Abstract :This study was carried out to determine the effects of oxalic acid insert ignore into journalissuearticles values(OA); on reducing Varroa mite insert ignore into journalissuearticles values(Varroa destructor); populations in honeybee insert ignore into journalissuearticles values(Apis mellifera L.); colonies in the fall. Twenty honeybee colonies, in wooden Langstroth hives, were used in this experiment. Average Varroa infestation levels insert ignore into journalissuearticles values(%); of the OA and control groups were 25.87% and 24.57% on adult workers before the treatments. The OA treatments were applied twice, on 3 November and 13 November 2006. Average Varroa infestation levels were 5.24% and 31.43% after the first application and 2.87% and 41.74% after the second application in the OA and control groups, respectively. Average efficacy of OA was 93.40%. No queens were lost, and there was no brood or adult honeybee mortality in any of the colonies during the experiment.
