It's not just the honey bee that evolves to avoid losses due to Varroa: the viruses do also!


Here in the UK a very experienced beekeeper, Ron Hoskins, together with other beekeepers in his locality, have gone without treating their bees against Varroa for many years and it was assumed that they/Darwin had successfully selected a resistant strain of bee although Varroa were still present. Now it appears that the usual strain of Deformed Wing Virus (Type A) has been replaced by a less virulent Type B.  A third type (C) has also been discovered elsewhere.
