Invasive Shot Hole Borers
Polyphagous Shot Hole Borer (PSHB) is an exotic ambrosia beetle that was first detected in 2003 in Southern California. It is currently found in L.A., Orange, San Bernardino, western Riverside, and San Diego Counties.
Pine Bark Beetles
There are numerous species of Ips and Dendroctonus, bark beetles, that infest conifers throughout North America. Adults tunnel through the bark, mate and lay eggs in the phloem (inner bark).
This condition, if allowed to progress, will cause slow growth, leaf loss, and eventually tree death. Chlorosis is often caused by deficiencies of the micro-elements iron and manganese, and is particularly prevalent in oak.
