Southern California has a new threat to Sycamore, Avocado, Coast Live Oak, Box Elder and Castor Bean that causes severe damage and eventually tree death.  The Euwallacea fornicatus, suggested common name is Polyphagous Shot Hole Borer (PSHB), an Ambrosia Beetle, is rapidly killing mature trees throughout Southern California and there’s no way to stop them other than prevention.  Once a tree has been infected, the chance of saving it is extremely small.

This beetle has probably come to the area from South East Asia, and possibly Africa.  It is causing extensive damage to avocado trees in Israel.

Trees that already host some form of fungus are ideal for beetle reproduction.  The mild damage is branch dieback, but can quickly transition to death.  They normally only spend a small amount of time on the outside of the tree before boring in and causing the real damage.
