That is what I have been saying all along. The existence of localized or
naturalized bees has never been proved to my satisfaction. There are so many
migratory bee operations you can't avoid the influx of their bees and their
pests. 

Witness how fast varroa populated the country. The fact that all honey bee
colonies got varroa in such a short time almost certainly confirms the idea
that every colony in the US is within the flight distance of somebody else's
bees.
