Abstract Candidatus Liberibacter solanacearum (Lso) is a phloem-limited, Gram-negative, unculturable bacterium that is primarily spread by psyllid insect vectors. It is considered very invasive due to its ability to be transported primarily in infective psyllids (Munyaneza et al., 2007a; 2010a,b; 2012a,b; Munyaneza, 2012; Alfaro-Fernandez et al., 2012a,b). It has been shown that Lso distribution in the Americas, New Zealand and Europe follows the distribution of its known psyllid vectors (Munyaneza, 2010; 2012).In New Zealand, where Lso was introduced along with Bactericera cockerelli, supposedly from Western USA in early 2000s, the bacterium had already spread to both North and South Island by the time it was first documented in 2006 (Gill, 2006). It is clear that introduction of the psyllid vectors of Lso into new regions is likely to result in the rapid spread of this bacterium. Lso and several of its vectors are already on several alert lists, including the EPPO A1 Regulated Quarantine Plant Pests.
