The residues of fluvalinate accumulated in the wax promote the selection and development of Varroa jacobsoni resistance to fluvalinate activity. Probably Varroa jacobsoni will be resistant to other acaricidal synthetic pyrethroids (due to cross-resistance). The possibilities of using for honey-bee protection the inserted to hives strips, containing known pesticides, such as amitraz, malathion and bromfenvinphos, which have different, than synthetic pyretroids, mode of biological action, and which are suitable to overcome fluvalinate resistant mites were tested in Poland. The high varroacidal effectiveness of the strips with above mentioned pesticides during 6 weeks exposition was found. However, amitraz, at the concentration of 5% in PVC strip, was decomposed after 5 months of storage. Malathion at the same concentration is not quite safe for bees. The promising results with bromfenvinphos incorporated in PVC strip (5%), as well as in the form of microlayer (50-60 mg a.i.) on PE strip were obtained (the average varroacidal effectiveness achieved 99%). The dorsal bromfenvinphos apitoxicity LD50 was 7310 ng/bee.
