Strips of Amitraz against the mite Varroa jacobsoni Oudemans in hives of Apis mellifera L.
Abstract
Cuban plastic strips containing 13,2 mg Amitraz (amidine) -commercially patented as Apizel- were evaluated in their effectiveness against Varroa jacobsoni Oudemans acarus in Apis mellifera beehives. These strips were compared to French ones, commercially named Apivar, which contain 500 mg of an active substance from the manufacturer's instructions, 8 Apizel (Apiary A) strips (105,6 mg) were applied to double beehives and 4 strips (52,8 mg) to single beehives. As indicated, two Apivar (Apiary B) strips were randomly placed in each hive (1000 mg). The 8 beehives from Apiary A showed an initial infectation general rate of 12,86%; but after six weeks of treatment, this value decreased to 2,90% (77,45% decrease), while Apiary B initial infectation general rate of 2,41% was only reduced to 0,11% (95,43% decrease) during the same time. It is evident that, although initial rates are highly different, French strips effectiveness can be evaluated as good, but Cuban strips did not achieve an acceptable effect due to a lower dosage of the active substance used.
