Research Project: Postharvest Cold-treatment of California Stone Fruit (Peaches, Plums, Nectarines and Apricots) for the Spotted Wing Drosophila, Drosophila Suzukii

Location: Commodity Protection and Quality Research

Project Number: 2034-43000-040-09-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Jan 1, 2014
End Date: Nov 15, 2015

The objective of this project is to conduct research that proves spotted wing drosophila (SWD) can be eliminated from trade channels of California stone fruit to New Zealand and Australia without the use of postharvest methyl bromide fumigation.

USDA-ARS will 1) identify the most cold-tolerant life-stage of SWD at treatment temperatures and durations relevant to stone fruit marketing (ca. 32-35 F), 2) enumerate the time required at the respective temperatures to control the most cold-tolerant life-stage of SWD , and 3) conduct confirmatory trials with > 30,000 specimens of the most cold-tolerant life-stage of SWD. USDA-ARS will then work with industry and USDA-APHIS to transfer results from these studies into commercial protocols and considerations as part of a systems-based strategy for California stone fruit access to New Zealand and Australia.
