American foulbrood (AFB), caused by the spore-forming bacterium Paenibacillus larvae is the most serious disease affecting the larval and pupal stages of honey bees worldwide. Field studies were conducted to evaluate the optimum dosage of tylosin tartrate for controlling infections of American Foulbrood in artificially inoculated colonies. The absence of larvae with clinical symptoms demonstrated that tylosin tartrate at the doses of 1,000 mg and 1,200 mg per colony were effective for the elimination of clinical signs for up to 365 days. On the other hand, cherry jelly used as attractant increased the consumption of the antibiotic. Tylosin tartrate at a doses of 1,000 mg a.i. plus cherry jelly is a valuable tool for controlling AFB infections. KEY WORDS: Paenibacillus larvae, Apis mellifera, tartrato de tilosina, control, American Foulbrood.
