Sahline, Ouardanine and Sousse on 2008.Therefore, these observations show anextension of the distribution range of G.ficicola in Tunisia giving anotherexample of biological invasion by anaphid in Tunisia, similar to the earlierinvasion with Pterochlorides persicaealso from Asia (11). G. ficicola livesmainly at the lower side of young leavesand on shoots of Ficus spp., but there areIndian records in other hosts. In this case,it was indicated (5) that this aphid can bemet on dicotyledonous trees and shrubsand lives mainly in shoots and youngfoliage of trees, particularly Fagaceae, butalso Moraceae, Betulaceae, Juglandaceaeand less commonly on members ofevolutionary more recent families such asMyrtaceae, Rosaceae and Rubiaceae (9).The presence of this pest causes enrolledleaves and recovered leaves and fruitswith honeydew on F. nitida. Thesedamages induced weakening of treesconsidered among the most widespread inthe urban zones and further studies aboutG. ficicola as a possible pest on figorchards in Tunisia are recommended.Two factors may explain theoccurrence of G. ficicola in Tunisia.Firstly, exotic and native Ficus speciesare widely planted as ornamental trees inparks or streets and this offers many hostplants to this aphid. Trades with Asiancountries have increased in the past twodecades increasing the probability oftransporting accidentally this aphid in oron goods from this region of the world.Fig. 1.

Première observation de Greenidea ficicola en Tunisie. TunisianJournal of Plant Protection 4: 107-110.Greenidea ficicola a été rencontré pour la première fois sur Ficus nitida en 2007 à la localité deSahline. Ensuite, il a été observé durant 2008 sur d’autres espèces de Ficus dans différentes régionscôtières du Sahel tunisien telles que Monastir, Sahline, Ourdanine et Sousse. Quelques aspectsmorphologiques et biologiques de ce puceron sont décrits dans le texte.Mots clés : Greenidea ficicola, Ficus nitida, Tunisie.______________________________________________________________________________Tunisian Journal of Plant Protection 109 Vol. 4, No. 1, 2009
