Invasive tree pests can cause severe damage to the urban forest. Tree care professionals in Southern California have to routinely deal with the aftermath of invasive shothole borers and goldspotted oak borer infestations, just to name a couple. Lack of timely management results in tree decline and even tree death. Furthermore, infested trees tend to become public safety hazards due to falling limbs. Management of these pests can be challenging, especially considering that there is no one size fits all solution. Correct identification of the pest, and the use of an integrated pest management program that takes in consideration the needs and limitations of each location and client is key for successful management. In this seminar, you will learn how to identify signs and symptoms of invasive bark and ambrosia beetle infestations. We will review the available management options for each pest and when it is appropriate to use each of them.
1. Learn to identify some of the most damaging emerging tree pests in Southern California.
2. Learn what integrated pest management is and how it can be applied to manage emerging tree pests.
3. Use study cases to understand the pros and cons of different management decisions.
