Hi Stan,

I would be suspect of this report, mainly due to the claims that
imidacloprid causes the bees to become disoriented and not able to find
their way back to their hives.  It the bees aren't getting home, how would
they contaminate the hive?  However, these are just my shoot from the hip
thoughts on the topic.  I too would be interested to see any print that may
substaitiate (or not) what you heard.

Cheers,
Aaron
