Influence of Fulvic Acid on the Increase in Lifespan and the Physiological State of Bees

The results of research for the years 2020–2021 are presented. The results of the influence of different doses of fulvic acid on the increase in the lifespan of bees kept in entomological cages and improvement of their physiological state are given. The studies were carried out under laboratory conditions at an air temperature of +27 ± 2°C, on bees of the spring–summer generation. The experiment included three groups of bees in triplicate. The first group was the control; in this group, the bees consumed a 60% sucrose solution as supplementary feeding. In the second group, the bees consumed a 60% sucrose solution, to which fulvic acid was added, at a dose of 0.1 mL per 200 m/L of solution. The third group was fed with a 60% sucrose solution, to which fulvic acid was added, at a dose of 0.2 m/L per 200 m/L of solution. According to the results of this research, it was found that fulvic acid at a dose of 0.1 mL per 200 m/L of solution contributed to the prolongation of the lifespan of bees. In this variant of the experiment, 30–40% of the deaths of bees occurred five days later than in the control group, and 50% and 60% of deaths, four days later than in the control group. Fulvic acid, when an increased dose was used, did not have a reliable 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.
