Queensland Fruit Fly Detected in Perth Suburbs, Urgent Biosecurity Response Underway
The Department of Primary Industries and Regional Development has confirmed the detection of the Queensland fruit fly, commonly known as Qfly, in the suburbs of South Perth and Como. This invasive pest, considered one of the world's worst fruit pests, was identified through surveillance traps deployed by the department to provide early warnings and activate eradication efforts in Western Australia.
Eradication Measures and Community Action
DPIRD officers are now conducting inspections of street trees and trees on residential and commercial properties in the affected areas. They will apply an organic bait designed to attract and kill the Qfly, which is not established in WA but is present in other parts of Australia. Chief plant biosecurity officer Vincent Lanoiselet announced that a quarantine area and measures will be declared to prevent the pest from spreading, with more information to be provided to impacted landholders.
Residents are urged to dispose of ripening and fallen fruit, as well as fruiting vegetables like tomato, chilli, and capsicum, by solarising them. This involves securing the fruit in a black plastic bag and leaving it in the sun before placing it in the general waste bin, not the food organics, garden organics bin. This method helps kill any potential Qfly maggots and supports the eradication campaign.
Identification and Reporting of the Pest
The Qfly is six to eight millimetres long, with distinctive features including a red-brownish torso, yellow patches, a dark brown abdomen, and clear wings. Dr. Lanoiselet emphasized the importance of community support, noting that DPIRD has successfully eradicated 10 previous outbreaks in Perth, including a recent infestation in Willagee and surrounding suburbs last year.
Community members are encouraged to look for and report suspect Qfly sightings, especially maggots in fruit. Reports can be made via the MyPestGuide Reporter app or DPIRD's Pest and Disease Information Service at padis@dpird.wa.gov.au. This collaborative effort is critical to preventing the establishment of this damaging pest in Western Australia.
