Objective: To determine the incidence of Acarapis woodi (Rennie) infestation in the tracheae of honey bees (Apis mellifera L.) from colonies not previously treated against the Varroa destructor Anderson and Trueman mite and to discuss the current status of A. woodi in Mexico, based on our observations and historical information. Design/Methodology/Approach: Samples of the thoracic tracheae of honey bees from colonies never treated against the V. destructor mite were taken in search of A. woodi. A 20-worker sample was collected from each colony, preserved in 70% ethanol, and examined no later than two days after the collection. Foraging workers were selected from the lateral combs, the entrance of the hive, and the inner lid, the places where the oldest bees can be found and which have a higher infestation probability trend. The specimens were diagnosed using the dissection technique and observed under a microscope. Results: None of the examined honey bees' tracheae --and therefore none of the colonies-- were infested. Study limitations/Implications: Although only one apiary was studied, a general trend can be observed in Mexico and many other countries in the Americas, especially in tropical and subtropical sites: after a shock wave of A. woodi infestations, they were less frequent, until their detection became very difficult. Findings/Conclusions: The decreasing prevalence of A. woodi has been attributed to climatic preferences and treatments against V. destructor. However, this reduction could be the result of resistance among honey bees. [ABSTRACT FROM AUTHOR] |
