as a Wild Field Host of (Hemiptera: Triozidae) and ' Liberibacter solanacearum'.

The potato/tomato psyllid, (Šulc), is among the most important pests of solanaceous crops as a vector of the pathogen ' Liberibacter solanacearum' (Lso). Lso-infected psyllids often arrive in crop fields from various wild species of Solanaceae and Convolvulaceae, especially those that provide early-season hosts for the vector. species are perennial plants within the family Solanaceae with often broad geographical distributions that overlap those of , yet the status of many species as hosts for or Lso remains unknown. Our objective was to determine whether wild species that occur in the potato-growing region of Galeana, Nuevo León, Mexico, host populations and whether they also are susceptible to Lso. Sampling was carried out in the potato-growing zone of Galeana, Nuevo León, Mexico, where unidentified spp. are common. In March to October 2021, a wild plant identified as was observed; eggs, nymphs, and adults of were observed on these plants throughout the growing season, and nymphs completed development on these plants under laboratory conditions. Lso also was detected in 22 of the 93 (23.7%) wild plants using conventional PCR, while 13.3% of adults that emerged from cuttings harbored the pathogen. This is the first report that is a host for and for Lso. These results suggest that is a likely source of Lso-infected psyllids colonizing solanaceous crops in northeastern Mexico. The importance of and other wild hosts on the population dynamics of the vector and pathogen should be investigated to assist in pest management decision-making.
