Some beekeepers have suggested honeydew as the problem in the current
outbreak of disappearing disease.
Maybe the list can help out here -- to the best of our knowledge, honeydew
may be a poor nutrient, but isn't toxic. There's a complex set of issues,
including microbes in the gut, that all interplay and may eventually kill bees.
But, at least in CA, the bees collapse rather slowly, over the winter, when
they are living on a high enough percentage of honeydew in their stored food.
We've now documented the bee loss problem in 10 states, many of which DO NOT
have a fall honeydew flow. Some areas of CA apparently do get a late season
honeydew.
Based on the reports that we have, the yards that we visited, the colony
collapse is rapid - 2 to 3 weeks or less. And, we've got some clues that
suggest that the current problem can be passed to other colonies, yards -- nearby
colonies may show the problem, while bees far away also show it (when
affected colonies are brought in and placed near local colonies - all of the
colonies collapse).
So, unless someone has convincing evidence that this is due to honeydew,
we're still looking for the cause. Please don't decide NOT to fill out our
survey, because you think you know the answer. You may be right -- and we'd be
glad to find out, but you may be wrong, and lack of participation will no help
us sort this out.
