During 1995/96, 1996/97, and 1997/98 wintering of hybrid bees (Apis mellifica L.) in sixteen-frame hives was investigated. Experiments were carried out in two variants : 10 hives with lower bee-entrances were left to control and 10 hives with upper bee-entrances were opened during winter season. The obtained data on the wintering indicate that during wintering bees from the hives with upper bee-entrances saved up to 1,91 kg of food. A very strong correlation (r=0,99) was found between the used up food and the relative air humidity in the control hives.
