Characterizing earwig damage to citrus fruits, and damage prevention using trunk barrier treatments

European earwigs are increasing in citrus orchards. Yet, information about earwig damage potential, monitoring, and management are lacking. Also, improvements are needed in control of other pests that climb the trunks, such as Fuller rose beetles, ants, slugs, and snails. This project will provide critical information on earwig monitoring, damage, and citrus species preferences. It will also develop effective targeted management options for earwigs and other pests that climb the trunk. By providing timely and scientifically valid information on monitoring and management for important citrus pests, this project will increase the marketability and sustainability of California citrus.
