PestFinder is a project funded by the European Commission in the framework of the Marie Skłodowska Curie Postdoctoral Fellowship actions 2022 (grant n. 101102281). The goal of PestFinder is to contribute to the ongoing “precision agriculture” revolution by developing model-based control strategies for pest control. We firstly aim to develop models and methodologies that can guide in an optimal way the agronomical decisions that impact pest control. To pursue this aim, we will develop and validate models able to capture both the spatial diffusion and the temporal evolution of insects in a plantation. The focus will be then shift on how to use these models for pest monitoring, and on the interplay between quality of the estimation and data collection, to develop optimal data collection policies. In the last part of the project, we will use the developed results to develop model-based optimal pest control policies.
