    Default Do diseases usually infect queens?

    I understand that it is rare to find a queen with varroa on her, so are they subject to the viruses which are vectored by varroa?

    Yes, queens have virus infections just as workers do. They can be infected through feeding by infected nurse bees, and if I remember correctly, mating with infected drones. They usually are superseded before the visual symptoms occur. If you do a search for virus infections of honey bee queens, you will find a few studies by Chen and others.

    That is pretty much what I expected. Pretty much explains the reports of high supercedure rates doesn't it? It also implies a need for caution when combining under performing colonies.

    The queens can also pass the viruses to their offspring, they have found DWV in the eggs. I no longer try to save weak colonies by joining them with other colonies. If adding brood from a strong colony doesn't help I just write them off.
