Harmen,
How do we breed our disease resistant bees?
Steve Taber began this business in 1979, to breed a Disease Resistant stock of bees which was "hygienic" in its ability to clean up American Foulbrood. He inseminated a breeder with just one drone, from another line with the same characteristics. In this unique way, selection could be made in one generation to change the behavior of the entire resulting line. This stock was later shown to also be resistant to Chalkbrood Disease. Today from research in Germany and Minnesota, we know this behavior is also involved in resistance to Varroa mites. Our first breeding step with any new stock is to test and find this trait. The queens and their offspring will all have hygienic Disease Resistance
