Bee J. 135(12): 825-833. "In every case, resistance in bees appears to be associated with the failure of female mites to produce progeny after they enter a brood cell (non-reproduction of mites). Exchanged brood between resistant and susceptible hives: "..Non-reproduction of mites was controlled by events that preceded their entering the cell. Brood from the resistant colony supported a high frequency of mite reproduction (82%) when infested with mites in the susceptible colony. Conversely, brood from the susceptible colony had a low frequency of mite reproduction (36%) when infested with mites from the resistant colony" [What they were really seeing was the effect of presence or absence of essential oils (in nectar, propolis, or whatever) in the respective hives].
