Braine-le-Château, August 2014. We have finished the Varroa-brood-counting. In total more than 20 colonies were identified with high levels of Varroa resistance !!!
These colonies had levels equal to or higher than 75% Varroa Sensitive Hygiene (VSH) behavior. Half of the colonies are from European honeybee lines and half of the colonies have a mainly US origin (USDA, with proven VSH background). The colonies with 75% VSH had significantly lower (reproducing) mite levels, the 100% VSH colonies had removed almost all of the mites!
A press release will be available after review of the data by the Scientific Committee and securing offspring of these valuable queens. As the weather in Northern Europe might not be good enough to breed viable daughter-queens, colonies will also be transported to Spain.
