Summary: The objectives of this project were: 1. Develop baseline toxicity bioassays for codling moth and leafroller of new insecticides under development. 2. Select populations of leafrollers (in the laboratory) to determine their inherent potential to develop resistance to selected insecticides. 3. Develop molecular markers to use as a tool for early detection of resistance development in leafrollers and codling moth. 4. Survey codling moth and leafroller populations using discriminating concentrations for key insecticides. 5. Characterize cross-resistance in leafrollers between old and new insecticides. 6. Evaluate new insecticides for control of codling moth and leafrollers in field tests.
