Dominant cixiid vector and transmission of 'Candidatus Arsenophonus phytopathogenicus' and 'Candidatus Phytoplasma solani'-related strain 16SrXII-P in sugar beet in Austria.

ABSTRACT: The presence of fastidious phytopathogenic bacteria 'Candidatus Arsenophonus phytopathogenicus' and 'Candidatus Phytoplasma solani' challenges sugar beet cultivation in Austria. Reptalus artemisiae (Becker, 1865) (referred before as Reptalus quinquecostatus sensu Holzinger et al. 2003) is the principal vector of 'Ca. P. solani' to sugar beet in Serbia, while Pentastiridius leporinus is the primary vector of 'Ca. A. phytopathogenicus' in western Europe and can also transmit 'Ca. P. solani'. This study investigates the epidemiology of the associated diseases in Austrian sugar beet fields. An extensive survey in 2024 at 33 locations revealed significant spatial and temporal variability in cixiid populations, with R. artemisiae emerging as the predominant species.
