This sort of treatment has been tried by APHIS in
New York, New Jersey, and Chicago, so APHIS should
have some sort of data on the potential for detectable
levels in nectar and pollen.
The good news is that ONLY maples are being injected with
imidacloprid in Worcester for now, at least according to
the Telegram:

Maples bloom really, really early. So early, most beekeepers
don't even notice the subtle color change in the trees because
they are too busy shoveling snow.
Getting any sort of crop from maple is impossible most years
due simply to weather that keeps the bees grounded during the
entire bloom period. (My experience was a maximum of one in
about every four years in VA, and I've yet to attempt it in
New York.)
So, all that needs to be done is to warn off the tiny number of
beekeepers with the experience, skills, and motivation to work
their bees in the snow to get a crop of maple honey. Perhaps
they should not make the attempt until more is known about the
impact of having a maple tree mainlining imidacloprid.
Further, there appears to be enough time between the blooming
of the hardwoods that the beetle likes and the spring emergence
of the first beetles to prompt one to wonder why any trees
would need to be injected until after the trees bloom.
So, Dean himself has nothing to worry about, but beekeepers
near Wooster who deploy feeders in early spring and fly
purebred pedigree queens may want to ask about bloom dates
versus treatment dates.
