>Pulling bees apart to detect TM is laborious and although it was de
rigeur before varroa, I don't know if anyone does it anymore.
Nonetheless, TM is still here and still doing the same harm it always
did - AFAIK, but is masked by other concerns.
I sent bees from deadouts in each yard [4] this spring. Beltsville said no TM. I do not treat for them, use oxalic vapor for mites and my own examinations under a microscope have never detected one. I do use VSH type queens in all my hives. I believe that may be the reason I don't see them.
