This presentation will cover basic information about bark beetles, wood borers, defoliators, and sap-sucking insects, highlighting major native and non-native pests (including emerald ash borer and Mediterranean oak borer). Attendees will learn about stressors that leave trees exposed to insect attack, how to diagnose the types of insects that may be causing damage and identify what insects are not of concern, and how to prevent or mitigate damage to trees.
