Abstract - Low doses of fluvalinate were tested for control of Varroa jacobsoni in honey bee (Apis mellifera) colonies in Yugoslavia. When presented to colonies as a smoke strip fumigant, low dosages (0.0025 g per colony on 3 occasions) provided excellent control of V jacobsoni. In comparison with amitraz as a fumigant or in an aerosol or fluvalinate in an aerosol, the application of fluvalinate as a fumigant killed a greater percentage of mites. Mite mortality occurred mainly in the first 90 min after treatment but continued throughout the first 24 h after treatment at significant levels.
