Elmer, H.S., Brawner, O.L., & Ewart, W.H. 1980 California red scale predator may create citricola control dilemma.. California Agriculture 34: 20-21.

Notes: Scales discussed include Coccus hesperidum, Aonidiella citrina, Icerya purchasi, Aonidiella aurantii and Coccus pseudomagnoliarum; if an effective parasite of C. magnoliarum had been established in the untreated test plot, this scale would then need a pesticide application that probably would eliminate the parasties; integrated pest management techniques recommended.
