The density of BCA abundance in a given simulation run for each combination of biocontrol aggregation (0.01, 0.02, 0.04, 0.08, 0.16, 0.32) and patchiness (0.25, 0.50, 0.75) in a heterogeneous simulation area with a small grain size. For all simulations, the initial abundance for the BCA was 400, some of which may be discarded when they were in the patches favouring the pathogen. The dashed line indicates the median value
