- We developed a grid-based lattice model called Mosaic-Pest that simulates the spatio-temporal dynamics ofMeligethes aeneus, a major pest ofoilseed rape, and its parasitoid, Tersilochus heterocerus through a landscape that changes through time accord- ing to agricultural practices. The following agricultural practices were assumed to influence the tritrophic system and were included in the model: crop allocation in time and space, ploughing, and trap crop planting. To test the effect of agricultural practices on biological regulation across landscape configurations, we used a complete factorial design with the variables described below and ran long-term simulations using Mosaic- Pest. The model showed that crop rotation and the use of trap crop greatly affected pollen beetle densities and parasitism rates while ploughing had only a small effect. The use of Mosaic-Pest as a tool to select the combination of agricultural practices that best limit the pest population is discussed
