“…Phytoplasmas are known to be responsible for several hundreds of plant diseases worldwide (Firrao et al 2005). The leafhopper J. olitoria is a potential vector of a phytoplasma associated with the North American Grapevine Yellows, a lethal disease of grapevines in the USA (Lenzi et al 2019). Similarly, it has been demonstrated in Italy that the Oriental species O. ishidae is a vector of the phytoplasma associated with the Flavescence Dorée, which is one of the most serious diseases affecting European vineyards (Lessio et al 2016 (Kusunoki et al 2002;Hao et al 2015).…”

During a one-year survey of the Auchenorrhyncha fauna in a maquis habitat of the Ajaccio region (Corsica), 37 species were listed including 3 alien species recorded in Europe in the last decades. The standard 658 bp mitochondrial COI barcode was obtained for 32 species, including 14 species never previously barcoded. Neighbor-Joining analyses confirmed the monophyly for all of them. However, comparisons with available sequences from the mainland Europe showed that 4 species presented a significant intraspecific divergence (>3%) whereas a reduced interspecific divergence was found for another set of species.Complementary studies are therefore necessary to better assess their taxonomic levels. Three species -Euscelis lineolata (Cicadellidae), Philaenus spumarius (Aphrophoridae) and Latilica maculipes (Issidae) -account for up to 74.3% of the total insects collected. Although phylogenetic and taxonomic interpretations using restricted sampling and COI sequences alone are not robust, the proportion of new sequences highlight the global lack of knowledge about the Auchenorrhyncha as a whole and the potentially presence of cryptic taxa in different clades. 2 Résumé. Diversité et variations temporelles de la faune Auchenorrhynque dans la région Ajacienne (Corse). Un suivi de la faune Auchenorrhynque dans un maquis de la région d'Ajaccio (Corse) effectué durant une année a permis l'enregistrement de 37 espèces, incluant 3 espèces introduites en Europe ces dernières décennies. Le fragment standard de 658 pb du gene mitochondrial COI utilisé pour le barcoding a été obtenu pour 32 espèces, parmi lesquelles 14 ont été nouvellement séquencées. La monophylie de chacune des espèces a été confirmée par les analyses en Neighbor-Joining. Dans le cas de 4 espèces, les séquences obtenues pour les spécimens de Corse présentent une divergence intraspécifique significative (>3%) par rapport aux séquences de spécimens d'Europe continentale; au contraire, une faible divergence interspécifique a été mise en évidence pour un autre groupe d'espèces. Des études complémentaires sont cependant nécessaires afin de clarifier le statut taxonomique de chacune de ces entités. Trois espèces -Euscelis lineolata (Cicadellidae), Philaenus spumarius (Aphrophoridae) et Latilica maculipes (Issidae)représentent à elles-seules 74.3% des insectes collectés. Bien que les interprétations phylogénétiques et taxonomiques basées sur un échantillonage limité et sur un unique gène mitochondrial ne sont pas robustes, la proportion de séquences nouvelles et la présence d'entités génétiques divergentes mettent en évidence le manque global de connaissances concernant les Auchenorrhynques.

“…Field surveys have revealed the diversity of leafhoppers associated with berries and grapevines in Canada and the United States, where they identify potential vectors and phytoplasma groups associated (e.g., Olivier et al 2014, Saguez et al 2014, Arocha-Rosete et al 2019, Lenzi et al 2019). Three studies contributed to the knowledge of leafhopper abundance and diversity in berries and grapevines: (i) Chandler and Hamilton (2017) created a checklist of leafhopper species in New Hampshire (USA), reporting 605 species, including 38 invasive; (ii) Saguez et al (2014) determined the diversity of leafhoppers in 80 commercial vineyards in British Columbia, Ontario, and Quebec, identifying 110 species; and (iii) Plante et al (2023) identified 118 leafhopper species in strawberry fields distributed in the province of Québec from 2021 to 2022.…”

Climate change has facilitated the introduction, establishment, and movement of invasive species in northern regions, enabling the colonization of previously unsuitable areas. While the responses of insects to these changes have been increasingly studied, our understanding of how such alterations impact trophic interactions still requires further research to make reliable predictions about the spread of diseases in a warming world. Phytoplasmas, a group of obligate parasitic unculturable Mollicutes, primarily rely on leafhoppers (Hemiptera: Cicadellidae) for transmission, spread, and survival. Phytoplasmas are associated with over 600 diseases affecting more than 1,000 plant species, including berries, grapevines, and other small fruits. In North America, diseases such as grapevine yellows, blueberry stunt, and strawberry green petal diseases have been linked to phytoplasma strains transmitted by known leafhopper species. However, the number of phytoplasma diseases has significantly increased in North America over the past decade, suggesting the presence of unidentified vectors or an abundance of leafhopper vectors. This short review provides an overview of the current knowledge on leafhoppers as vectors of phytoplasmas to berries, focusing on the last decade’s research in Canada. This paper also explores the potential implications of climate change on this pathosystem, including the anticipated range expansion of leafhopper species, changes in phytoplasma acquisition and transmission, and the risk of new leafhopper-transmitted plant-pathogen introductions through the arrival of new leafhopper species.

Field surveys were conducted in wine and table grape vineyards from June to October 2020 in 13 locations belonging to five governorates in North and South Jordan. Typical grapevine yellows symptoms, including leaf reddening/yellowing and rolling were observed on 10% to 55% of vines. Nested PCR‐based amplification of the 16S rRNA gene detected phytoplasmas in 22% and 15.7% of the analysed symptomatic wine and table grape cultivar plants, respectively. Amplicon nucleotide sequence analyses identified the detected phytoplasmas as “Candidatus Phytoplasma solani” (taxonomic subgroup 16SrXII‐A), “Ca. P. omanense” (16SrXXIX‐A and ‐B), “Ca. P. aurantifolia” (16SrII‐C) and “Ca. P. asteris” (16SrI‐R) in 72.4%, 17.2%, 6.9% and 3.4% of infected plants, respectively. Such phytoplasmas were found differentially distributed in wine and table grape cultivar vineyards surveyed. Further investigation identified “Ca. P. solani” in the putative insect vectors Orosius cellulosus (first report in Jordan), Euscelidius mundus, Laodelphax striatellus, and Circulifer sp., and in bindweed; “Ca. P. aurantifolia” in the insect O. cellulosus and in bindweed; “Ca. P. omanense” in the insect Psammotettix striatus; and “Ca. P. asteris” in the insects Arboridia adanae, Cicadulina bipunctata, Circulifer sp., L. striatellus, Hyalesthes obsoletus, and P. striatus. Based on this preliminary data, ecological cycles of such phytoplasmas are discussed. Results suggest that the diversity and ecology of grapevine yellows phytoplasmas in Jordan are more complex than previously known, leading to a potential risk of disease outbreaks.
