>that non VSH bees prevail in the general population because they are
maintained with acaricides.
This has been in the back of my mind following this discussion. The use of
acaricides removes the selective pressure required to select for the
advantages of the VSH, hygienic, or other mite resistant trait.
I don't know that there is practical method of maintaining the selective
pressure without sacrificing a large portion of your bees a la Kirk
Webster, John Kefuss, Chris Baldwin, etc.
