This would not explain the CCD cases found in non-migratory operations,
nor would it explain the cases of CCD found among East coast migratory
operations. 

The East coast operations do not move hives in the cold, but instead, 
move north "with the blooms", and move south well before bees are 
completely confined by cold.

As an example of a non-migratory operation that reported CCD among their
yards, I can offer Dr. Dewey Caron of U DE.  He's a little hard to 
dismiss as someone who might have been mistaken, or might have 
misdiagnosed some other problem as "CCD".

It looks like the hypothesis, rather than the diesel fuel, needs 
additional refining.  :)
