Contribution to the study of the bioecology of the aphids in a coastal area of Tunisia.
Research carried out on the aphid populations observed at Chott Mariem - Akouda, Tunisia, on cultivated or spontaneous host-plants, helped to establish a list of the aphids in a coastal area of Tunisia (the Tunisian Sahel). The bioecology of the most agronomically important species was also determined. This study found fifty species belonging to four subfamilies (Aphidinae, Chaitophorinae, Pemphiginae and Lachninae) and twenty natural enemies, and defined the aphid-natural enemy-host plant associations as well as the biological cycles of the agriculturally important species Aphis craccivora, A. fabae, A. gossypii, Myzus persicae and Pterochloroides persicae. Tables showing the aphid species, natural enemies and host plants are presented along with tables showing the biological cycles of the agriculturally important species.
