Resumen:
American Foulbrood (AFB), caused by the spore-forming bacterium Paenibacillus larvae
larvae, is the most serious disease of honeybees. Laboratory and field trials were conducted to evaluate the
effectiveness of essential oils from savory, thyme, lemon-grass, and oregano, and blends of lemon-grass +
thyme; lemon-grass + thyme + oregano + basil, and lemon-grass + thyme + basil in preventing and
controlling infections of AFB in Apis mellifera colonies. The principal components of the essential oils used
were determined by gas chromatography. LD50 values for acute oral toxicity of the oils on adult bees
verified that the essences were non-toxic or slightly toxic. Results from field trials indicate that neither the
essences nor the blends were effective in the elimination of AFB clinical symptoms at any dose formulation
or method of administration tested, whereas tylosin was highly effective in eliminating AFB clinical
symptomsPaenibacillus larvae
