Specimens of the psyllid, Trioza anthrisci (Triozidae) collected from the United Kingdom and Sweden were positive for the phloem-limited proteobacterium ‘Candidatus Liberibacter solanacearum’ (Lso). Lso has only been reported in seed in the UK, and has not been reported in crop plants, weed plants or psyllids. This is the first report of Lso haplotype C in the UK and of Lso in T. anthrisci, a new potential vector.
