Glad to hear they wont attack other trees. Has this hot dry summer been bet=
ter conditions for the larve survival. I have never had some many alders de=
foliated before. With so many beetles in the future will the defoliation be=
 worse next year.=0A=A0=0ARob=0A=0ATo free oneself of knowledge is to die, =
