QUOTED MATERIAL:

Saving the HONEYBEE. By: Cox-Foster, Diana, vanEngelsdorp, Dennis,
Scientific American, 00368733, Apr2009, Vol. 300, Issue 4

> broad-spectrum analysis, sensitive to insecticides, herbicides and fungicides, found more than 170 different chemicals. Most stored-pollen samples contained five or more different compounds, and some contained as many as 35. But although both the levels and the diversity of chemicals are of concern, none is likely to be the sole smoking gun behind CCD: healthy colonies sometimes have higher levels of some chemicals than colonies suffering from CCD.

> No neonicotinoids were found in the original samples. But these or other pesticides cannot yet be exonerated.

* Maybe not, but if the neo-nics were NOT found and all those others
were, they don't seem to be very near the top of the list.
