Research Project: Areawide Management of Spotted-wing Drosophila and Adoption of Sustainable Practices (NBF)

Location: Horticultural Crops Disease and Pest Management Research Unit

Project Number: 2072-22000-044-043-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2024
End Date: Aug 31, 2025

Objective:
Spotted-wing drosophila (SWD), Drosophila suzukii, a native insect of Asia, is now a serious world-wide invasive pest that attacks small fruits and cherries. Pesticides and other common management approaches for SWD have focused on within-crop management. Because SWD can develop on many wild and ornamental species, the surrounding landscape contributes to pest pressure, and therefore, areawide controls require closer examination. Our team of entomologists, commercial growers, and a crop consultants will work on an areawide management plan. The project will focus on large releases at our release site, and additional releases at other sites and the control site.

Approach:
The Areawide project implements sustainable tools based on: 1) evidence of efficacy, 2) likelihood of grower adoption, 3) availability of a commercial product, 4) practicality, and 5) economics. Areawide tools include parasitoid releases into the non-crop area, SWD modeling and monitoring to better time insecticide applications, use of non-toxic sprays or products that manipulate SWD behavior.
