Biosecurity alerts: Queensland fruit fly updates

The Department of Primary Industries and Regional Development (DPIRD) is currently responding to an outbreak of Queensland fruit fly (Qfly) in the Perth suburbs of Dalkeith, Claremont and Nedlands.

Qfly is exotic to Western Australia.

An eradication program is underway to help prevent the spread of this pest, which includes surveillance and baiting activities, and establishment of a Quarantine Area.

Residents can find out more about the eradication program and how they can assist below.

We are appealing to Dalkeith, Claremont and Nedlands residents and businesses to do the right thing to support our horticultural industries and protect their home-grown Qfly host fruit*.

Eradication will not be possible without your compliance with Qfly Quarantine Area Notice regulations and providing property access to carry out surveillance and control activities.

*Fruit means any host of Qfly, including some fruiting vegetables, as listed in the Quarantine Area Notice.

What do I need to know?

If you live in the Quarantine Area:

  1. You can’t take home-grown Qfly host fruit* out of the Quarantine Area, unless cooked, or frozen for 24 hours.
  2. Do not give away host fruit to people who live outside of the Quarantine Area.
  3. Don’t take host fruit to school or work if it is outside of the Quarantine Area.
  4. Strip all branches of host fruit before putting into your Council green waste bin or leaving out for verge collection. It is against your council’s regulations to put food scraps into your green waste bin.
  5. You need to treat home-grown Qfly host fruit (including peels and scraps) before putting it in your general bin (cooked, freeze, solarise). See disposal guidelines for clarification.
  6. Pick all ripe or ripening fruit from your trees and plants, and pick up fallen fruit from the ground, every three days.
  7. Some properties will require visits from DPIRD to carry out baiting. You will recieve a contact card if your property requires inspection.

By following these simple steps, we will remove all possibility of Qfly being able to breed and establish in WA.

How was Qfly detected?

Qfly was detected by DPIRD through its permanent grid of approximately 2000 surveillance lure traps located across the Perth metropolitan area.

A number of male Qfly were first detected in late March 2020 in Dalkeith, and additional Qfly lure traps were placed around detection points to determine the spread of the outbreak. Further male Qfly were subsequently detected in Claremont and Nedlands.

It is important to note there have been no Qfly detections in any commercial fruit or vegetable production areas within WA this season.

What types of fruit does Qfly affect?

Qfly is considered to be one of Australia's most serious fruit pests, with a wider host range than the endemic Medfly. Hosts of Qfly, which includes some fruiting vegetables, are listed in the Quarantine Area Notice.

The Qfly host list is extensive, including – but not limited to - backyard favourites such as citrus, bananas, stone fruit, olives, tomatoes, avocado, mango, passionfruit, tomato, capsicum and chillies.

What is the Qfly eradication program?

DPIRD’s Qfly eradication program includes baiting and surveillance activities, and the establishment of an Outbreak Zone, a Quarantine Area, and a Suspension Area. This eradication program is being managed in accordance with the national Code of Practice for Management of Queensland Fruit Fly 1996.

What is the Quarantine Area?

The Quarantine Area Notice published on 3 April 2020 declared a Quarantine Area over all of Dalkeith, and parts of Claremont and Nedlands (see map).

The Quarantine Area covers a 1.5km radius from where Qfly have been detected, and will be in place for at least 6 months.

If you live in the Quarantine Area, you cannot move Qfly host fruit out of the Quarantine Area unless cooked, frozen for 24 hours or solarised, and host fruit must be regularly and properly disposed of by the guidelines outlined in the Quarantine Area Notice (see next page).
