Thanks Jim for mentioning my name. Though I worked on my article for many weeks I claim no expertise. I can vouch for the experience of the sampling team that worked with Dennis vanEnglesdorp. There were 2 veteran FL bee inspectors. (You have read their articles at some point)There were 3 serious beekeepers with over 1,000 hives And Dave Hackenberg (40 yrs experience)and I. Samples of comb, honey, bees and brood were organized according to a map made of the bee-yard. Some were frozen some in alcohol and some in vials. One yard had bees in 4 categories. Dead, Dying, Recovering and healthy. Weeks before they had been all healthy. The yard had 250 colonies. 100 dead and the rest equally divided. Samples noted these categories too. At the same time, Jerry Bromenschenk, having just left FL was in CA with a team of 5 of his regular employees doing the same thing.
I have a picture I will post some day of the dead hives, standing on end, like tombstones. I lost my temper once on this list because people were going round and round about whether CCD exists or not. Go tell the owners (at least 5) of the thousands of hives we checked. These guys know what a sick hive looks like. They didn't get where they are by being dumb.
When I started writing, I examined a concept found in nature, known as a die-off. That was the title (Apr. or May 07 of ABJ). I admit it's a goofy idea but what if the bees have a larger than a yearly cycle where they "die-off" every so often as a way to eliminate pests and disease. We of course maintain the use of old comb to undermine this "purification."
I think it was you who posted a list of die-offs on another list that I admired. Could you re-post it here?
