Before anyone gets the wrong idea here, I am not advocating heavy use of pesticides. The research I'm working on is funded by farmers' groups and cooperatives, not seed or chemical companies. (Seed and chemical companies do contribute some of their products, but some of their products are purchased through the same outlets that everyone else uses as a control -- you know, so the "freebies" aren't really super formulations just to show how effective their products are.). . .but I also believe that if the issue wasn't important to you, you wouldn't be expressing your views and knowlege. I could be wrong. Just an assumption. -hummingberd
Really, the reason I've posted so often against the idea that pesticides are to blame is that I'm firmly convinced pesticides are NOT to blame for CCD. I've seen plenty of pesticide poisonings of bees, including poisonings by imidacloprid and other neonicotinoids, and the evidence I'm seen doesn't match at all the descriptions of CCD.
I suspect CCD is a combination of factors, all coinciding occasionally to create the losses we call "CCD." Environmental stress, pathogens (new or the same ol' ones), perhaps malnutrition (which may be caused by environmental stress), parasites, etc.
I wish the cause of CCD was something as simple as "poisoning by neonicotinoids." I doubt it's simple at all. The fact the researchers looking into CCD haven't been able to pinpoint a cause yet suggests the cause isn't simple at all.
