So sorry, after first writing my post, I switched stayers and flyers in the
sentence for clarity, but neglected to change a key word!
Please allow me to try again : )
The bees that STAYED, in 9 out of 10 reps had substantially HIGHER mite
loads than those that flew off  -- 40% higher, on average.

One would have assumed as much, since there are a few (actually,
surprisingly few) studies that have measured the infestation rate of nurse
bees compared to older workers.
This fall I ran a bunch of experiments to question most of my assumptions
about taking bee samples (like which frame to take them from) and
performing alcohol washes (like what percentage of alcohol to use, and how
much agitation is actually necessary).  I'll be publishing my findings in a
series of articles.
