<<But is there any research, eyewitness accounts or scientific evidence that
bumblebees are vectors, or carriers, of varroa or tracheal mites?>>
Answered my own question in the archives (the answer is yes), but nobody has
had anything to say about the issue for over 5 years (since 1995). Is there
any new research into the possibility of bumblebees, wasps and other critters
carrying varroa into honey bee colonies?
