The story of the Eucalyptus long-horned borer is an IPM success. This pest caused serious damage in the early 1990s, but has been brought under control by natural enemies imported from Australia. Susceptible Eucalyptus species lost resin, branches and ultimately their lives, as the borer larvae fed on and girdled the trees. Many blue gums (Eucalyptus globulus) in the Arboretum died, but many remain and now appear to be out of harm's way.
