The comparison of bees wintering in dadan-blat and in multistorey bottomless hives

Abstract

The aim was to evaluate the pros and cons of bee wintering compared Dadan-Blat and multistorey bottomless hives. The object of research was the bees. Investigations were carried out Algirdas Amšiejaus apiary for the period 2010-2013. All bee mothers were Algirdas Amšiejaus breeding apiary. Maternal race - Apis mellifera carnica. Bee wintering evaluated by the following indicators: 1. Consumed during the winter the amount of food. 2. The number of dead bees in the winter. 3. Bee diarrhoea. 4. Hive humidity. 5. Pupae in spring The data obtained showed that bee wintering indicators for the bees overwinter better in Dadan-Blat hives. They are wintering bees three indicators (the amount of food consumed, amount of brood, diarrhoea point) is better than multistorey hives. But in multi-storey hives bee colonies perished 24.5 % less than in Dadan-Blat hives. Multistorey hives humidity was 8.0 %. Due to the open bottom of the bees hibernate drier slots. According to the bee wintering indicators show that the bees overwinter better in Dadan-Blat hives. They are wintering bees three indicators (the amount of food consumed, amount of brood, diarrhoea point) is better.
