| Popis: | The aim was to clarify some aspects of the biological evolution of bee families under the influence of environmental temperature and subsequent reporting of behavioural change. The experiment was conducted in a private apiary in Giurgiu County, during three years, in May and June. The biological material was represented by 14 strong colonies. The bees were maintained in vertical hives. The biological evolution of bees was analyzed in population growth period. Bee indicators were the following: egg-laying activities of the queen bee, honey bee flight activity, gentleness of bees, swarming behaviour. It was found out that by lowering the temperature with about 3°C, the number of eggs laid decreased by 11%, the differences being significant (p ≤ 0.05). In rainy years, it has been a tendency of swarming, 41.7% of bee colonies showing this trend. The irritability of bees was significantly higher in periods of warm temperatures, this occurring in the early morning hours. |
