Case study in data analysis: Variables related to codling moth abundance and the efficacy of the Okanagan Sterile Insect Release Program

The authors consider the effect of orchard attributes and landscape in a heterogeneous area on the efficacy of a control program for the codling moth in apple orchards in British Columbia. The context is first presented, along with a set of questions of importance to the Okanagan Valley Sterile Insect Release program. Two groups of analysts then address a number of these issues using methods for spatial‐temporal data including counts, proportions and Bernoulli variables. The models are then compared and the relevance of the results to this operational program is discussed.
