Why some honeybees have much higher levels of Varroa?
Due to the lack of understanding bees, the beekeeping world is always interesting, as if it were infinitely deep.
By Sebastian Owen:
Beekeepers often wonder why some honeybee colonies have much higher levels of Varroa infestation than others in the same apiary. In fact no two colonies ever seem to have the same level of infestation, so that requires the trialling of new treatments to be very scientific. Rigorous testing of treatment efficacy and repeatability are key features of the registration process.
Max Watkins said: “Few things are certain, but you can always be sure that infestation levels are never equal between colonies in the same apiary.”
