Got me confused on that one. How did they know they did not have 
tracheal before the collapse but suddenly had high levels afterward? It 
does  not make sense.

Tracheal mites tend to be the forgotten mites since everyone's bees are 
now immune to them. Only problem is we have many colonies in Maine that 
collapse from Tracheal and all are from hives that "do not have 
Tracheal", at least before the samples were sent in. I still think that 
many Varroa problems are actually Tracheal. It is just easier to see a 
Varroa mite on a drone pupa, than to pop off a head and look through a 
scope to find Tracheal.
