Hundreds of beekeepers, researchers and vendors are gathering in Huntington, W. Va., today for the Heartland Apiculture Society's 7th annual bee conference. The buzz this year is the honeybee crisis. Since 2006, they have been disappearing en masse and the cause for the collapse remains unknown. Guest: Dennis van Engelsdorp, Pennsylvania's acting state beekeeper. He's delivering the keynote address at the Heartland Apiculture Society's 7th annual bee conference.
