In yesterdays news paper here in the U.K reports of a Cerambycidae (Anoplophora glabripennis, native to china) that has invaded the island. The forestry commision is worried that this species is going to kill the trees here. Is it too late to eradicate this beetle, or indeed, should we eradicate it? I personally am happy that this new species is here. peter Attachments:

They were supposedly in Illinois, but I think that they were eradicated by the cold winters. I haven't seen any since 2004.

I heard that jeff. I didn't think they would survive the seasons we have over here. our winters seem to be getting colder every year. But as i said, i'm happy that they are here. Obviously i don't want the trees to become diseased by them, but i'm sure there's enough trees in the uk to survive.

More government scaremongering. If it is not native, kill it!
Same thing as when someone finds a Gipsy moth larva here, they burn the whole hedgerow, even though people have tried to reintroduce it for decades without success!
I think they are edgy after the Harlequin Ladybird fiasco!

The fear with this is the damage to urban trees, which can cost cities millions in damage to remove dead trees along streets and liability if they don't. I seem to recall that they were hitting oaks and maples in the Chicago Region, and the cities impacted had to remove infested trees to reduce spread. It's pure economics... Is it cheaper to ignore the problem, or try and nip the problem in the bud. I think the elm disease cost Chicago many millions in tree removal in the 1980's - it was the tree of choice that the city used to line streets.

Municipalities seem to favor monoculture when it comes to landscaping. If a disease or pest comes along, it wipes out all the monocultured plant species. Here in Texas, live oak is a preferred landscaping tree. We actually have a deed restriction in our subdivision that we have to maintain two live oak trees in our front yards, otherwise the homeowner's association can take legal action against you!
