[MAIPC] spotted knapweed in the east

[Hough-Goldstein, J A]

All,
I am working on adding spotted knapweed to the list of invasive plants in the Mid-Atlantic that have biocontrol insects available for release, but the vast majority of published work deals with infestations in western rangelands. The implication seems to be that it rarely becomes invasive in the east, but maybe that is changing.
Does anyone know of (1) infestations of knapweed in particular habitats in the east or (2) any states in the eastern US that have released biocontrol insects targeting this species?
Thanks,
Judy
