Formic acid: an effective acaricide against Tropilaelaps clareae Delfinado and Baker (Laelaptidae: Acarina) and its effect on the brood and longevity of honey bees


, : Formic acid: an effective acaricide against Tropilaelaps clareae Delfinado and Baker (Laelaptidae: Acarina) and its effect on the brood and longevity of honey bees. American Bee Journal 124(10): 736-738

Each of 3 infested Apis mellifera colonies was fumigated with a daily dose of 5 ml of 85% formic acid; mite populations were effectively reduced in comparison with 3 untreated colonies. Treatment was continued for 6-13 days, the longer treatment period being necessary in the most heavily infested colony.
