Popis: In the lower Murray valley of Australia, the major insect pest of citrus, California red scaleAonidiella aurantii (Maskell), is controlled by a number of introduced hymenopterous parasites. Parasite introductions began in 1943, and continued until 1979. Eight species, especially in the Encyrtid genusAphytis, were introduced and mass released. The only species to become permanently established wereAphytis chrysomphali Mercet,Comperiella bifasciata (Howard),A. melinus DeBach, andProspaltella perniciosi (Tower).A. melinus, introduced in 1961, has become widely established throughout the region, is the dominant and most important parasite, and now appears to have completely displacedA. chrysomphali (1954) in all areas.C. bifasciata (1943) is also an important parasite and is distributed throughout the area.P. perniciosi (1970) is established on a few orchards near Mildura.
