As most beekeepers know, the Varroa mite continues to be the most serious threat to honey bee populations in the United States and most of the world. The Honey Bee Health Coalition has a great resource with a varroa guide, varroa decision-making tool and new best management practices for beekeepers.  Drafted under the direction of the University of Delaware Professor Dewey M. Caron, these resources draw on the expertise of a variety of industry leaders and provides comprehensive information on diagnosis and treatment options for this ubiquitous pest.
