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?
