Re: iris borer, Iris tectorum

Betty, 

That probably should have been TB's.  That means Tall Bearded Irises.

What does TBS stand for?

I've heard that too and also interested about the line. TBS grow with less enthusiasm as you go deeper in the hot & humid Southeast. At some point people stop growing them at all, such as Florida and coastal areas along the gulf. Less TBS might explain a failure of borers to establish range?

Is there a North/South line also?  It seems  the people who have them are not in the deep South or Southwest.

The iris borer does indeed exist west of the Mississippi River.  It is also found west of the Missouri River.  I am in Lincoln, Nebraska (southeast Nebraska) and the borer is very  much alive and thriving here.  It does disappear west of us in central Nebraska.  It does not exist in western Nebraska, and does not get to the Rockies.  The Mississippi forms the border between Illinois and Iowa, and Nebraska is a few hundred miles west of the Mississippi.

Can tbose of you who responded to this post, please indicate where in the US you are growing irises?  I have heard that iris borers do not exist west of the Mississippi.  Can any of you let me know if it has crossed the Mississippi?

Does anyone know if Iris tectorum is susceptible to iris borer? And if
so, like to what degree compared to beardeds?

Thanks,
