In order to introduce the Tachinid parasite, Compsilura concinnata from Canada, to assist the native parasites of the brown-tail moth, Euproctis terminalis Walk., which attacks pine trees in South Africa, it is necessary to breed up large numbers of the fly for liberation in the field. Compsilura has about 138 known hosts; it is a potential parasite of Euproctis, because the latter is closely related to the American Brown-tail moth, Nygmia phaeorrhoea Don., which it parasitizes in Canada and the United States of America. Due to the difficulty of handling and breeding Euproctis in the laboratory, it was decided to breed the parasite in some other host.
