Resistance To Mites
Russian honey bees have an innate resistance to various parasitic mites. This strain occurs in the original native range of the varroa mite, and selective pressure could have favored bees that exhibited aggressive behavior against colony-level mite infestations. Accordingly, experimental research has found that mite populations decline in colonies of pure Russian and of hybrid Russian-Italian bees. The mechanisms through which mite populations are controlled in these colonies include hygienic behavior towards mites, and possibly increased aggression towards mites. Interestingly, Russian stocks also have been shown to resist infection by tracheal mites.
