Colony collapse disorder 8 years later: What we know now that we didn't know then

Entomological Society of America

A symposium on honey bee Colony Collapse Disorder (CCD) will be held Sunday November 15 from 8:00 AM to 12:00 noon at the Minneapolis Convention Center during the annual meeting of the Entomological Society of America (ESA). Honey bee experts from all over the U.S. will discuss factors that may contribute to CCD, such as Varroa mites, pesticide residues, pesticide formulations, honey bee habitat, and honey bee genetics.

"Eight years ago, in 2007, ESA held a symposium on CCD called 'Colony Collapse Disorder in Honey Bees: Insight Into Status, Potential Causes, and Preventive Measures,'" said Richard Levine, one of the co-organizers. "This year's symposium will feature many of the same speakers, and it will be interesting to hear what they've learned in the past eight years."

The presentations and speakers are:

  • "The ABC and XYZ of CCD" by May R. Berenbaum, University of Illinois at Urbana-Champaign

  • "Varroa: The monster in our midst" by Dennis vanEngelsdorp, University of Maryland; Kirsten Traynor, University of Maryland; Karen Rennich, University of Maryland; Robyn Rose, USDA-APHIS; Jeffrey Pettis, USDA-ARS; Eva Forsgren, Swedish University of Agricultural Sciences; Grace Kunkel, University of Maryland; Shayne Madella, University of Maryland; Jay Evans, USDA-ARS; Dawn L. Lopez, USDA-ARS

  • "Honey bee health and the pathosphere" by Jay Evans, USDA-ARS; Ryan Schwarz, USDA-ARS

  • "The economics of honey bee health" by Kathy Baylis, University of Illinois; Miriam Bixby, University of British Columbia; Guyu Ye, University of Illinois

  • "Pesticides in pollen: A national survey of bee bread residues" by Kirsten Traynor, University of Maryland; Dennis vanEngelsdorp, University of Maryland; Karen Rennich, University of Maryland; Robyn Rose, USDA-APHIS; Jeffrey Pettis, USDA-ARS

  • "Do pesticide co-formulants and adjuvants impact bee health?" by Chris Mullin, Pennsylvania State University; Julia Fine, Pennsylvania State University; Maryann Frazier, Pennsylvania State University; Ryan Reynolds, Pennsylvania State University

  • "A year in the life: Honey bees living near corn fields" by Christian Krupke, Purdue University; Jeffrey Holland, Purdue University; Elizabeth Long, Purdue University

  • "Forage and nutrition in agricultural lands for honey bee colonies in the northern Great Plains region of the US" by Matthew Smart, U.S. Geological Survey; Marla Spivak, University of Minnesota; Clint Otto, U.S. Geological Survey

  • "Collaboration for healthy bees, healthy people, healthy planet: The honey bee health coalition" by Todd Peterson, Winfield (a Land O'Lakes Company)

  • "Is there a genetic component to colony collapse disorder?" by David Tarpy, North Carolina State University

  • "Long live the queen: Factors affecting honey bee queen health" by Jeffrey Pettis, USDA-ARS

  • "Tech-transfer teams: Working for beekeepers" by Katie Lee, University of Minnesota; Marla Spivak, University of Minnesota

  • "Tech-transfer teams: Helping honey bee breeders" by Marla Spivak, University of Minnesota; Katie Lee, University of Minnesota

ESA's Annual Meeting will feature nearly 80 symposia and thousands of presentations during a four-day period. In addition to CCD, topics will include bed bug management, genetically modified crops (GMOs), forensic entomology, the health of honey bees and other pollinators, insecticide resistance, integrated pest management, neonicotinoids, invasive species, biological control, forestry, ecology, and much more.
