Mass culture of California red scale and its golden chalcid parasites

Stanley E. Flanders

Hilgardia, 1951, vol. 21, issue 1

Abstract: The golden chalcid, Aphytis chrysomphali (Mercet), has been parasitizing the California red scale, Aonidiella aurantii Mask., for more than fifty years in California citrus orchards. Planned use of this parasite, although seriously studied In 1942 and again in 1946, was not actually possible on a large scale until the completion of a culture method in the spring of 1950 at the Riverside Insectary of the Division of Biological Control. This method made possible the production in commercial quantities of the California golden chalcid as well as a species, Aphytis sp. “A,” brought from China in 1947.
