Bacterial Brood Disease Control: National Management Survey 2011-2012

Some beekeepers use antibiotics prophylactically or in response to brood deseases European foulbrood and American foulbrood, which are caused by bacteria. Survey questions allowed a comparison of winter mortality among those who indicated they applied an antibiotic (Terramycin and/or Tylosin (Tylan)), at least once, to a majority
of their colonies between April 2011 and March 2012. Beekeepers who treated with antibiotics did not report losing more or fewer colonies than those who did not report treating with antibiotics. A majority of responding beekeepers did not treat with antibiotics (product used 341 as compared to no antibiotics used 3,268). When separating the products Terramycin (286 respondents used) with Tylosin (71 respondents used), again there was no significant difference within groups that used or did not use the product. More respondents are needed to make confident interpretations of these data.

The Bee Informed Partnership is a collaboration of efforts across the country from some of the leading research labs and universities in agriculture and science to better understand honey bee declines in the United States. Supported by the United States Department of Agriculture and the National Institute of Food and Agriculture, we’re working with beekeepers to better understand how we can keep healthier bees. The key to our success is the true partnership we maintain across a wide range of disciplines including traditional honey bee science, economics, statistics, and medical research that makes all these tools available to this important research. And just as important as the tools are the people. We not only have the leading researchers in the honey bee industry, we also have advisory boards from the commercial beekeeping industries, almond and other commercial growers, as well as naturalists and conservationists from across the country.
