Technical Abstract: Spotted wing drosophila (SWD), Drosophila suzukii, was first identified in central California in 2009 and now populates regions of key fruit production, as well as coastal regions surrounding Pacific port terminals. The discriminatory nature of D. suzukii oviposition needs to be established on undamaged ripe fruit across a range of potential hosts, which include strawberries, raspberries, cherries, blackberries, blueberries, and grapes. With insight into this critical piece of SWD biology lacking, implementation of effective pre- and post-harvest control measures has been obstructed. Here, we report a postharvest host suitability index for the SWD based on the integration of a series of bioassays: preferential flight response to fruit-derived olfactory cues, oviposition rates on fruit, and developmental success in fruit-based media.
