Ingemar Fries - Evaluation of Varroa mite tolerance (Popular version for publication)

Summary
Breeding honey bees for specific defined characteristics to obtain varroa mite tolerant bees appears to be difficult. Instead it is suggested that the daily rate of mite population growth during optimal mite breeding conditions is used to determine the breeding value for mite tolerance in evaluated colonies. The precision needed to determine mite population growth will determine if samples of adult bees at different occasions will suffice, or if more detailed measurements of the mite population is required. Threshold levels for mite population densities before mite control is required need to be determined for different geographical regions and foraging conditions.
