UCCE's Dr. Beatriz Nobua-Behrmann will present "Using an Integrated Pest Management Approach to Shothole Borers" at the Long Beach Landscape Expo at noon on Oct. 14.
This workshop will be focused on the invasive shothole borers (ISHB; tiny invasive beetles that attack trees) and Fusarium Dieback (FD; the fungal disease vectored by the beetles). This insect-disease complex is responsible for the decline and death of hundreds of thousands of trees in Southern California.
The workshop will include information on the basic biology of the beetles and fungus and how to identify infested trees. I will also share the latest research findings on ISHB-FD management and distribution in Southern California. I'll review the best management practices and what to consider when making decisions regarding management of individual trees.
Learning Objectives:
1. Understand the basic biology of ISHB-FD and how it affects trees
2. Learn about management options for ISHB-FD and when to use each of them
3. Learn how to prevent the spread of this dangerous pest
