The goal of this research is to systematically demonstrate complete ACP mortality over the course of harvesting, packing, and shipping periods of fresh California citrus destined for Australia.
Phase 1 (year 1) Objective: Design, refine and execute experiments that allow ACP population densities to be traced through chemical and physical processes that are consistent with CA citrus production and distribution to Australian markets. Specifically, we will test the following hypotheses: a) Commercial harvesting, cleaning, and packing practices effectively remove or kill all ACP life stages. b) ACP life stages cannot survive a simulated shipping scenario at 3 - 6 C for greater than 14d, even with potential food sources present. c) ACP mortality outcomes in a) and b) above are not statistically affected by citrus fruit age, species, and variety. Phase 2 (year 2) Objective: Quantitatively monitor ACP population density and mortality as infested citrus fruit is harvested, cleaned, packed, and shipped to Australian ports (simulation). Specifically, we will test the following hypotheses: d) ACP population densities in the field have no statistical effect on mortalities observed in a-c above). e) ACP mortalities observed in a-d) above are consistent between packing houses and shipping companies involved in the export of CA citrus to Australia.
