Webinar Description:
The invasive shot-hole borers (ISHB) include two species of ambrosia beetles (the polyphagous and Kuroshio shot-hole borers) that transmit a fungal disease called Fusarium dieback. This beetle-disease complex has been responsible for the decline death of thousands of trees in Southern California.
Susceptible tree species include box elder, willows, sycamores, cottonwoods, oaks, and many other common trees in urban landscapes and wildland environments. ISHBs have already caused extensive ecological and economical damage in Southern California, and can easily spread to other regions through infested firewood and green waste.
Trained arborists can help prevent the spread of this pest through early detection and management of local infestations. This presentation will show participants how to identify the symptoms of ISHB infestation, assess infestation severity and how to handle infested plant material to avoid spreading this dangerous pest.
Learning Objectives:
1. Understand the extent of the threat that ISHB poses to our urban trees.
2. Learn how to identify ISHB infestation signs.
3. Learn how to manage ISHB infestations in urban landscapes.
