The past year has been a bad one for America's honeybees, with commercial beekeepers reporting hive losses of up to 50 percent. Some blame the mysterious

What Do Honey Bees Need & Why? (carbohydrates, proteins, vitamins, minerals, water, etc.)
Dr. Wallace Thurman coauthors the first comprehensive North American survey of the economic forces which drive pollination services.
The study, titled "The Economics of Honeybee Pollination Markets," appears in the most recent issue of The American Journal of Agricultural Economics. The appears paper here (full text may require a subscription or payment):
CALS Research, NCSU's insight:
Andrew Core of San Francisco State Univ. has discovered another possible contributor to honeybee Colony Collapse Disorder (CCD), which threatens crop pollination and food security: a tiny parasitic fly, Apocephalus borealis, which oviposits in the bee's abdomen where the eggs hatch and the larvae eventually kill the host bee. The parasitic fly usually attacks bumblebees; but Dr. Core has found it also reproduces in honeybees, causing them to become confused and wander from the hive at abnormal times, such during the night.
Bacteria in the guts of honeybees are highly resistant to the antibiotic tetracycline, probably as a result of decades of preventive antibiotic use in...
Yale University researchers find that routine oxytetracycline use to prevent foulbrood appears to have caused genetic adaptation in bacteria in the honeybee.
The resistant bacteria were not found in honey, however.

"Pollination is basic science, but the cost of it is getting more complicated.
"CALS economist, Dr. Walter Thurman, finds that rising honey prices, invasive mites and higher diesel fuel costs have increased the price of services performed by commercial beekeepers during the past 20 years.
"Dr. Thurman's is the first comprehensive study of North American pollination markets."
This means higher consumer prices for the approximately 75% of food crops which are bee-pollinated.
