I got into a wrangle here a few years back when I reported that there has 
been no improvement in resistance to tracheal mites in US commercial stocks 
over the past decade.  This was in the context of the campaign against 
importing Australian stock.  The argument was being made about how the US 
stock had developed resistance to various things (including tracheal mites) 
and how could offshore bees from a protected environment be expected to 
measure up?

I said, "Hold on there, the evidence is to the contrary.  Baton Rouge has 
been tracking this characteristic", and then I came under some considerable 
calumny -- to the extent that I left the list for a year or so.

Again, recently, I mentioned this same observation in a similar context and 
immediately received some supporting evidence which I present in detail at 
http://www.honeybeeworld.com/diary/articles/tracheal.htm.  (See "March 2010" 
at the bottom).

Shame!  On average, to my eye, things are worse, not better than in 1999 and 
much worse than 2002.
