Airborne particulates is a false equivalency.

I get the feeling you won't be happy until everyone admits your particular point of interest is the culprit, which isn't exactly a scientific method either. It's fine to look at every possible candidate. It's not fine to decide that's the culprit when it's not even present in many regions of interest.

Also, if neonics are the culprit, that should be very easy to demonstrate -- you should be able to reliably induce CCD in fairly short order just by isolating a hive with a treated food source.

Well, yes it is, since it doesn't have an infinite half-life and doesn't move around by itself. You're certainly not going to find it used in Montana wheatfields, yet CCD has affected bees here as well... so now what to blame?? Indeed, most of our acreage is never treated with anything, being non-arable grazing land or wilderness. Hasn't helped bees any.

I'd guess in addition to the viral and fungal agents that when they occur together have been determined as CCD causes already, there might be a genetic susceptibility in some lines of bees, but far as I know that hasn't been looked at yet.

I'm reminded that many a time, some OMG-Death-Chemical reaction has proven to in fact be due to a genetic defect. Frex, see MDR1 (multi-drug resistance gene) in dogs. Nope, it wasn't ivermectin causing illness and death; it was a genetic defect.

"Neonicotinoids in bees: a review on concentrations, side-effects and risk assessment"
http://www.ncbi.nlm.nih.gov/pm...

"Many lethal and sublethal effects of neonicotinoid insecticides on bees have been described in laboratory studies, however, no effects were observed in field studies with field-realistic dosages."

As they say there's need for further study regarding synergistic effects and the like. But real exposure effects in the field are what counts, not just laboratory findings. Otherwise it's like finding that table salt is OMG-toxic as studied in the lab, even tho we know it's safe in normal realworld use.

Honeybees are technically an invasive species in North America; they were imported, not native. There are numerous other species, including small native bees, that did the pollination work before honeybees came along. Far as I have heard, populations of these native bees have not been affected by CCD.

Neonicotinoids are relatively expensive (4 years ago, Imidacloprid was $25/pound, about 5x the cost of permethins), and I'd guess despite being about a quarter of the insecticide market, that in ag they are probably not used outside of the fairly limited areas that grow fruits and vegetables -- as those crops have a better profit margin. Yet CCD has been seen very widely, including in areas where there isn't any row-crop agriculture.

Anecdotally, I've used Imidacloprid to control desert stink beetles, and did not observe any issues with my wild honeybees (who frequented the same areas, cuz that's where the water was).

The scare over DDT was manufactured. Silent Spring (which I read, back when it was new) was mostly fiction and has been discredited, yet it influenced a whole generation of environmentalism -- that, not truth, was its point and intent. Some estimates put malaria deaths due to ending use of DDT in the millions. Meanwhile, the connection with condor populations was at best tenuous.

Actually there's a pretty good trail being laid down:

Not only that, but per this article (with stats), bee populations are stable to increasing despite CCD:

http://www.perc.org/articles/e...

The amount of honey being produced is a good indicator, given you can't make honey without bees.

This won't load for me but I imagine it goes into more detail:

And actually, you can demonstrate 'insanity' in any wild colony with an aging queen -- the bees become aggressive at greater and greater distances from the hive. I watched this with a wild colony that had taken up residence in the wall of a barn. For the first three years, they were 'gentle' (not concerned about intruders) -- to the point that you could actually poke around in their entryway without incurring any retaliation. The 4th year, they got twitchy about people walking nearby. The 5th year, they regularly chased people who passed within about 20 feet of their hive entrance. The colony died off entirely that winter. Far as I saw, it never swarmed, indicating they didn't produce any new queens.

We probably don't see this in domesticated colonies because modern beekeepers are diligent about replacing queens in a timely manner. But I asked an old-timer about it (who'd been in the bee business since the 1930s) and he said that was all perfectly normal for a colony with an old queen.

I'm not against the death penalty; I'm against making irreparable mistakes.

There's a way to prevent gung-ho justice: if judgment is later found to be in error, visit the same penalty on those who condemned. Tho I vaguely recall this principle comes from Sharia law, and if so it doesn't seem to limit behavior much in Real Life.
