added, at the rate of 0.1 ml per 200 ml of solution. The third group was fed a 60% sucrose solution, to which fulvic acid was added, at the rate of 0.2 ml per 200 ml of solution. According to the results of the research, it was found that fulvic acid at a dose of 0.1 ml per 200 ml of solution contributed to the prolongation of the life of bees. In this variant of the experiment, 30–40% death of bees occurred five, and 50% and 60% four days later than in the control. Fulvic acid, where an increased dose was used, did not have a significant effect on the lifespan of bees. As the bees aged, fulvic acid in both variants of the experiment reduced the load on the rectum and toxicity to the body, thereby improving their physiological state.
