摘要：The Western Corn Rootworm (WCR) has become a major pest to maizein Austria in recent years. We model damage potentials of maize yieldlosses and crop management options for WCR control in Austria. Thecrop management options include maize restrictions in crop rotationsas well as insecticide applications. Our integrated modelling frameworksequentially links a crop rotation model, a bio-physical processmodel and a bottom-up land use optimization model and representsAustrian cropland at 1 km resolution. We identify several hot spots forhigh WCR damage potentials, which are related to regional maize yieldlevels and maize shares in crop rotations. The results show that the reductionof maize in crop rotations is more beneficial than insecticideapplications in many agricultural production areas.
