A rapid method for the detection and quantification of the vector-borne bacterium 'Candidatus Liberibacter solanacearum' in the tomato potato psyllid, Bactericera cockerelli.

摘要

The tomato potato psyllid (TPP), Bactericera cockerelli (Sulc) (Hemiptera: Psyllidae), is a serious pest of solanaceous crops and is widespread in areas of the USA, Mexico, Central America, and New Zealand (NZ). The species vectors the unculturable phloem-limited bacterial pathogen ‘Candidatus Liberibacter solanacearum’ (Lso) which is accepted as the causal agent of economically important diseases in several crops including potato, tomato, capsicum, and tamarillo (Liefting et al., 2008, 2009; Munyaneza et al., 2008; Abad et al., 2009; Crosslin & Bester, 2009; Lin et al., 2009). Recently, Lso has been associated with disease in carrots affected by the psyllid Trioza apicalis Foerster in Finland, Sweden, Norway, and in carrots affected by psyllids in the genus Bactericera in mainland Spain and the Canary Islands (Alfaro-Fernandez et al., 2012a,b; Munyaneza et al., 2010, 2012a,b).
