"Knowledge and tools to combat western bean cutworm: an emergent and adaptive pest in North American maize" symposium was held on 21 March 2018 at the 9th International Integrated Pest Managment Symposium in Baltimore, MD.
Symposium Goals:
- improve understanding of the IPM issues surrounding WBC
- increase collaborations among multistate research and extension communities by bringing together and sharing knowledge, skills, and tools to increase adoption of effective IPM practices for WBC
The symposium program included six invited presentations and a concurrent poster and extension materials session, and involved WBC researchers from across the United States, Canada, and Mexico. During the poster and extension materials sections, several participants were interviewed by Rosemary Hallberg, Communications Director at the Southern Region IPM Center in Raleigh, NC.

Introduction to the Handy Bt Trait Table
The Handy Bt Trait Table (authored by Chris DiFonzo of Michigan State University, Pat Porter of Texas A&M University, and Kelley Tilmon of The Ohio State University) lists the types of Bt traits present in all of the corn hybrids sold in the United States. The table includes the trade names of hybrids with Bt traits, Bt event, protein(s) expressed, herbicide traits, and target insect species.

Introduction to Scouting and Making Treatment Decisions for WBC
Scouting for WBC egg masses (composed of white, dome-shaped eggs) should begin when the first adults are caught. Control decisions should be made shortly after the moth flight peaks, which is usually in early to mid-July. Several resources are available to help you effectively scout for WBC egg masses and to make treatment decisions.

- Scouting and Making Treatment Decisions for WBC by Silvana Paula-Moraes at University of Florida
- EC 1585 - Western Bean Cutworm Speed Scouting Spreadsheet
- The Western Bean Cutworm Speed Scout App allows users to speed scout corn fields and determine whether WBC populations have reached the action threshold for treatment. The free app is available for iPhone, iPad, iPod Touch, and Android devices and can be downloaded from the Apple App Store or Google Play by searching for "western bean cutworm."
Introduction to the WBC NebGuide
This NebGuide from UN-L Extension addresses the life cycle, scouting, and treatment of WBC in corn and dry beans.
