Varroa resistant bees
The United States Department of Agriculture (USDA) has shown that it is possible to select honey bees with Varroa Sensitive Hygiene (VSH) behavior: these bees can detect reproducing Varroa in brood. As these VSH bees remove the infested brood, no Varroa offspring is produced. Selection has only been limited to this trait and no resources were available yet to structurally integrate this trait in a broader base of the honey bee population.
The next step in the breeding program, starting in the 2015 season, will be to further select towards 100% VSH in the EU breeding stock. Once this level is reached, normal sized, multi-drone colonies will be created and thoroughly tested on other important traits like honey production, gentleness and swarming tendency. Also the selection has to be done in as many different lines of honey bees as possible to ensure a rich biodiversity and to enable its broad application in the beekeeper community worldwide. >>>Read more>>>
