Effect of Different Concentrations of Oxalic Acid in the Fallen Mites Mean on the Hive Board During Spring and Early Summer Season
Keywords:Varroa , Oxalic Acid , Mite, relative effectiveness, fall mite number, relative efficiency
The results of the current study showed that the lowest mean of falling mite on the hive board was recorded in the 4.2% concentration treatment which amounted to 0.16 mite compared with the control treatment which recorded the highest mean which was amounted to 4.69 mite. As for the mean number of the expected mite inside the hive, the highest mean was recorded in the control treatment which amounted to 468.6 mite compared with the 4.2% concentration treatment in which the lowest mean was recorded, which amounted to 15.69 mite. As for the relative effectiveness, the highest average was recorded in the control treatment, which amounted to 66.67%, compared with the lowest mean of the 4.2% concentration treatment, which amounted to 17.75%. The above results were reflected in the treatment efficiency to regest the highest mean of efficiency in the 4.2% concentration treatment with a mean of 60.47% compared with the lowest average in the control treatment of 9.47%, knowing that the statistical analysis showed the moral superiority of all oxalic acid treatments over the control treatment.
