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 Bill Truesdell Bath, Maine *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
