The objectives of this proposal are to gather a second year of data comparing fatty acid profiles of navel orangeworm and do follow-up husksplit insecticide trials emphasizing application timing as a variable.
1) Fatty acid profiles: Laboratory analyses will be conducted on navel orangeworm adults trapped in adjacent walnut and almond orchards in 2019 to confirm the finding that females are trapped in the crop in which they developed more often than males. 2) Husksplit insecticide trials: use treatment of walnuts on individual branches to determine the impact of spray timing on husksplit insecticide treatments identified as most effective in 2018.
