Tomato potato psyllid (TPP)

tomato potato psyllidThe Department of Primary Industry and Resources (DPIR) is seeking volunteers to participate 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 (DPIRD 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.


Trapping is scheduled for two seasons each year between 2020 and 2022. A season lasts for four weeks.

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

If you have existing citrus plant(s) in your garden you will also be asked to trap for Asian citrus psyllis.  DPIR will provide you with an additional set of traps containing a specific lure for trapping this pest.

By participating and collecting data, you will be contributing to this valuable national research. You will also receive official notification as valid proof your property is free from TPP if you come up with a negative result at the time of trapping and a free tomato plant for each trapping period.

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

To volunteer to be part of the program complete an online registration form.
