Les pucerons des cultures protégées et leurs ennemis en Tunisie

Abstract

Aphids in the protected crops and their natural enemy in Tunisia. The importance of damage caused by aphids in protected crops, led us to carry out the inventory of aphids as well as the antagonists and to study the distribution of aphid population of all crops in Chott Mariem area. This study allowed to reveal the existence of 5 species whose Myzus persicae Sulz, Aphis fabae Scop, Aphis gossypii Glover, Macrosiphum euphorbiae Thomas and Macrosiphum rosae L.M. persicae and A. gossypii are the most fearful because they are polyphagous. As far as the auxiliary faun is concerned, we showed the presence of Aphidius matricariae Haliday, Aphidius rosae Haliday, Aphidius ervi Haliday, Praon volucre Haliday, Praon sp, Diaeretiella rapae M'Intosh, Trioxys angelicae Haliday, Lysiphlebus confusus Tremblay & Eady, Aphelinus sp, Aphelinus asychis Walker, Coccinella septempunctata L, Anisosticta novem decimpunctata L, Aphidoletes aphidimyza Rond, and Episyrphus balteatus De Geer whose A. matricariae, C. septempunctata and A. aphidimyza are the most abundant and the most active in the aphid population control of protected cultivation.
