Climate change, emerging infectious diseases (EIDs) and food security create a dangerous nexus. Habitat interfaces, assumed to be efficient buffers, are being disrupted by human activities which in turn accelerate the movement of pathogens. EIDs threaten directly indirectly availability access nutritious food, affecting global health. In next 70 years, food-secure food-insecure countries will face driving increasingly unsustainable costs production, predicted exceed national gross domestic...

Phytoplasmas are a group of plant-pathogenic, cell-wall-less bacteria vectored primarily by leafhoppers (Hemiptera Cicadellidae), one the most diverse families insects. Despite importance documenting associations between phytoplasmas, their insect vectors, and plant hosts to prevent disease outbreaks, such knowledge is currently highly incomplete largely neglects diversity system in natural areas. Here, we used anchored hybrid enrichment (AHE) recover DNA five genes (rbcL, matK, ITS1, ITS2,...
Bois noir is an important grapevine yellows disease in Europe that can cause serious economic losses production. It caused by stolbur phytoplasma strains of the taxonomic group 16Sr-XII-A. Hyalesthes obsoletus Signoret (Hemiptera: Cixiidae) most vector bois Europe. This polyphagous planthopper assumed to mainly use stinging nettle [Urtica dioica L. (Urticaceae)] and field bindweed [Convolvulus arvensis (Convolvulaceae)] as its host plants. For a better understanding epidemiology Switzerland,...
Phytoplasmas are phloem-limited plant pathogenic bacteria in the class Mollicutes transmitted by sap-feeding insect vectors of Order Hemiptera. Vectors still have not yet been identified for about half 33 known phytoplasma groups and this has greatly hindered efforts to control spread diseases affecting important crops. Extensive gaps knowledge on actual disease epidemiology prevent our understanding basic underlying biological mechanisms that facilitate interactions between insects,...
Despite several decades' effort to detect and identify phytoplasmas (Mollicutes) using PCR Sanger sequencing focusing on diseased plants, knowledge of phytoplasma biodiversity vector associations remains highly incomplete. To improve protocols for documenting diversity ecology, we used DNA extracted from phloem-feeding insects compared traditional with a next-generation method, Anchored Hybrid Enrichment (AHE) detecting characterizing phytoplasmas. Among 22 180 leafhopper samples that...
In this study, binding between the immunodominant membrane protein Imp of 16SrV‐D phytoplasma associated with Flavescence dorée disease (FD‐Dp) and insect proteins vectors non‐vectors FD‐Dp was tested. Six Auchenorrhyncha species, from distantly related groups were selected: Scaphoideus titanus, Euscelidius variegatus, Macrosteles quadripunctulatus, Zyginidia pullula (Cicadomorpha), Ricania speculum Metcalfa pruinosa (Fulgoromorpha). The vector status each species retrieved literature or...
Abstract The association between insect herbivores and vascular plants represents one of the greatest success stories in terrestrial evolution. Specific mechanisms generating diversity remain poorly understood, but it has become increasingly clear that microbes play important roles mediating plant–insect interactions. Previous research on phytoplasmas (Acholeplasmatales: Acholeplasmataceae), a diverse group plant-pathogenic bacteria, their hemipteran vectors suggests this system provides new...

In several mountain regions Alps, vineyards a valid alternative to homogenisation has followed post‐cultural land abandonment agriculture intensification. Key unanswered questions remain...

Seventy‐seven specimens cixiid tested sucrose–TE (Tris–ethylenediaminetetraacetic acid) diet and 62 them survived less than 24 h. Polymerase chain reaction (PCR) assays performed insect bodies detected presence phytoplasma, with an infection rate 32.5%. Restriction fragment...

Abstract Species assemblages are the results of various processes, including dispersion and habitat filtering. Disentangling effects these different processes is challenging for statistical analysis, especially when biotic interactions should be considered. In this study, we used plants (producers) leafhoppers (phytophagous) as model organisms, investigated relative importance abiotic versus factors that shape community assemblages, infer on their by applying three‐step analysis. We applied...
Phytoplasmas are obligate transkingdom bacterial parasites that infect a variety of plant species and replicate in phloem-feeding insects the order Hemiptera, mainly leafhoppers (Cicadellidae). The insect capacity acquisition, transmission, survival, host range directly determines epidemiology phytoplasmas. However, due to difficulty sampling lack follow-up transmission trials, confirmed phytoplasma hosts still limited compared with identified hosts. Recently, quantitative polymerase chain...
