Panis, A., Carrero, J.M., & Limon de la Oliva, F. 1977 Nota biológica sobre la entomofauna de los cítricos en España. [Biological note on the entomofauna of citrus trees in Spain.]. Anales, Instituto Nacional de Investigaciones Agronómicas, Series Protección Vegetal No. 7: 139-143.
Notes: As a preliminary to the establishment of integrated control on citrus, a survey was carried out of the natural enemies of arthropod pests of citrus already present in groves in the Spanish Provinces of Valencia and Castellon. The parasites attacking Parlatoria pergandii Comst. were Aphytis hispanicus (Merc.), Aspidiotiphagus citrinus (Craw) and Prospaltella inquirenda Silv.; it was preyed on by Scymnus sp. (Pullus sp.), S. frontalis (F.), Cybocephalus sp., Lestodiplosis aonidiellae Harris and Androdiplosis sp. The parasites of Saissetia oleae (Ol.) were Coccophagus lycimnia (Wlk.), C. scutellaris (Dalm.), Metaphycus flavus (How.), M. helvolus (Comp.) (which had been released in March 1976), M. lounsburyi (How.), Scutellista cyanea Motsch. and S. nigra Merc. The species observed preying on Saissetia oleae were Coniopteryx sp., Scymnus sp. and Chilocorus bipustulatus (L.).
