The Short Version
The Major Problems Facing Bees and Beekeepers
Number one is varroa. Varroa changed the virus dynamics within the colony. If either the bees or the beekeeper don't keep the varroa infestation rate down to fewer than 5 mites per 100 bees, colonies start to suffer. At about 15 mites per 100, viruses go... | The Short Version - Scientific Beekeeping | https://scientificbeekeeping.com/the-short-version/ |

DWV sampling instructions
Dear U.S. beekeeper,
Recent studies by Dr. Stephen Martin and associates have found that there is apparently a benign form of DWV that can out compete the virulent form, thus allowing colonies to survive despite varroa infestation.
If this is true, it raises the possibility that we may be a... | DWV sampling instructions - Scientific Beekeeping | https://scientificbeekeeping.com/dwv-sampling-instructions/ |
