California red scale, Aonidiella aurantii (Maskell) (Hemiptera: Diaspididae) is one of the main pests of citrus in Spain. Until now the control of this pest has been conducted exclusively with the use of insecticides. The release of parasitoids of the genus Aphytis (Hymenoptera: Aphelinidae) in combination with petroleum spray oils is a biorational control strategy that is successfully applied in other parts of the world. However, this strategy has not been tested in Spain. In this work, we investigated, first the Aphytis species to be released under the Spanish citrus conditions, and second, we conducted preliminary assays to test the efficacy of both, releases of Aphytis melinus DeBach and petroleum spray oils.
