A rapidly mutating virus has leaped from plants to honeybees, where it is reproducing and contributing to the collapse of colonies vital to the multibillion-dollar agricultural industry, according to a new study.
Tobacco ringspot virus, a pollen-borne pathogen that causes blight in soy crops, was found during routine screening of commercial honeybees at a U.S. Department of Agriculture laboratory, where further study revealed the RNA virus was replicating inside its Apis mellifera hosts and spreading to mites that travel from bee to bee, according to the study published online Tuesday in the journal mBio.
The discovery is the first report of honeybees becoming infected by a pollen-born RNA virus that spread systematically through the bees and hives. Traces of the virus were detected in every part of the bee examined, except its eyes, according to the study.

The tobacco ringspot virus acts as a quasi-species, replicating in a way that creates ample mutations that subvert the hosts immune response. That phenomenon is believed to be the driving factor of recurring viral infections of avian and swine influenza and of the persistence of HIV, the study noted.

Activists have raised concern about a class of pesticides known as neonicotinoids, which have been banned in Europe. A study last year linked the pesticide class with suppressed immune response and increased reproduction of viruses in bees. Another study found 35 pesticides and fungicides, some at lethal levels, in the pollen collected from bees servicing major food crops in five states, including California. But that study found neonicotinoids only on pollen from a single apple orchard.

Everyone please take note. It is the USDA and EPA and scientists from both organizations doing the majority of work on this. You know, I wonder how corporate agriculture would feel if we decided to shrink the size of government by say, not funding this work?
