SWATopti is a joint project of the Julius Kühn Institute (JKI) and the Chamber of Agriculture Lower Saxony (LWK). The aim of the project is to develop a forecasting model for the cabbage fly, the carrot fly and the bean seed fly that is ready for use in practice. It should also enable the user to simulate the expected general risk of infestation and the expected development of infestation over time for specific fields. The model is to be used as a management tool both for cultivation planning and for crop management in the scheduling of control measures or the handling of net covers. The SWAT forecasting software serves as the basis. Its modules for cabbage fly and carrot fly are based on Individual-Based-Models (IBM) for the abundance and age structure of the population. The parameters of the moduls have to be checked and validated on the basis of new and existing data sets. In addition, a new module for the bean seed fly will be developed. At the end of the project, the management tool will be made available to growers as a web application. For the development of the models, it is necessary to collect biological data and to close knowledge gaps in the physiology, population dynamics and ecology of the target organisms. For this purpose, the cabbage fly and bean seed fly are to be reared in the laboratory. Developmental parameters are to be worked out under constant conditions. In addition, field trials will be conducted to collect monitoring data on the phenology of the target species and to observe spatial population dynamics on a local scale.
