“…in 10-day chronic toxicity studies, all imidacloprid metabolites revealed
equal toxicity to bees, but the total dose ingested by the bees was about
3000–100 000 times lower than the doses needed to produce the same effect
after acute intoxication.” This information was referenced from another
paper of theirs, it’s this one:

Of course, and did you review that paper?  If you did, you would
immediately notice that it was completely bogus!  All the mortality curves
are the same for all tested compounds regardless of their toxicity!  The
researchers inadvertently starved the bees, as pointed out clearly in a
review of the paper by Schmuck.  One glance at the figures would tell
anyone that the experiment had problems.  Unfortunately, their findings are
widely cited.

It's bee a while, so I can't remember.  It had to do with the fact that IMI
is quickly degraded to CO2, so even the metabolites quickly disappear from
the bees' bodies.  If that is so, it should also eliminate any
"irreversible" binding.  Wouldn't that be true?

I'm glad to hear that it is obvious to you too!  In which situations have
you found that they can't cope with field-realistic doses?
