Ya,,and they could have saved/save trees from insect infestation with it. Think the Dutch Elm, Birch Leaf Miner, Emerald Ash Borer, Gypsy moth, Bud Worm, etc, etc.
BTW, the Asian Long horned beetle is one that will devistate all broad leaf trees nationwide if left to get loose. That is..Oaks, Maples, Aspens, Popplars, Ashes, etc.
I have experience with the Emerald Ash Borer. Another Chinese gift that keeps on giving. All the Ash trees on my property have died. Nice tree, strong wood. That's what they make baseball bats out of. Had my large elm tree die about 15 years ago from Dutch Elm Disease. All of these diseases were introduced from foreign countries.
