Biosecurity alert - Russian wheat aphid

Please note: This content may be out of date and is currently under review.

Reporting options

Report the absence or presence of suspect aphids or damage IMMEDIATELY.

It is preferrable to use reporting apps to make a report.

  • Download DAFWA’s MyPestGuide Reporter app to your smart phone, take a photo and follow the prompts on the device. The app can be used in areas that do not have mobile coverage, as it updates and sends when returned to coverage or wifi.
  • When using the MyPestGuide app to report absence of aphids or damage symptoms, type '0 aphids' and/or '0 damage' in the 'I found' text box.
  • Growers and agronomists may alternatively choose to make reports by downloading the PestFax Reporter app to their smart phone.
  • When using the PestFax app to report absence of aphids or damage symptoms, select 'aphid-other/unknown' as the 'problem', and 'none found' as the 'severity' of problem.
  • If you do not have a smart phone you can create a web report online.

You can also make a report to DAFWA’s Pest and Disease Information Service on freecall 1800 084 881.

Warning about sending plant material samples

Please note: Do not send samples to DAFWA for diagnostic verification unless asked to do so.

If you find aphids or damage symptoms, please take photos in the first instance and upload them using the reporting options above.

This is because there is a risk of spreading aphids to other areas if they are not transported in an appropriate manner.

If a sample is required DAFWA staff will respond to you directly. They will provide advice on how to move and send samples to minimise the risk of spread.

On-farm biosecurity is important

Russian wheat aphid is spread by the movement of plant material, vehicles, machinery, equipment, livestock and wind. Adhere to good paddock hygiene measures to ensure any risk of spreading the pest is minimised, similar to managing for rusts.

  • Avoid driving vehicles through crops; and wash down vehicles frequently.
  • Limit the movement of people and equipment near the suspect crop.
  • Wash hands, and brush down clothes and boots that have been in contact with each crop.
  • Do not openly move or transport affected plant material between properties unless sending samples to your local DAFWA office.

Go to the Farm Biosecurity website for more guidelines.

Quarantine restrictions

There are currently strict quarantine procedures in place for movement of material from other States into Western Australia.

However, in light of this recent detection DAFWA has reviewed these measures and has strengthened requirements around imports of Poaceae nursery stock and Poaceae cut flowers/foliage from South Australia, which are also hosts of Russian wheat aphid.

This includes refinements of the existing chemical treatment for Poaceae nursery stock and increased inspection of Poaceae cut flowers/foliage. The volume of Poaceae cut flowers/foliage coming into WA is small.

In relation to the movement of machinery into WA, a new restriction requiring a statutory declaration has been introduced. For more information download the 'RWA Machinery Restriction Notification' from this page.

Existing stringent requirements in relation to the movement of hay and straw, and livestock have been reviewed and remain in place.
