I'm no expert in pesticide resistance, but David M. Noetzel, Extension
Entomologist Emeritus from University of Minnesota, suggests in American Bee
Journal (December 1995, page 791) that HIGH doses of fluvalinate would lead
to faster resistance than lower doses.
 
The thinking behind this is that killing 99% of the mites provides more
selection for resistance than, say, a mite treatment that only kills off 80%.
 
Sure wish we could kill 100% & be done with them!
