Metopolophium dirhodum in Northern Germany Ma Chunsen, H.-M. Poehling, and Christian Borgemeister Metopolophium dirhodum is one of the most important pests of cereals in Europe.
Simulation is a powerful method to estimate the population density.
Very few efforts have been devoted for developing simulation models for M. dirhodum . This cereal aphid is different from Sitobion avenae in feeding position, overwintering strategy, reaction to environmental conditions. Cereal aphid densities vary between different regions. A simulation model for S. avenae is not necessarily used to predict the population dynamics of M. dirhodum . It is necessary to develop a simulation model for M. dirhodum .
