1a.Objectives (from AD-416):
Development of an effective lure for the reliable detection and control of the female navel orangeworm moth.
1b.Approach (from AD-416):
Using electrophysiological, behavioral, and field trapping studies this project will optimize and implement recently discovered, non-pheromonal lures for female navel orangeworm.
Electroantennographic (EAG) analyses were conducted on male and female navel orangeworm to identify volatiles from almond, pistachio, and associated fungal emissions. Results were carried forward to behavioral assays to identify suitable blends. New blends have been formulated based on individual EAG results and used for field trapping and behavioral studies. Differences between navel orangeworm responses to various treatments have been demonstrated.
University of California, Riverside Completed: A laboratory-based behavioral bioassay has been developed that shows significant differences between navel orangeworm responses to different treatments. Navel orangeworm responses to almond meal (current monitoring tool), other published treatments (commercially not as effective as almond meal) and treatments developed by ARS researchers have been measured. This project directly relates to Objective 3 of the parent project.
