From: Establishing criteria for the management of tephritid fruit fly outbreaks
Examples of a maximum potential fruit fly dispersal distance based on the detection of a single specimen (adult or juvenile). a, c Provide illustrative contour maps for trappable fly densities from the site of first emergence. b, d Provide maximum dispersal distances (red circles) from potential sites of emergence (blue circles) based on the location of the first fly detection. The black lines labelled “D” indicate the overall maximum dispersal (green circle)
