Bees interested people because of honey and wax from ancient times. They were called God’s beetles, God’s workers. Bee products were used for food and medicine. It is advisable for people to eat about 1,8 kg of honey a year. Lately bee farms have been growing stronger. The owners of some apiaries are increasing and modernizing their farms. At the moment 83 thousand families are bred in Lithuania. AIM OF RESEARCH. To establish the dependence of bee mass on the springs of comb, comparing the used discs of the springs of the bee family natural wax combs an artificial combs. METHODS AND CONDITIONS OF RESEARCH. The data for research were collected during the summer of 2006 from bee families bred in Kaunas. In individual variants hives were expanded by discs of springs of natural wax comb and plastic discs of springs of combs. After 8 days after making of cells they were put into well warmed hives or a thermostat for breeding. After 24-36 hours after breeding of bees they were weighed. This experiment will negate the widely spread groundless statements that plastic combs influence the mass of bees. Apirians may safely use plastic wax discs for making combs for bee families. CONCLUSIONS: 1. Artificial discs are more accurate that natural wax discs in all directions of the cells of the comb. 2. Wax discs and artificial comb discs do not influence the mass of bees, as bees bred on such discs during the research showed no significant differences.
