Varroa destructor is the most harmful and widespread parasite that spreads disease in bees. Eucalyptus spp essential oils (EOs) have proved effective against V. destructor. Additionally, Lavender EOs treatment has caused mite mortality rates of 95% to 97% for same parasite. In this study, 20 mL each oil or placebo were distributed on two sheets papier-mâché located frames brood chamber inside hive. The miticidal effects Lavandula angustifolia globulus analysed. Parasitic load fall evaluated under field conditions. mean infestation rate obtained from three groups at beginning study was less than 3.6%. Then, increased gradually group until day 36. treated with L. lower control by over per cent never exceeded 10%; differences between statistically significant (P<0.05). conclusion, EO provided starting second dose. However, E. did not show a consistent control. Further studies should consider evaluation different weather conditions other delivery systems.
