of exotic oaks, Quercus spp.
in Victoria and Tasmania, Australia.
The parasitoid Aphelinus
flavus (Nees) was imported
from England and released in 1939.
The parasitoid began to be recovered shortly after, and as parasitism
increased in Tasmania, Wilson (1960) reported that the health of oak trees
gradually improved (also see Dahlsten & Hall 1999). REFERENCES: [Additional references may be found at: MELVYL
