Great observation.

We see this in all pathogen/host events in the real world. Cyclic
catastrophic events followed by a long build up then another crash. Bees
have this problem- disappearing disease is a classic. And I would not rule
Tracheal out for a comback.

And we continually miss the real issue, which is not Varroa but the
pathogens it carries. Dogs are "tick resistant" but not RM Spotted fever
resistant. If you have Varroa without virus, you have "resistant" bees
