Comparative Evaluation of Four Honeybee Races According To Pollen Storage and Worker Brood Rearing Activities Under Natural Conditions
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2017, Vol 12, Issue 1
Abstract
This comparative study was carried out between Carniolan, Carniolan hybrid, Italian and Italian hybrid races of Apis mellifera to evaluate their workers brood rearing and pollen storage activities during a whole year under the natural temperature and relative humidity conditions. The largest amounts of stored pollen and workers brood were recorded in spring and the lowest were in winter for all races. It was observed two peaks of stored pollen amounts in May (clover season) and August (maize season), while, the lowest amounts were recorded in December. There were significant positive correlations between the temperature and amounts of stored pollen in Italian hybrid and Carniolan races, while, Italian and Italian hybrid races significantly and negatively correlated with relative humidity. There was two peaks in workers brood rearing activity in March and November. It had a significant negative correlation with relative humidity, whereas, there was no correlation with temperature. Perhaps, it is due to the internal and external factors affect all activities of honey bees. The Italian race was the most efficient in pollen storage and workers brood rearing activities, as well as the Italian and Carniolan races surpassed their hybrids.
