all strongly indicate that thresholds are a meaningful and useful
management tool.

You're absolutely right, Eric.  The concept of thresholds only fails if they 
are used as a magic number that you wait for until you treat your colonies.
They are very useful as predictors if you're on a dangerous trajectory, and 
I believe I covered them well as such in my article in ABJ.
It's not at all hard to adjust them for colony strength by eyeballing.
The most important thing is to use a sampling technique that is accurate and 
appropriate for the season.
