See below; maybe not so terrible after all. The jury is still out

"Etymologists and scientists tested the predator beetles with other native species to see if there would be other effects, but it's impossible to know in a short time-frame. There are many examples of humans introducing one new species to curb the growth of another and it going wrong."

If "etymologists" are testing the beetle then I would be worried.

Jokes aside, Classic Biocontrol is not necessarily a bad idea.  Sure there are examples of bugs-gone-bad, like the Asian ladybeetle, but that was many moons ago and now the quarantine requirements and research protocols before any release of a biocontrol agent are most stringent.  There still could be mishaps, but we as a society have to decide, chemical pesticides or new critter that we may never know is there and could balance an invasive prey.

Examples of biocontrol insects that have themselves gone out of control are relatively few.

So to fight an invasive, we introduce another invasive?  I would like to read about these introduced species to control others which have not caused problems. Not trying to be a dick, actually curious

I've done some light reading;

This is of interest.

Muddy, this is a VA Tech paper; you work on this project?

I have to be honest, the only stories I have read about was biocontrol failures. I also was taught from a very rigid anti-introduction stance. After what I have read, I am open to hear more about this and any works you recommend.


Michael Toris

I may be swaying on this.....

Quite a bit of interesting research out there

Interesting

L. nigrinus larvae must have HWA to be successful. Wow.

I think anything they can do without serious risk needs to be done. It's really sad seeing all the hemlocks dying, it's changed the whole character of the Smokies. I've spent a good bit of time doing trunk injections of Imidacloprid to save a few hemlocks, but that's some nasty shit to handle.

I have no great appreciation for any introduced species and certainly no admiration for any introduced that has elevated to invasive status.  Like others I do enjoy the occasional Smith or SOHO brown and recently the ugly-assed carp, all introduced.  If granted a wish, I would return all the watersheds to pre-whitey times, no dams and no aliens.

Chemicals worry me more than critters.

Interesting article --- pesticides in the pollen collected by a species introduced to the U.S.

Perhaps we've gone too far.

It would have been something to see, wouldn't it?

I cannot imagine.

Would love to see a mature American Chestnut in bloom, and listen to the buzzing sounds of pollinators. Chestnuts bloomed after poplar, and before sourwood.  Now there is a gap due to its absence.

An Amercian Chestnut thread would interest me.  The most awesome tree in North America, imo.

X2, Ken.

Having a grandfather who logged them with draft horses back in the day, and seeing old evidence in the hills gives me the shivers.

What a tree.

Speaking of 'merican chestnut.
Found one trying to regrow this weekend.
