"Alfalfa aphids were monitored and aphid parasitism was determined in three crop-growing seasons (2007-2009) in commercial alfalfa fields (Pyrenees) , where an intensive arable crop rotation is practicised under no-tillage and an integrated pest management system. Acyrthosiphon pisum, Therioaphis trifolii and Aphis craccivora were the aphid species colonizing alfalfa fields. Thirteen Aphidiinae parasitoid and four Aphelinidae (Aphelinus) were recorded. Asociations between aphid species and Aphidiinae and Aphelinidae emphasized that individual aphid species also possess individual parasitoid complexes (guilds) which do not interfer with each other on alfalfa. Parasitoid species (listed) are classified as potential candidate species which could provide biological control of their respective aphids in alfalfa." . "[D79FF31BAD99]" . . "4" .
