Hi:
In nw Connecticut the emerald ash borer has not really hit us yet but it will. I am taking down the ash trees on my woodlot now and feeding them into the wood stove. Our hemlock trees in most of the state have been hit hard by the woolly adelgid. Once the woolly adelgid gets in a stand of hemlocks you are looking at 3 years and all the hemlocks in the stand are dead. The one insect that has a lot of people concerned is the asian longhorned beetle. This beetle really impacts maple trees and most other hardwoods. Fortunately, the asian longhorned beetle spreads slowly and so far, has been contained by cutting down every tree in an infected area, running them through a chipper and then taking the chips to a biofuel plant. This is what was done to most of the trees in the city of Worester, Mass.
