The efficiency of Apifos against varroatosis in bees

The aim of the research was to gauge the efficiency of Apifos (strips conta ining 60 mg of bromfenvinphose) in fighting varrosa. The highest efficiency , almost 94%, was noted in families of group I, where two strips of Apifos were situated near the feeder, less in group II - strips were placed in the bottom chamber, between cs situated furthest from each other (84.33%). The lowest efficiency was noted in families of group III, where Apifos strips were located nest to one another in the top and bottom chamber (73.87%) and zero efficiency was observed in bee families where strips were placed in t he top chamber between the last and next last frame on the side opposite to the feeder, The efficiency of Apivarol AS against varrosis was high and am ounted almost 90%. The above obtained research results indicate that the level of efficiency a gainst varroatosis is dependent not only on the type of substance used in s trips and its quality, but also strip location.
