Bin Piles Are a Source of CM Off the Normal Model
Wednesday Jul 01, 2026
Bin piles placed in the orchard are often a source of codling moth. Larvae spin up in the bins in the fall and emerge when the bins are placed in the field. Because the bins in the center of a pile are insulated from temperature changes, adults emerge from bins at different times than predicted by the model.

How Does Codling Moth Mating Disruption Work?
Wednesday Jun 10, 2026
Mating disruption dispensers work by releasing synthetic pheromone which prevents or delays males from finding females, thus reducing the reproductive rate of the population. Now is the time to decide which dispensers to place in the orchard so you have enough time for ordering and to organize your work force.
What is DAS?
The Decision Aid System (DAS) is a collaborative project between WSU Extension, the WSU Agricultural Research Center, and partners in agricultural industries. The DAS is a web-based platform designed to transfer time-sensitive information to decision makers. We run insect, disease, disorder, and horticultural models to predict on-farm conditions in real time, and link these site-specific forecasts to appropriate management and pesticide guidelines.
