New research on honeybee illness

Washington Post – Ecologist Colin Henderson co-authored a study that may have identified the cause of the honeybee illness that has plagued U.S. bees since 2006. Henderson, 59, is an associate professor of biology at the University of Montana. He and colleagues there found a correlation between colony collapse disorder (CCD) and a lethal combination of a parasite and a virus. The study, on which Army scientists at the Edgewood Chemical Biological Center near Baltimore also collaborated, has been called groundbreaking (though also controversial because one of the study’s lead authors previously received funding from a maker of pesticides that some blame for CCD). The honeybee die-off strikes about 20 to 40 percent of commercial beekeepers in a good year, Henderson says, and up to 60 percent in a bad one. When it hits a beekeeping operation, it can take out up to 70 percent of its colonies. Read Article
