Here is an article about a citrus grower in Florida whose use of pesticides has killed massive numbers of honeybees: http://www.dailykos.com/story/2013/08/29/1234812/-Florida-citrus-grower-...
Here is a quote from the article:
"One of Florida's largest citrus growers has been fined after a state investigation found it illegally sprayed pesticide that caused the death of millions of honeybees.
"For the last seven years, the nation's beekeepers have been plagued by a malady known as colony collapse disorder, in which bees disappear from their hives. Pesticides have been blamed as one of the causes.
"The $1,500 state fine last week is believed to be the first time a Florida citrus grower was cited in connection with a bee kill.
"Ben Hill Griffin Inc., headquartered in Frostproof, is so entwined with Florida culture that the University of Florida's football staduim is named for its founder. The citrus operation is run by the family's fourth generation."
