Dry Beans – Insects
The following show the most common insect pests of dry beans. Insects of concern in dry beans include below-ground feeders, sap feeders, as well as defoliators. Crops should be scouted throughout the growing season to monitor for damage, and control measures only taken if economic thresholds are reached to help protect beneficial insects present in the field.
