What's killing the honeybees in the almond orchards?

Pardon my sarcasm - but I am stunned with this news. They think they have found what's killing the bees that are shipped in to the central valley to pollinate the almond trees every year at this time. This REALLY took some major sleuthing - and years of effort - to figure out the farmers have been spraying insecticide on the trees before or during pollination), and it's KILLING BEES.
