Aim of the present study was to evaluate the in vitro antimycotic activity of 17 chemically defined essential oils (EOs) both alone and as a mixture, against agents responsible for stonebrood caused by Aspergillus flavus, and chalkbrood caused by Ascosphaera apis in European honeybees. Cinnamomum zeylanicum yielded the lowest MIC value against A. flavus, but was not effective against A. apis, while Litsea cubeba and Pelargonium graveolens appeared to be effective against all checked fungi. Aspergillus niger showed the lower sensitivity. Two mixtures composed by L. cubeba, C. zeylanicum and Cymbopogon flexuosus (M1) and by L. cubeba, C. zeylanicum, P. graveolens and C. flexuosus (M2), respectively, were tested, both resulting effective. The components of M1 showed a synergistic effect. The use of mixtures allowed to decrease the total amount of EOs. The use of these products could be of interest for an alternative natural approach in honeybee disease management. [GRAPHICS] .
