[...] The decline of bees has been in the headlines for several years, and theories to explain their deaths abound. But perhaps there is not just one single cause. University of California San Diego professor of biology James Nieh studies foraging, communication and health of bees. "I would say it's a combination of four factors; pesticides, disease, parasites, and human mismanagement," says Nieh. Bees might be weakened by having a very low level of exposure to insecticides or fungicides, making them more susceptible if they are attacked by viruses or parasites.
