This would be in contradiction to a mountain of evidence:

Large mite populations have been responsible for
vectoring bee viruses between honey bees. The viruses,
which previously spread relatively slowly and caused
colony mortality extremely rarely, are now thought to
be responsible for the world-wide death of millions of
mite-infested honey bee colonies.
