>>since many report that amitraz is no longer effective (in their opinion).   This opinion is  so strongly held by some beekeepers that they have contracted studies to search for other treatment options - that's a factual statement, not opinion.

thanks Jerry,

From the perspective of a US beekeeper, or the perspective from a beekeeper outside of the country, is there not some form of government surveillance program set up to track and document cases of disease and pests? I'm sure there is, I have seen American maps highlighting AHB zones, and SHB zones. 

Has there been any work in the US to detect and track Amitraz rVarroa?
