Prospection and Identification of natural’s enemies of Pterochloroides persicae Cholodovsky (Hemiptera, Aphididae) in Tunisia

Abstract

A study carried out from 2010 to 2014 documented the prospection and the identification of natural enemies associated with colonies of Pterochloroides persicae in cultivated Prunus sp at different sites in Tunisia. The predator’s records were principally the coccinellid Coccinella algerica Kovar, two syphids, Episyrphus balteatus and Metasyrphus corollae and one lacewing Chrysoperla carnea. C. algerica was observed from February to June and the highest number of adults and larva was registered on April in the three studied sites. Nevertheless, syrphid flies and lacewing were observed from April to June with numeric importance respectively in Chott Mariem and Jammel.
