Managing Western Corn Rootworm In The Face Of Widespread Resistance To Bt

Learn about different management options by attending this webinar.

By now, you must have heard that corn growers in large portions of the Midwest have been battling populations of western corn rootworm that are resistant to some varieties of Bt corn.  More recently, growers in dairy-rich areas of Michigan and New York have encountered this problem.  Of course, this problem is serious and we do not want it to develop in Pennsylvania or the eastern corn regions.  Previously in this newsletter, I addressed the relevance of this issue for our region.

In light of these resistance issues, fellow entomologists from the Midwest are preparing to present a webinar titled “Corn rootworm management in the transgenic era” to address this issue. If you are working with continuous corn, you should participate to learn valuable unbiased information on rootworm management. The webinar is free and is scheduled for Feb. 20 to provide information on current rootworm management options.  The program will begin at 1 p.m. CT and conclude at 2:30 p.m.  This program is supported by a USDA-NIFA North Central IPM program grant.

Topics to be covered include:

  • Rootworm biology and behavior; Dr. Joe Spencer, Illinois Natural History Survey
  • Resistance evolution and IRM for rootworm; Dr. Aaron Gassmann, Iowa State University
  • Adult management options: Dr. Lance Meinke, University of Nebraska-Lincoln
  • Larval management options: Dr. Bob Wright, University of Nebraska-Lincoln
  • Decision tree for grower management options; Dr.  Ken Ostlie, University of Minnesota
