This project is planned in 3 compounding phases as indicated below with corresponding objectives and hypotheses. Phase 1, year 1. Perform host trials to demonstrate status in peach, plum, nectarine and apricot for spotted wing drosophila and designate categories of host preference (such as, stage of maturity, commercial export grade or physical condition of the fruits) in stone fruits. Phase 2, year 2. Design, refine and execute experiments that allow spotted wing drosophila population densities to be traced through chemical and physical processes that are consistent with Western US stone fruit production and distribution to Australian and New Zealand markets. Phase 3, year 3. Determine the mortality of spotted wing drosophila eggs, larvae, pupae and adults in infested stone fruit, as well as, the phytotoxicological impact that results from Vaporphos phosphine at 3-5 C and index relative to methyl bromide at 15.6 C.
