The Coffee Berry Borer (CBB) in Hawaii has become a major research inquiry because of its drastic impact on coffee production since its first sighting on the island a few years ago.
The Big Island of Hawaii can be considered pretty much a confined system, however, several microclimate environments are present and contribute to a very complex system. Spreading is primarily caused through human vectors (i.e. berry skin mulch and compost processing stations, nurseries), although spread does occur through flight and therefore is affected by microclimates.
This paper presents a python model using raster analysis to analyze the iterative aspects of CBB spread through movement by flight and existence of suitability surfaces, movement by hitchhiking into highly susceptible areas (where there are available Coffee trees), random movement through non-linear decay and the affected of microclimates and local winds.
