This does not address my concern, because as I said, although
you apparently don't believe it, I am not suggesting that this
is the cause of CCD.  I chose the subject line of this thread
very poorly it seems.  I am saying that there might be some
connection, but it certainly is not my major concern since 
I have not experienced CCD to my knowledge.  My concern, is, as
I stated, that I can not find any test results looking for 
possible residues in corn syrup.  Some test results is what 
will address my concerns.  You have impressed me many times 
with your ability to source information on the internet and
other places.  Can you source any test results?   How many tons
of this are fed to bees every year;  surely somebody is testing?

No argument:  Please note the sunflowers had high levels of 
imidacloprid (the seed was treated with it, and it was intended
to turn the plant toxic to insects)

And this is the symptom of lower levels of poisoning.

Chilling and other brood problems such as chalkbrood and EFB
will naturally result from depopulation.

I know you pride yourself on your logic, so please consider that point
4 is inconsistent with point 2.  If a colony has a lot of brood and few
bees it cannot be collapsing over months.  Brood does not last that long.
Several frames of brood with a handful of bees is the symptom of rapid
collapse.  However, the queen could survive for a long time with a few
young bees.  The trembling threshold does not need to be reached for 
the confusion threshold to cause depopulation.
