“…In this regard, polyphagous species developing and feeding on dicotyledonous weeds, such as Philaenus spumarius, earlier confirmed as a vector of 'Ca. P. mali' (Hegab & El-Zohairy 1986); aphrodes macarovi, a new species close to 'Ca. P. solani' vector aphrodes bicincta (Tishechkin 1998); empoasca spp.…”

Bois noir (BN), caused by ‘Candidatus Phytoplasma solani’, is a serious disease of grapevines in Europe. During the 2010–2012 survey in Perná vineyard (South Moravia, Czech Republic) a total of 4854 insect individuals were collected and among these, 95 insect species belonging to Auchenorrhyncha (77 species), Heteroptera (12), and Psylloidea (62) were indentified. The nested polymerase chain reaction-restriction fragment length polymorphism analyses confirmed Hyalesthes obsoletus as the main BN vector with 43.8% of phytoplasma positive individuals on average. A significant role of Anaceratagallia ribauti (22.6% of phytoplasma positive specimens) should be taken into account based on its occurrence and incidence of infected individuals. Eleven insect species were identified as new carriers of ‘Ca. P. solani’ or suggested as potential BN vectors in this work.

“…In addition to psyllids, some other insects have been reported as vectors of 'Ca. P. mali', including the spittlebug Philaenus spumarius, the leafhopper Artianus interstitialis (Hegab & El-Zohairy, 1986) and possibly Fieberiella florii (Krczal et al, 1988).…”

“…Previous surveys showed a natural infection with ’ Ca . P. mali’ in field-caught individuals of Philaenus spumarius (Linnaeus) (Hemiptera: Aphrophoridae) [ 34 ], Artianus interstitialis (Germar) (Hemiptera: Cicadellidae) [ 34 ], Stictocephela bisonia Kopp and Yonk (Hemiptera: Membracidae) [ 35 ], Metcalfa pruinosa Say (Hemiptera: Flatidae) [ 36 ], and Fieberiella florii (Stål) (Hemiptera: Cicadellidae) [ 37 ]. The transmission capability of the latter has been shown by Tedeschi and Alma [ 38 ], but never been confirmed for the other four species.…”

Apple proliferation (AP) is one of the economically most important diseases in European apple cultivation. The disease is caused by the cell-wall-less bacterium ’ Candidatus Phytoplasma mali’, which is transmitted by Cacopsylla picta (Foerster) and Cacopsylla melanoneura (Foerster) (Hemiptera: Psylloidea). In South Tyrol (Italy), severe outbreaks were documented since the 1990s. Infestation rates of AP do not always correlate with the population densities of the confirmed vectors, implying the presence of other, so far unknown, hemipterian vectors. By elucidating the species community of Auchenorrhyncha (Insecta: Hemiptera) at a regional scale, more than 31,000 specimens were captured in South Tyrolean apple orchards. The occurrence of 95 species was confirmed, whereas fourteen species are new records for this territory. Based on the faunistical data, more than 3600 individuals out of 25 species were analyzed using quantitative PCR to assess the presence of AP phytoplasma. The pathogen was sporadically detected in some individuals of different species, for example in Stictocephala bisonia Kopp and Yonk (Hemiptera: Membracidae). However, the concentration of phytoplasma was much lower than in infected C. picta and C. melanoneura captured in the same region, confirming the role of the latter mentioned psyllids as the main insect vectors of AP- phytoplasma in South Tyrol.
