PesTwin: a biology-informed Digital Twin for enabling precision farming
This work addresses the challenge of reducing crop damage from invasive pests for farmers and agricultural stakeholders, representing an incremental advancement in precision farming tools.
The paper tackles the problem of forecasting insect infestations in agriculture by developing PesTwin, a digital twin simulation framework that integrates pest biodata, environmental data, and GIS data to model pest invasions in realistic spatial and temporal scenarios, applied to the invasive fruit fly Drosophila suzukii.
In a context of growing agricultural demand and new challenges related to food security and accessibility, boosting agricultural productivity is more important than ever. Reducing the damage caused by invasive insect species is a crucial lever to achieve this objective. In support of these challenges, and in line with the principles of precision agriculture and Integrated Pest Management (IPM), an innovative simulation framework is presented, aiming to become the digital twin of a pest invasion. Through a flexible rule-based approach of the Agent-Based Modeling (ABM) paradigm, the framework supports the fine-tuning of the main ecological interactions of the pest with its crop host and the environment. Forecasting insect infestation in realistic scenarios, considering both spatial and temporal dimensions, is made possible by integrating heterogeneous data sources: pest biodata collected in the laboratory, environmental data from weather stations, and GIS data of a real crop field. In this study, an application to the global pest of soft fruit, the invasive fruit fly Drosophila suzukii, also known as Spotted Wing Drosophila (SWD), is presented.
