Pine Tree Killer
I have several pine trees that died suddenly (2 months from green to brown). There is evidence of a boring insect (holes are 3 - 5 mm). They only appear to attack a single species but are affecting trees that are widely separated. What should I do? I don't want this to spread further, especially beyond my property.

Thanks David. I was cutting down a dead tree and found this (live) insect inside. I'm assuming this is what is responsible. Can you please tell me what it is? Thanks
