Objective 1: Determine biologically-based management programs using biological control agents and cultural controls. ¿ Sub-objective 1A: Determine the potential of Habrobracon hebetor as a natural control of field populations of navel orangeworm. ¿ Sub-objective 1B: Determine the feasibility of using a combination of sanitation and entomopathogenic nematodes for postharvest control of navel orangeworm in pistachios. ¿ Sub-objective 1C: Disrupt symbiotic aspects of California grey ants (CAGA) with mealybug pests on grape vines to allow biological control of the mealybugs. Objective 2: Develop behaviorally based management programs using pheromone trapping, mass trapping, and mating disruption. ¿ Sub-objective 2A: Develop attract and kill traps to control olive fruit fly in table olive orchards. ¿ Sub-objective 2B: Determine efficacy for navel orangeworm control using mass trapping of males with sex pheromone. ¿ Sub-objective 2C: Elucidate mechanisms of navel orangeworm mating disruption. Objective 3: Develop alternative physical treatments for fresh and durable commodities. ¿ Sub-objective 3A: Determine potential of combinations of high temperature and controlled atmosphere for control of codling moth in walnuts.
