Bee health: background and issues for congress renée johnson specialist in agricultural policy united states, the value of pollination by bees and other insects to us agricultural in the united states, honey bee colony losses due to bee pests, parasites, pathogens, and disease. Bees and other insects that pollinate plants in the united states have suffered in recent decades from mites, pesticides, pathogens, land development and habitat fragmentation nevertheless, production of insect-pollinated crops has mostly increased this century now, new research shows that insect. In fact, honeybees are not even a “natural” part of the ecosystem in the united states they were imported from europe during the 17th century for honey production and crop pollination, although some colonies now live in the wild.
Pollinators such as native bees and honey bees are quite valuable as they contribute to the successes of agriculture and industry in fact, the monetary value of honey bees alone as commercial pollinators in the united states is estimated at about $15 billion annually with them doing almost 80% of all crop pollination. Honeybees are are not native to the united states claim: mankind’s tampering with nature threatens the survival of the honeybee and the “balance of nature” reality: honeybees in the united states are not natural they are a non-native farmed species imported to provide honey production and pollination services.
Nappc partners have formed specialist task forces to address all the issues that face pollinators, and one such group is the nappc honey bee health task force the nappc honey bee task force has several functions, determining each year the recipients of honey bee health grants that have for the past four years supported research in honey bee genetics, pesticide exposure, nutrition and management. The plight of bees- environmental science and technology dennis vanengelsdorp, marina doris meixner a historical review of managed honey bee populations in europe and the united states and the factors that may affect them. United states, the value of pollination by bees and other insects to us agricultural production is estimated at $16 billion annually 1 most of this estimated value (about 75%) is attributable to honey bees.
Preliminary figures commissioned by the us department of agriculture (usda) show that 28% of bee colonies in the united states were lost over the 2015-16 winter more than half of surveyed. Declining bee populations pose a threat to global agriculture for much of the past 10 years, beekeepers, primarily in the united states and europe, have been reporting annual hive losses of 30 percent or higher, substantially more than is considered normal or sustainable given that the majority of the planet’s 100 most important.
An official website of the united states government ccd, there are very few if any dead bees near the hive piles of dead bees are an indication that the incident is not colony collapse disorder experience due to management practices such as transportation to multiple locations across the country for providing pollination services.
For much of the past 10 years, beekeepers, primarily in the united states and europe, have been reporting annual hive losses of 30 percent or higher, substantially more than is considered normal or sustainable.
Over this same period, the number of managed honeybee colonies in the united states has gradually declined, reaching a low in 2008 with 23 million colonies, with increases of roughly 200,000 new colonies each year in 2009 and 2010. Insect pollination is integral to food security in the united states honey bees enable the production of at least 90 commercially grown crops in north america globally, 87 of the leading 115 food crops evaluated are dependent on animal pollinators, contributing 35% of global food production. Colony collapse disorder is the phenomenon that occurs when the majority of worker bees in a colony disappear and leave behind a queen, plenty of food and a few nurse bees to care for the remaining immature bees and the queen.
