Royal jelly is a secretion of the hypopharyngeal and mandibular glands of young nurse bees, used to feed larvae in the first three days throughout the larval period. The research evaluated the impact of the biostimulator “Chloramicob” on royal jelly production. It was established that the optimal dose is 2.25 ml/L administered to nurse bees (1 L sugar syrup/day for three days). In the first stage, it increased the larval acceptance rate by 12.5-27.5%, the mass of the brood by 2.4-14.4% and the total royal jelly production by 25.45-40.04%. In the second stage, increases of 10.0-24.3% in the number of larvae raised, 1.49-1.79% in the diameter of the queen cells and 41.14-93.38% in total royal jelly production. In the third stage, there were increases of 1.12-1.32% in the diameter of the queen cells, 1.13-3.30% in their length and 4.82-27.82% in the total royal jelly production obtained compared to the control group. The conclusion highlights that the use of the biostimulator “Chloramicob” in the feeding of nurse bees leads to an increase in the number of larvae accepted by 7.27-16.36% and in the total royal jelly production by 21.11-48.06% compared to the control group.
