The cosmopolitan genus Aphytis Howard comprises approximately 50 species of which 13 are known to occur in South Africa. This paper presents a survey of the species found in this country and of some other species imported from overseas as an aid to the biological control of certain citrus scale insect pests in South Africa. The paper also attemps to supply the need for up-to-date keys for the determination of the species encountered in orchards infested with diaspine scales. For this purpose comparatively few publications were available in the past. A fundamental study of the systematics of the genus Aphytis was made by Compere (1955) whose paper may still be regarded as a standard for future work.
