Introduction:
Phytoplasmas are phloem-limited plant pathogenic bacteria, therefore only phloem-feeding insects can potentially acquire and transmit them. All known phytoplasmas are transmitted by insects in the order Hemiptera. However, vector species are restricted to only a few families of the suborder Auchenorrhyncha: namely, Cercopidae, Cixiidae, Derbidae, Delphacidae, Cicadellidae and in the Sternorrhyncha, Psyllidae (Weintraub & Beanland, 2006). Within a family, some species are known to be phytoplasma vectors, while others are not. Transmission specificity defines the fact that only selected species can act as vectors of a pathogen (Bosco & D’Amelio, 2010). But even within the same species different populations, mostly geographically separated, may occur which are competent pathogen vectors in one area but not in another.
