I have heard a good deal of researchers comment on whats been found in comb samples taken from CCD hives. Seems contaminated comb is found about everywhere. At least three researchers at the Pennsylvania State Bee Association fall meeting a few weeks back made comments on fluvalinate in particular, as well as about everything else, found at very high levels in CCD comb.
I'm just throwing out an idea, but I could see this happening just the same. That at the end of the day, neonicotinoids will be found to be some nasty stuff. Something to be concerned with, something to take guard against. But its the compounding effect that this chemical has in combination with other chemicals, some illegally placed into hives, that turn this into a much deadlier concoction that made the losses possible.
Yes, some will say that there are examples of bees on new comb being effected by CCD. Seems the dots and ducks are not clear on this CCD thing no matter what we look at. Nothing connects, and nothing is lined up perfectly.
But this is one way that along with any finger pointing at the makers of neonicotinoid products, beekeepers and other chemical companies, blame will be spread out, liability lessened, and nobody wins.
There are many examples of one drug or chemical having little negative impact. But add another, or even another, and the mixture turns deadly.
Researchers are now tracking hives as they migrate across the pollination spectrum, taking samples, noting the chemicals, the sprays, and the impact of everything that could effect hives.
But why? Isolating one particular chemical should be easy enough. But it seems that besides neonicotinoids, there seems to be contributing factors or compounding contaminates that some are now focused on.
So will there be no one single source to blame? That perhaps neonicotinoids are lesser of a danger by themselves, but far deadlier when mixed with other chemicals?
I said many months ago that not one clear item will be singled out. I still thinks thats true.
