The paper presents the results of the study on the effects of Chlorella vulgaris suspension on growth performance, development and honey yield of bee colonies (Apis mellifera carpatica). A series of experiments were carried out with worker bees and nurse bees fed, in several steps, with one liter (per bee colony) of suspension of Chlorella Vulgaris with sugar 1:1. During the active season, the control of bee colonies was performed every 12 days up to the main harvest from black locust. The results revealed that Chlorella supplement had a beneficial effect on the development of bee colonies. The number of capped brood in Chlorella supplemented groups was 22,4% more than in the control. Honey yield also increased by 17.0% as compared with the control group, fed with sugar syrup. Dietary Chlorella supplementation to nurse bees contributed to a better development of queen cells, influencing their mass, length and diameter. For stimulating the development of bee colonies in the spring, when there is a lack of natural forage (nectar and pollen), it is recommended to use the suspension of Chlorella Vulgaris with sugar 1:1, one liter every 12 days; in the period of queen rearing _ from the transplanting of larvae to the capping of queen cells, (5 days).
