| Abstract | ||
| The variations exist in acceptance percentage of grafted larvae, emergence percentage and weight of virgin queens according to different grafted bar level and queen cells position of local carniolan race (Apis mellifera carnica) in Manzala region were investigated. No significant differences were found in the acceptance percentage, emergence percentage and weight of virgin queen for the three bar levels. However, the acceptance percentage was positively affected by minimum temperature for the top bar. The weight of virgin queens was positively affected by the change in minimum temperature on all bar levels. On the other hand, the tested parameters were significantly increased on the middle position of bar than on the edge. In spite of the percentages of acceptance and queen emergence were positively affected by the ambient temperatures elements they were more pronounced factors on the weight of emerged queens on the edge position. | ||
