Cost-benefit analysis of controlling the spotted wing drosophila (Drosophila suzukii (Matsumura)) spread and infestation of soft fruits in Trentino, Northern Italy.

For the problem considered in this study, insecticide-based management is expected to prove less and less profitable as rising pest pressure levels lead to an intensification of the insecticide applications. Conversely, exclusion netting, despite being more expensive, is expected to be much more profitable, in terms of both its effectiveness in reducing pest pressure and its lower societal impact. © 2017 Society of Chemical Industry.
