Stinkbugs Seek Orchard When Shrubs Dry

Adult stinkbugs puncture fruit with their beaks to feed on the fruit flesh. Stinkbug damage in apples can occur beginning in mid-summer and accumulate through the harvest period when new adults move into the orchard from outside habitats.
Taiwan Protocol and Export Required Sampling
Wednesday Jul 15, 2026
Those expecting to export apples to Taiwan need to have their training updated every two years and use the sampling protocols negotiated with Taiwan. Three Orchard and Field Bin Sampling Protocol training sessions are scheduled for August.
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.
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.
