Abdelrahman, I. 1974a Growth, development and innate capacity for increase in Aphytis chrysomphali Mercet and A. melinus DeBach, parasites of California red scale, Aonidiella auarantii (Mask.), in relation to temperature.. Australian Journal of Zoology. Melbourne 22: 213-230.

Notes: The author concludes that A. chrysomphali would be more effective against A. aurantii in winter and A. melinus would be more effective in summer, and therefore complement each other.
