Abstract :
Comparative studies were carried out between Carniolan, Carniolan hybrid, Italian hybrid and Italian according to their activities in propolis gathering in a whole year under temperature and relative humidity conditions. The results showed that the highest amount of propolis in a whole year was (118.1 g/colony/year) by Carniolan hybrid colonies, while the lowest amount of propolis was (81.5 g/colony/year) by Italian hybrid colonies. The highest amounts of propolis were collected in Summer and Autumn from all races, while the lowest amount of propolis was collected during Winter season. Statistical analysis showed that highly significant differences between propolis amounts in different races. Generally, Carniolan race and its hybrid were more active in propolis gathering than Italian and its hybrid.
