The study was conducted in the province of Babylon in one of the apiaries in the village of Al-Mahnawiya. The aim of the study was to evaluate the efficacy of the hexane extract of Morinca and rosemary plants on the rate of destruction of the Varroa parasite and its effect on honey bees. The concentrations used for both extracts were (1, 1.5, 2) g/cell, respectively. The results showed the superiority of the hexane extract of the Morinca plant at a concentration of 2 g/cell, 1 g/cell, and 1.5 g/cell over rosemary extract at a concentration of 2 g/cell, 1 g/cell, and 1.5 g/cell, with a significant difference between all concentrations and for all time periods. The highest rate of death for Varroa at a concentration of 2 g/cell was 22.16 after 48 hours, and the lowest rate of death for Varroa after 144 hours for rosemary extract at a concentration of 1 g/cell 0.66. As for the effect of hexane extract of moringa and rosemary plants on honey bees, it was the highest effect For Morinca hexane extract, after 40 hours, at a concentration of 2 g/cell, it reached 2.41, and the least effect was for the hexane extract of rosemary plants, after 64 hours, it was 0.10 at a concentration of 1 g/cell. The results indicated that as the time increases, the effect decreases.
