Tolerant honey bee colonies to American foul brood disease (AFB) using the feeding on the aromatic oils added to sugar syrup before (AFB) bacterial artificially infection were studied. clove , cumin and citrus oils showed different immunity responsiveness against (AFB) disease as oil phenolic components as different. The bacterial spores can't be able to germinate in the haemolymph of honey bee larvae treated with the clove oil which distinguishes by encompass large numbers of the phenolic compounds participate together in the tolerant system against the bacterial infection and persist long period doesn't decrease than seven weeks with higher phagocyte cells were detected in the bee larval haemolymph.
