The change in the Capability scores of the delimiting strategies on various host landscape types and when the Method Sensitivity was 0.5, and the IE duration of the pest spread was overestimated. The inspector-estimated (IE) spread distances were matched with the true value (a) and greatly underestimated (b) (450 m/yr and 350 m/gen). For each realization of the simulated epidemic, all delimiting strategies started from the same randomly selected symptomatic individual. Boxplots for the Random, Poisson and Voronoi landscapes were obtained from 500 iterations, while boxplots for the Extreme Poisson and Extreme Voronoi landscapes were obtained from 200 iterations. Mean values are indicated with a dark-red diamond. The performance of the In-to-Out (Linear) and Adaptive (Linear) strategies was not assessed on clustered host landscapes.
