Imported Bees Not Source of Virus Associated with Colony Collapse Disorder

from UDSA
Research entomologists Yanping (Judy) Chen and Jay D. Evans, both with the ARS Bee Research Laboratory here, conducted a detailed genetic screening of several hundred honey bees that had been collected between 2002 and 2007 from colonies in Maryland, Pennsylvania, California and Israel.

"Our study shows that, without question, IAPV has been in this country since at least 2002," said Chen. "This work challenges the idea that IAPV is a recent introduction from Australia."
