Last fall,beekeepers from states with warm climates began to report a sudden loss of honey bees.Losses were reported in twentyfour states and spread to Canada.Today,some beekeepers say thirty percent to ninety percent of their honey bees are gone.Food price could go up as a result.And some beekeeping businesses have failed.
Many kinds of plants,trees and grasses need bees to pollinate them.Bees gather nectar from flowers during this process.The liquid gives them food and material to make honey.As the bees land on flowers,their bodies pick up and drop off particles of pollen(花粉).Most flowering plants need pollination to reproduce.
Honey bees can die during the winter.But few dead bees have been found this time.Instead,the bees seem to have disappeared.Experts call the condition “colony collapse disorder”.
Agriculture Department official Caird Rexroad said the colony collapse disorder threatens about fifteen billion dollars worth of the country's farm economy.Mr.Rexroad commented at a hearing of a House of Representatives agriculture subcommittee.
Mr.Rexroad said the cause of the sudden loss of bees was not clear.The number of honey bees had already fallen before the colony collapse disorder began.
Experts say the varroa mite is at least partly responsible for the earlier decrease in honey bees.The mite is a tiny creature that feeds on honey bees.It may play a part in colony collapse disorder by carrying bee viruses.Or the problem may be caused by other disease and weather conditions.
Diana CoxFoster of Pennsylvania State University is part of the scientific group.Ms.CoxFoster says the nation needs honey bees that can defend themselves better against disease and insects.The recent mapping of most of the honey bees' genes offers the hope of a stronger honey bee some day.
