Much of the U.S.production of dried fruits and tree nuts occurs in the central valley of California. To provide consumers with quality product, processors must control postharvest insect pests. My current research involves the development of non-chemical treatments to solve this issue. I am concerned primarily with physical treatments using temperature extremes or vacuum, but I am also interested in insect parasitoids as control agents. The target pests for most of this work include both field pests of postharvest significance and stored product pests.
