1. Implement an area-wide IPM program that will reduce navel orangeworm damage, aflatoxin contamination, and broad-spectrum insecticide use throughout the Central Valley. 2. Collect baseline data characterizing the experimental plots in terms of NOW population density, historic levels of damage, sanitation efficacy, and the cost of current practices. Compare the efficacy of current and proposed NOW management programs using cost/benefit analysis. 3. Identify key variables responsible for both consistent control and program failure and analyze the relative importance of these variables using epidemiological/epizootiological statistics. 4. Expand an existing damage prediction model for Nonpareil almond damage that is based on Kern County data, to the other growing regions in the Central Valley; and develop a damage prediction model for pollenizer varieties of almonds and validate the model in the different growing regions. 5. Determine the role played by NOW movement among multiple hosts on the efficacy of the new management practices demonstrated. 6. Create NOW damage databases using grower-provided data that can identify high-risk areas for each commodity within a county and utilize these databases to develop a better understanding of the distribution of both NOW infestation and aflatoxin contamination within and between counties. 7. Work with farm advisers and an advisory council to develop educational programs and training materials to instruct growers on the strategies demonstrated in the area-wide proposal.
