2005 Annual Report 4d.Progress report. This report serves to document research conducted under a Specific Cooperative Agreement between Kansas State University and ARS. Additional details for this subordinate project may be found in the in-house parent project 6402-22000-035-00D entitled, “Resistance Monitoring and Resistance Management of Lepidopteran Species Infesting Bt Cotton.” Work was initiated in 2004 to gather baseline information that will be used for the development of monoclonal antibody-based kits to distinguish tobacco budworm larvae from bollwrom larvae. This agreement is not far enough along to report on at this time.
