| Abstract: | "BACKGROUND: We assessed the economic impact of the invasive pest Drosophila suzukii (Matsumura) on the soft fruit industry (strawberries, raspberries, blackberries and blueberries) in Trentino, Northern Italy, using cost-benefit analysis. A conventional integrated pest management (IPM) based on insecticide, mass trapping and cultural measures is compared with an upgraded IPM strategy based on exclusion netting. Costs and benefits associated with the change between the two are estimated to evaluate the most profitable strategy from a societal point of view. The robustness of the results to uncertainty in parameter values is assessed through probabilistic sensitivity analysis. RESULTS: In a period of low pest pressure, the conventional IPM strategy would likely be more profitable than no management. However, with higher pest pressure levels, the upgraded IPM strategy would increasingly be more profitable than conventional IPM as pest damage levels increase. CONCLUSION: 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.
