Eighteen years of tufted apple bud moth pheromone trap catch data and fruit injury data were analyzed with a simple linear regression to create a model to predict fruit injury from early season trap catch. This model was incorporated into a pay-off matrix along with parameters such as cost of treatment, effectiveness of treatment, loss of income from fruit injury, etc. Using this pay-off matrix, growers can select their desired level of risk and make treatment decisions based on early season trap catch.

Species 1: Lepidoptera Tortricidae Platynota idaeusalis (tufted apple bud moth)
Keywords: model, prediction
