Polyphagous Shothole Borer Susceptible Tree Variety Numbers Growing.

I've been accused of being alarmist about the potential of the Polyphagous Shothole Borer to be a destructive pest here, but it's been pretty alarming. A new paper by Dr. Akif Eskalen and several other researchers has come out detailing the growing number of hosts and trees affected by this pest doesn't do much help. Turns out of all the most planted ornamental trees here in Southern California, over 60% are attacked by the beetle in some way.
