Les cicadiaires vecteurs potentiels de phytopathogènes en vignoble tunisien (Hemiptera : Cicadomorpha : Fulgoromorpha)

The leafhoppers potential vectors of phytopathogene agents in Tunesian vineyards (Hemiptera: Cicadomorpha: Fulguromorpha). To know Tunisian leafhopper fauna in vineyards, several collects have been realized during 2001 on grapevine and spontaneous plants in the main vineyard regions, i.e. Rafraf, Baddar, Mraissa, Belli, Gobba, and Bousalem. A total of 1109 specimens were identifi ed. Thirty species were identifi ed, 25 Cicadomorpha and 5 Fulgoromorpha. 82.58% of the leafhoppers recorded in Tunisia are reported either as being serious vectors of virus or phytoplasma or direct damaging cultures, while the 17.49% remaining do not have an important role.
