Liberibacter Ca. Liberibacter asiaticus
Abstract
AbstractBACKGROUNDCitrus huanglongbing (HLB) is a devastating disease caused by Candidatus Liberibacter asiaticus (CLas) that affects the citrus industry. In nature, CLas relies primarily on Diaphorina citri Kuwayama as its vector for dissemination. After D. citri ingests CLas‐infected citrus, the pathogen infiltrates the insect's body, where it thrives, reproduces, and exerts regulatory control over the growth and metabolism of D. citri. Previous studies have shown that CLas alters the composit

Pentastiridius leporinus (Linnaeus, 1761) as a Vector of Phloem-Restricted Pathogens on Potatoes: ‘Candidatus Arsenophonus Phytopathogenicus’ and ‘Candidatus Phytoplasma Solani’

Abstract
In Germany, the phloem-sucking planthopper Pentastiridius leporinus (Hemiptera: Cixiidae) currently represents the epidemiological driver for the spread of the syndrome “Basses Richesses” in sugar beets, which results in a reduced sugar content and an economic loss for the farmers. This disease is associated with the γ-proteobacterium ‘Candidatus Arsenophonus phytopathogenicus’ and the Stolbur phytoplasma ‘Candidatus Phytoplasma solani’. Recently, P. leporinus was found in potato fields in Germa

First Report of the Association of the Psyllid Vector Bactericera trigonica (Hemiptera: Triozidae) with ‘Candidatus Liberibacter Solanacearum’ in Italy

Names
Liberibacter “Liberibacter solanacearum”
Abstract
Psyllids, members of the family Triozidae, represent a potential threat to the cultivation of solanaceous and apiaceous crops worldwide, mainly as vectors of the phloem-restricted bacterium ‘Candidatus Liberibacter solanacearum’ (Lso). The Lso haplotypes C, D and E are known to affect apiaceous crops, such as carrot and celery, in several European countries. In Italy, data on the incidence and natural spread of both Lso and psyllids have not been reported so far. In this study, the presence of t

First detection of ‘Candidatus Phytoplasma ulmi’ in Switzerland and in Orientus ishidae Matsumura, 1902

Names
Ca. Phytoplasma ulmi
Abstract
‘Candidatus Phytoplasma ulmi’ (Ca. P. ulmi) belongs to the ribosomal subgroup 16SrV-A and is associated with dieback, shoot proliferation and yellows disease on various Ulmus spp. Other plant species, such as Carpinus betulus and Prunus spp. have also been reported infected by the same pathogen. In 2021, in the frame of research activities focused on grapevine’s Flavescence dorée (FD), one specimen of Orientus ishidae - an East Palearctic leafhopper that was identified as an alternative vector o

An update on the presence of Leucomigus candidatus candidatus (Coleoptera, Curculionidae, Lixinae) in Romania

Abstract
This survey presents the first precise records of Leucomigus candidatus candidatus (Pallas, 1781) in Romania, confirming thus the presence of this species almost a century after its first and single record. Furthermore, ecology, habitat preference and distribution are discussed. We illustrate this taxon with high quality macro photographs, including the male genitalia with the everted and inflated endophallus. Comparative plates with similar-looking species are provided. New localities from Roma

Accumulation and Transmission of ‘Candidatus Liberibacter solanacearum’ Haplotypes by the Nymphs of Two Psyllid Vectors

“Liberibacter solanacearum”
Abstract
‘Candidatus Liberibacter solanacearum’ (Lso) is a plant pathogenic bacterium transmitted by psyllids that causes significant agricultural damage. Several Lso haplotypes have been reported. Among them, LsoA and LsoB are transmitted by the potato psyllid Bactericera cockerelli and infect solanaceous crops, and LsoD is transmitted by the carrot psyllid B. trigonica and infects apiaceous crops. Several studies evaluated the transmission of these haplotypes by adult psyllids. However, fewer data are
