Diverse parasites and pathogens affect productivity and survival of honey bees. Plant secondary metabolites are potentialalternative treatments, however, their effect has been little studied on microsporidian diseases. Furthermore, thereis poor information about the toxicity resulting from prolonged oral administration of these substances to bees. In thisresearch, we evaluated in vivo effects of different essential oils and main components (MCs) on bee survival and Nosemaceranae development under an ad libitum non-choice regimen. Substances administered on sucrose syrup to newlyemerged bees at different concentrations were avidly consumed and caused different survival performances. Nevertheless,sublethal doses of substances did not control the parasite.
