Abstract - Four miticides in various formulations and concentrations were applied in a fall treatment program to honey bee colonies infested with Acarapis woodi. The miticides tested were menthol, Amitraz, fluvalinate (Apistan®), and cymiazole (Apitol®). None of the miticides significantly reduced mite prevalence in treated colonies relative to the control treatment. Additional studies should be undertaken in temperate climates to determine whether the efficacy of the miticides tested in this study can be improved by administering them at other time during the year or by adjusting dosages rates to improve their efficacy when applied to infested colonies during a fall management program.

Key words: Acarapis woodi / miticide / chemical control / efficacy
