Vertical and temporal distribution of spotted-wing drosophila (Drosophila suzukii) and pollinators within cultivated raspberries.

Pesticides applied during twilight that ensure coverage in the bottom half of the crop, or if applied in the late afternoon cover the entire crop, should improve the pesticide efficacy. However, previous studies suggest that specific D. suzukii (e.g. sex, mating status, age) may exploit different areas in the crop at different times, and more work needs to be done to understand how these aspects before a specific management program can be recommended. © 2019 Society of Chemical Industry.
