Effect of different grafting methods on some important characteristics and mating success of carniolan F1 hybrid queens of honeybee [electronic resource].

Includes references.

This study indicated that, the queen rearing in Carniolan FI hybrid colonies with double grafting gave the highest virgin queen weight of about 203.7 and 200.0 mg followed by 181.7 and 187.3 mg incase of wet grafting, while the lowest weight of virgin queen was 151.7 and 160.4 mg for dry grafting method which reared during the experiment years (2003 & 2004), respectively. The results showed that, the mean percentage of mating success for the queens produced by the different grafting methods (double, wet and dry), were 57.5, 83.3 and 75.0 %, respectively. The lowest mean percentage of mating success was recorded by the queens produced by double and dry grafting methods. The highest success was found by the queens produced by wet grafting method. The mean of preoviposition periods for the emerging virgin queens produced by grafting methods (double, wet and dry) were 10.69, 12.87 and 13.57 days, respectively. From the obtained results the shortest preoviposition periods were founded by double and wet grafting methods, while the longest preoviposition periods were at dry grafting method. The results were statistically analyzed and discussed.
