Add Image Aonidiella aurantii or red scale is an armored scale insect and a major pest of citrus. It is designed to teach about the life cycle and habits of the California red scale, Aonidiella aurantii and natural enemies such as the wasp parasites Aphytis melinus and Comperiella bifasciata, that lay their eggs in or on it. Abstract. Aphytis melinus is an important parasite of several species of armored scales including California red scale, latania scale, San Jose scale, and oleander scale. Organophosphate-resistant and -susceptible populations responded similarly to spirotetramat, suggesting there is no cross-resistance between these insecticide classes. I also thank the Citriculture staff, Amparo, Carlos, Carmina and Vicente, as well Several other closely related (and difficult to distinguish) Aphytis species attack various armored scales in California.
