Two invasive gall wasp species inflicted serious damage in Eucalyptus plantations on large areas. In Australia the six parasitoids of both gallers seem restricted to galls on Eucalyptus. The parasitoids, of the Eulophidae, Torymidae and Mymaridae, were released in Israel. The parasitoids led to the effective control results of O. maskelli and L. invasa. The success control was repeated in other countries mainly by natural spread of the parasitoids.
