SC - questions/kinda long, sorry

I believe you are speaking of an infestation of Phylloxera vitifoliae, the
grape louse, which occurred in the mid-19th Century.  American grapes are
resistant to P. vitifoliae, so cuttings from European species were grafted
to the roots of American species.  The vinyards were damaged, but the
species survived.
