Abstract
The study showed that when using the wet and dry grafting methods investigated using the Duncan multiple range test , the existence of significant differences at the 0.05 level of probability that the dry method was superior to the wet method in achieving the highest numbers of successfully inoculated wax cups as this method resulted in the highest average of successfully inoculated wax cups at the date of 25 / 4 and obtaining the average (55.33) wax cup / hive while the lowest number of successful inoculated cups was at the date of 25 / 8, which gave the average of (4.67) wax cup / hive . The dry method from the other and resulted in the highest average of successfully inoculated wax cups on 10 / 4 with an average of ( 50.00) wax cup / hive while it resulted in lowest grafting on 10 / 8 , 25 / 8 , 10 / 9 as it resulted in an average of (0.00) wax cup / hive, the results also show that the best periods to obtain a the highest number of successful wax cups are in the breeding months of April and the March and the first third of June as it was the best of the rest of the months of the year, which was used both types of grafting due to the improved food availability and appropriate temperature.
