Applying Management in PoPS

How does PoPS apply management in the model?

PoPS allows two types of management:

  1. Host removal (removes hosts from the cell)
  2. Pesticide application (converts infected hosts to resistant hosts for a given duration)
The efficacy of management application can range from 0 to 100%. The model also permits both management types to be applied simultaneously.

Below are examples of how PoPS applies management to a cell:

PoPS allows two types of management: host removal and pesticide application.

Management input as polygons is converted to raster management based on percent cell coverage. The “% removal” applied (a–e, above) is multiplied by the percent of the cell covered by the management (as shown below) to determine the overall percentage applied in a cell: for example, a cell with 50% management applied (a, above) but only 25% management coverage (below) would be calculated as having 12.5% of its hosts managed.
