PEST ALERT

There is a brand new insect pest in southern California that you should be aware of. It was first discovered October 6, 2008 on a Tipuana tipu tree in Carlsbad, California in San Diego County. Soil and plant lab contacted Orange County for help identifying this new insect pest. The sample was sent toCDFA where it was identified as Q - r a t e d t i p u p s y l l i d (Pl a t y cor y p h z a sp.). This is the first record of the tipu psyllid in California.
