NEW YORK BEES WITH VARROA RESISTANCE

Here is another case where wild bees in New York have developed resistance to varroa mites.  Initial thoughts are that this is occurring through natural selection.  So the lesson to learned is that feral bees have somehow found a way to survive.  Now if we beekeepers would just stop diluting these good genetics with package queens and their progeny the bees could theoretically develop resistance to varroa.
