Study: Pesticides Not Cause of Honey Bee Problems

An international team of scientists published a paper studying the possible causes of Colony Collapse Disorder (CCD) which as affected managed honey bee colonies in the U.S. The study was published on PLoS ONE, a journal published by the Public Library of Science. The article is available at: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0006481#top

The study compared the risk factors between hive populations afflicted by and not afflicted by CCD. The sutdy found that bees in CCD colonies had higher pathogen levels than control populations. The affected hives were also co-infected with a greater number of pathogens. The researchers suggest that an increased exposure to pathogens or a reduced resistance of bees toward pathogens could be a cause. The researchers, led by the Pennsylvania state apiarist Dennis vanEnglesdorp, suggest that CCD involved an interaction between pathogens and other stress factors.
