This study aimed to find out the Aphidoidea species feeding on different host plant in coastal area of Tunisia. Seventy six species of aphids distributed over 36 genera and 7 subfamilies are known so far in Chott Mariem. The aphids of the subfamily Aphidinae are the most abundant. During the present study 16 species under 7 genera and 31 species under 15 genera were newly reported respectively from Chott Mariem and Tunisia. From these determined species, Aulacorthum circumflexus Buckton, Aphis hederae Kaltenbach, Aphis illinoisensis Shimer, Aphis eugenia Van Der Goot, Aphis maculata (Aphidinae), Eulachnus agilis Kaltenbach, Eulachnus nigricola Pasek, Cinara ferresi Swain, Cinara palaestinensis Hille Ris Lambers, Cinara pinea Mordivilko, Cinara tujafilina Del Guercio, Cinara magrebicha Mimeur, Cinara maritima Dufour (Lachninae), Myzocallis sp., Siculaphis vittoriensis Quednau Barbagallo (Drepanosiphinae) and Greenidea ficicola Takahachi (Greenideinae) were previously recorded from the studied area, while the remaining of the identified species were new records in Tunisia. Aphids are associated with 136 host plant species.
