World class Penn State research zeroes in on root causes for the honey bee crisis
Honey bees are vital to our existence because they pollinate the world’s fresh fruits and vegetables. But that national and global food supply is in jeopardy because honey bees have been dying by the millions. Researchers at Penn State are now zeroing in on the root causes of the "colony collapse" that is devastating the bee population.
Reporters Priscilla Balseca, Joyann Jeffrey and Tashima Mithell talk with the Penn State entomologists who have now learned that four common pesticides are the reason behind the massive killing of bee larvae.
