Figure 8.

Spatial distribution of sterile male codling moth (Cydia pomonella) recaptured following release in three apple orchards (A–C) for six years. Orchards B and C share a border and are presented as one polygon (see Figure 2). Red triangles indicate pheromone traps that did not catch any sterile moths, and the blue circles indicate the number of sterile moth recaptured across the codling moth season.
