Detection by ELISA of predators of Prays oleae (Lepidoptera: Plutellidae) in a portuguese olive orchard. Acta Horticulturae. ISSN 0567-7572. 586, p. 831-8340567-7572http://hdl.handle.net/10198/856Over 900 predators were collected during two years from a Portuguese organic olive orchard, and tested in a serological bioassay for Prays oleae predation. The highest number of predators tested positive during the phyllophagous and antophagous generations of P. oleae. Ants were the most commonly found predators, followed by Coleoptera, Hemiptera and spiders.engP. oleaePredatorsELISAOlivejournal article
