2007 Annual Report 1a.Objectives (from AD-416) Contribute to a scientific information framework for managing insect resistance to transgenic plants by evaluating and integrating insect resistance management models. This information can provide enhanced support to the concerned public in its deliberations about the use of transgenic plants. 1b.Approach (from AD-416) This effort will bring together modelers working in the area of insect resistance to assist stakeholders in sorting out the implications of insect resistance management models. It will identify important data needs for protection of transgenic crops and will assist in the development of modeling efforts that will benefit the science of resistance management in general and Bt resistance in particular. 3.Progress Report This report serves to document research conducted under a Specific Cooperative Agreement between ARS and North Carolina State University to conduct research related to an Interagency Agreement (60-3625-4-0574) with the Environmental Protection Agency (National Risk Management Research Lab, Cincinnati, OH) and USDA-ARS. Additional details of research can be found in the report for the parent CRIS #3625-22000-016-00D, Ecologically-Based Management of Insect Pests of Corn. The purpose of this agreement is to contribute to a scientific information framework for managing insect resistance to transgenic crops. The collaborator pioneered the use of spatially explicit landscapes in models of insect resistance management. Most of the current insect resistance management models are based on the techniques he developed. The collaborator serves in an advisory capacity to this project and the effort has benefited enormously from the guidance and recommendations. The collaborator participated in the initial modelers meeting and the evaluation of the verification guidelines developed for the project. The collaborator’s insights and suggestions for project direction have been very helpful. Project Monitoring This modeling project is monitored with frequent conference calls and numerous emails with modeling project coordinators and the EPA collaborator. Conference call dates: August 18, 2006 November 1, 2006 April 10, 2007 May 9, 2007 July 11, 2007 July 19, 2007
