"Scientists have struggled to find the trigger for so-called Colony Collapse Disorder (CCD) that has wiped out an estimated 10 million beehives, worth $2 billion, over the past six years. Suspects have included pesticides, disease-bearing parasites and poor nutrition. But in a first-of-its-kind study published today in the journal PLOS ONE, scientists at the University of Maryland and the US Department of Agriculture have identified a witch’s brew of pesticides and fungicides contaminating pollen that bees collect to feed their hives. Bee populations are so low in the US that it now takes 60% of the country’s surviving colonies just to pollinate one California crop, almonds, a market worth $4 billion." treehugger/natural-sciences/scientists-discover-another-cause-bee-deaths-and-its-really-bad-news.html
