Figure 4.

Spatial distribution of season-long wild male codling moth (Cydia pomonella) catches in traps in three integrated fruit production orchards (A–C) that are part of a pilot sterile insect release program. 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 wild moths, and the blue circles indicate the number of moths caught in that trap across the codling moth season for each year. Asterisk indicates the first year of sterile insect releases in those orchards.
