For objectives 1 & 2, female-baited and oviposition traps will be used to compare abundance of navel orangeworm males and eggs, respectively, between the center and edges of walnut orchards with historically high damage, and also to compare these codling moth and navel orangeworm abundance with infestation by these pests in harvest samples. For objective 3, mating disruption for navel orangeworm will be applied to orchard with historically high damage. Impact of mating disruption will be assessed based on the ability of males to locate live females in traps, oviposition by females, and infestation at harvest by navel orangeworm.
