Obtaining of bees products depends on the conditions of maintenance of bees’ families, organization of breeding work,
selection, the honey and the quality of queens obtained from specialized apiary. The goal of the research was to
determine the influence of using the algal suspension "Clorella Vulgaris" in acceptance larvae inoculating for queens
rearing, length, diameter and mass of queen - cells, and mass of mated or none mated queens. There had been noted
that using of algal suspension "Clorella Vulgaris" with sugar in the diet of queens nurse family, contributes the queen -
cells development, influencing the mass, length and diameter of queen - cells. During the active season for lack of
natural harvesting (nectar, pollen), is beneficial to use algal suspension "Clorella Vulgaris" to supplement biological
mixture of sugar 1:1, the amount of one liter per nurses family nutrition, from the moment of larvae inoculation to
capped queen - cells (5 days).
