I seem to recall that the Canadian study showed about the same thing. What
is interesting is that bees on *both* diets started dying around the same
time, in small numbers, and the numbers dying increased each day over time
until they all were dead.
The bees on HFCS died slightly faster, and, as I recall, the difference in
longevity was about 10%, with sucrose being better. The HFCS was of the type
being used widely in Western Canada at the time. In practice, this
difference may or may not be significant, however, I have always preferred
sucrose for wintering, and HFCS for spring feeding.
I think that the Joker in then deck is that, while sucrose syrup deliveries
are always very nearly identical, HFCS batches have the potential to vary
over a range of (acceptable for human food) compositions. A batch analysis
should be available and accompany each HFCS load, but who is knowledgeable
enough to read much past the assertion that it is first grade?
