Varroa destructor is the main health problem in the honey bee colonies. Regular monitoring of the Varroa load plays an essential role in determining the right time for treatment of the colony and evaluating the effectiveness of the treatment method. This research aimed at comparative evaluation of the efficacy of alcohol wash and powdered sugar methods to dislodge the Varroa mite from the adult bees' body. Our findings revealed that wash the bees with 75% ethanol dislodged 81.14±3.56% of the mites from their body. In contrast, powdered sugar could dislodge only 54.53±3.56% of the mites from the body of the bees. Therefore, alcohol wash method is more accurate for determining the infestation intensity of the adult honey bees to the Varroa mite.
