I'm curious about this statement, Bob.  What is your source of information?
 Are you basing it on the following sentence from the paper?
"The loss of imidacloprid-
treated hives in this study is also highly unlikely
due to pathogen infection since the presence of neither
Nosema nor a large number of Varroa mites was
observed in hives during the summer and fall seasons."

Bob, in your experience as a commercial beekeeper, in colonies having a
minimum of 14 frames of brood in May, but not treated in any way for mites
until Oct 5, and then treated with Apistan, would you expect those colonies
to survive the winter?
