The Australian parasitoid Psyllaephagus pilosus has been successfully introduced into California, Britain, France and Eire for the biocontrol of eucalyptus psyllid Ctenarytaina eucalypti. At each introduction site the parasitoid has rapidly established and produced major sustained reductions in eucalyptus psyllid populations. It has also spread rapidly to colonize adjacent areas. This paper explains the background and rationale to the programmes, summarizes details of the introductions and describes the subsequent dissemination of the parasitoid. Emphasis is placed on the methods employed, the potential pitfalls and the economic benefits that accrue. The effectiveness of the parasitoid as a biocontrol agent is discussed, together with some avoidable problems that might limit its efficacy. The potential for extending the biocontrol programme for eucalyptus psyllid to other regions of the world is highlighted.
