Abstract

Survey of potato aphids and their natural enemies in Tizi Ouzou Northern of Algeria during a year 2013, a total of 308 individual natural enemies comprised of 07 predatory species and 3 parasitoid species were collected and identified. The results showed the mean abundance of predators, especially ladybird's species and Adonia variegata (Goeze, 1777) is represented by 53.8%. Only some bugs were found and the aphid parasitoids were represented by three species Aphidius ervi(Haliday, 1833), Diaeretiella rapae (M'Intosh, 1855) and Praon volucre (Haliday, 1833).
