Murua, M.G., & Fidalgo, P. 2001 [Preliminary list of natural enemies of Saissetia oleae (Homoptera: Coccidae) in olive groves in the province of La Rioja, Argentina.]. Boletín de Sanidad Vegetal, Plagas 27(4): 447-454.

Notes: [Original title: Listado preliminar de los enemigos naturales de Saissetia oleae (Homoptera: Coccidae) en olivares de la provincia de La Rioja, Argentina.] Saissetia oleae is an important pest in Mendoza, San Juan and La Rioja provinces, Argentina. During 1964 and 1967, two parasitoids were introduced for its control: Metaphycus lounsburyi and M. helvolus. These species were recovered in very small percentages, and their establishment was not evaluated. An inventory was carried out of natural enemies in La Rioja to check if the biological control agents introduced in Mendoza were present. Predators found included Azya bioculata, Linepithema humile and Chrysopidae sp. The parasitoids present were Metaphycus lounsburyi, M. flavus, Coccophagus caridei, Lecaniobius utilis and the hyperparasitoids were Ablerus ciliatus, Marietta caridei [Coccophagus caridei] and Brasema sp.
