What is the problem?
Tomato potato psyllid (TPP, Bactericera cockerelli) TPP vectors Candidatus Liberibacter solanacearum (CLso) CLso is putative agent causing zebra chip disease in potato But tomato, capsicum, tamarillo, chili, eggplant are affected too Little is known about ecology of TPP and CLso related to their
non-crop host plants

What are we doing about it?

How will this research be delivered?
Articles in grower magazines (e.g. NZGrower, Potatoes Australia) Industry-organised field days Website Potatoes NZ and Foundation for Arable Research Presentations at industry conferences, symposia, forums Scientific publications
Most of this done in NZ, have to investigate opportunities in AU

Who will benefit from this research?
Growers (potato, tamarillo, outdoor tomato, capsicum, chili eggplant, tomato)
Plant primary industries NZ & AU Biosecurity decision makers / Surveillance / Pest Risk Assessment /
Diagnostics- PHA, SPHD, SNPHS
PBCRC Government (state, federal & Norfolk Island) Researchers US, NZ, AU
- CRC2002/2156, CRC2146, NZ Govt funded TPP/CLso programme

Future
TPP- Is attraction to plant visual or olfactory?- How far do psyllids disperse?- Movement between different plant hosts- Is a landscape ecology approach worth pursuing?
CLso- Does CLso titre in TPP and weed hosts increase during season?
Management- Should growers remove weed host plants or not?- How do we integrate this knowledge in regional pest management
plans?
