Abstract. All major processes in the bee colony are closely related to nectariferous vegetation in the area. Oviparous activity of queen bees is directly dependent on the flow of nectar and pollen in the bee colony. When it rises it leads to increase of the oviparous activity of queens, and thus increases the power of the colony. Stimulating feeding with sugar syrup in the absence of pollen flow has little effect on the laying activity of the queens, as the syrup with biologically active substances which are necessary for bees and queens. This paper presents a research on the addition of extract of Tribulus terrestris L. as invert sugar syrup, by which we import some of the biologically active substances needed by bees and bee stimulating oviparous activity of the queen bees.
