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.

Leaf curl found on Myopurum plants in Ventura County

Leaf Curl on Myopurum tree shrub plant, disease, pest controlThere is a new pest attacking plants in Southern California. This pest is called a thrips. It has become a very serious problem to a common ornamental shrub in Ventura County. It is commonly used among highways and freeways. The thrips damages the plants leaves and causes spectacular and unsightly damage.

Myoporum Trees/Shrubs are the target

These trees are commonly used as privacy hedges. They are lined on hundreds of miles along California’s highways. They are a robust ever green tree that bears white (or near white) blossoms in winter to mid spring.It is a fast growing shrub or small tree which appears dome shaped at first.

The symptoms you see is a very tight leaf curl.

The pictures to the right show the leaf curl that occurs. This leaf curl, when left unchecked can quickly spread throughout the entire tree. This greatly diminishes the attractiveness of the tree/shrub. It detracts from the tree’s privacy hedge affect as well.

About the Thrips (the pests)

Thrips are sucking insects. They are similar this way to aphids, mealy bugs, whiteflies and scales. The biggest threat to ornamental plants are sucking insects, like the thrips. Thrips are very tiny, and hard to be seen by the naked eye. They can be seen squirming when you uncurl the leaves that they inhabit. Their entire life cycle is only 10 days. They lay eggs, that hatch into nymphs and quickly grow into maturity. They suck the life out of the plants.

There is an expectation that this new genus of thrips, called Klambothrips, will cause widespread damage along the 100’s of miles using the common Myoporum plant.
