The distribution of introduced parasitoids of Phthorimaea operculella (Zeller) in Victoria is described. Apanteles subandinus Blanchard and Orgilus lepidus Muesebeck were most abundant, but Copidosoma koehleri Blanchard was also recorded from several sites. Detailed analysis of data obtained through regular monitoring revealed that, in an area free from insecticides, parasitoids were a major factor in controlling P. operculella. This result differs from previously published opinions on the effect of parasitoids, and is attributed to the analysis of data, in this study, on a generational basis. The effect of insectide applications on P. operculella and its parasitoids is discussed.
