Prevalence in Potato of ' Arsenophonus Phytopathogenicus' and ' Phytoplasma Solani' and Their Transmission via Adult .

The planthopper (Hempiptera: Cixiidae) is the main vector of two bacterial pathogens: the γ-proteobacterium ' Arsenophonus phytopathogenicus' and the stolbur phytoplasma ' Phytoplasma solani'. These pathogens cause the disease syndrome basses richesses (SBR) in sugar beet (), which reduces the yields and sugar content. In 2022, potato () fields were found to be colonized by and the transmission of Arsenophonus was confirmed, resulting in symptoms like wilting, yellow leaves, and rubbery tubers.

Effects of succession crops and soil tillage on suppressing the syndrome 'basses richesses' vector Pentastiridius leporinus in sugar beet.

Background: Pentastiridius leporinus (Hemiptera: Cixiidae) is the most important vector of syndrome 'basses richesses' (SBR), a new disease that leads to severe economic losses in sugar beet. In this study, different soil tillage methods (ploughing and cultivator) and crops (winter wheat, spring wheat, maize and bare soil) following SBR-infested sugar beet were tested as potential management options in field trials. In the laboratory, the survival and development of first and third instar nymphs on wheat and maize was studied to further assess their suitability as host plants.

Potato () as a New Host for (Hemiptera: Cixiidae) and Arsenophonus Phytopathogenicus.

is a planthopper (Hemiptera: Cixiidae) that vectors two phloem-restricted bacterial pathogens to sugar beet ( (L.)): the γ-proteobacterium Arsenophonus phytopathogenicus and the stolbur phytoplasma . These bacteria cause an economically important disease known as syndrome basses richesses (SBR), characterized by yellowing, deformed leaves and low beet yields.
