Tomato potato psyllid (TPP)

tomato potato psyllid

The Department of Industry, Tourism and Trade (DITT) is participating in a program to trap Tomato potato psyllid (TPP) and Asian citrus psyllid plant pests.

TPP is an exotic plant pest that attacks a range of plants, including:

  • potato
  • tomato
  • eggplant
  • capsicum
  • chilli
  • tamarillo
  • sweet potato.

TPP provides a pathway for the bacteria, Candidatus Liberibacter solanacearum (CLSO), which cause Zebra chip disease and psyllid yellows.

In 2017 TPP was detected in Western Australia (WA). The Department of Primary Industries and Regional Development WA (DITTD WA), is leading a nation wide project to improve early detection and reporting of TPP across Australia.

Asian citrus psyllid is an exotic plant pest that attacks:

  • citrus plants
  • curry leaf trees
  • orange jasmin plants.

The Asian citrus psyllid plant pest has not been recorded in Australia previously but has been detected in nearby countries. The trapping program will provide important information on whether the pest remains absent from Australia.


A community trapping program is underway with trapping for two seasons each year between 2020 and 2022. A season lasts for four weeks.

Participants are asked to install the MyPestGuideTM Reporter app at the beginning of trapping period. Information captured through this app will be analysed by DITT and provided to DPIRD WA for capture in a national database. Participants receive TPP traps, a tomato plant and instructions for the trapping programs.

Participants with existing citrus plant(s) are also be asked to trap for Asian citrus psyllid. DITT will provide additional traps containing a specific lure for this pest.

Community participation contributes to valuable national research. Participants receive official notification to demonstrate that their property is free from TPP if their property has negative results at the time of trapping.

All information will contribute towards declaring the Territory free of TPP and CLSO.

Additional volunteers will be sought in 2021.
