WASHINGTON (Reuters) - Honey bees, which play a key role in pollinating a wide variety of food crops, are in sharp decline in the United States, due to parasites, disease and pesticides, said a federal report released on Thursday.

Genetics and poor nutrition are also hurting the species, which help farmers produce crops worth some $20 billion to $30 billion a year.

Honey bee colonies have been dying and the number of colonies has more than halved since 1947, said the report by the Environmental Protection Agency and the Agriculture Department.

The decline raises doubt about whether honey bees can fulfill their crucial role in pollinating crops that play a role in about one-third of all food and beverages sold in the United States, the report said.

"Overall losses continue to be high and pose a serious threat to meeting the pollination service demands for several commercial crops," the report said.

Pollination demands have increased so much in recent years that California's almond crop alone requires 60 percent of all managed colonies devoted to pollination -- rather than honey or beeswax production.

The United States is not alone in facing this concern: The European Union moved on Monday to protect its own falling bee population by banning three of the world's most widely used pesticides for two years.

The Varroa mite, a parasite first found in the United States in 1987, is the single biggest cause of colony loss in the United States and other countries, the report said.

Another main concern is the effect of pesticides on bee colonies. [More]
