摘要：The Western Corn Rootworm (WCR) has become a major maize pest in Austria. We analyze whether maize restrictions in crop rotations constitute a cost-effective strategy for controlling WCR infestation in Styria under climate change. Hence, we have developed an integrated modelling framework by linking a statistical climate change model, a crop rotation model, the bio-physical process model EPIC, the bottom-up land use optimization model BiomAT, and a statistical WCR model at 1 km spatial resolution. Model results reveal that reduced maize shares in crop rotations result in lower net returns in most regions, but can reduce WCR infestation considerably. The presented analysis may inform the design of WCR policies and control strategies.
