The brown marmorated stink bug Halyomorpha halys (Heteroptera: Pentatomidae) is a harmful polyphagous species that recently became a key pest of hazelnut. Its rapid spread in different areas worldwide is causing yield losses. For this reason, several studies have focused on low-impact control strategies in an integrated pest management (IPM) framework. The reduction of pesticide use is the main goal of IPM, and for this the prediction of H. halys population development is an important partof setting up innovative strategies. Currently, projections are empirically based on data from field monitoring. In addition to the estimates being rough, monitoring takes time and resources and requires expert technicians. Mathematical models may support monitoring, more precisely predicting potential pest outbreaks. This study is the first part of a general ordinary differential equation (ODE) model describing insect pest populations in the case of H. halys. Accordingly, we analyzed the current literature on the species looking for quantitative biological data that support the model application.The resulting model has the potential for describing H. halys populations over time and through its life stages, considering the interaction between the species and the external environment, as well. Moreover, this feasibility analysis provided promising results for further field validation experiments. Information provided by the agent in SIGEVAKey Words
