Thanks to ongoing support from Quarantine Area (QA) residents, the Department of Primary Industries and Regional Development (DPIRD) is getting closer to eradicating Queensland fruit fly (Qfly) in Perth’s western suburbs.

The Spring Baiting program was successful in suppressing Qfly, with no detections for more than 100 days.

Our baiting program is now complete

We will continue to monitor some properties for remaining Qfly and to ensure that residents continue to comply with QA Notice requirements (see website for more details).

Residents will be contacted advising them of any updates to their visit schedule.

QA residents must continue to comply with QA Notice requirements (see website for more details).

Quarantine Area Notice Requirements

Sterile Insect Technique (SIT)

The Sterile Insect Technique (SIT) is now being used to mop up any remaining wild Qfly in the QA.

Sterile Qfly will be released on a weekly basis to mate with any residual wild Qfly, resulting in infertile eggs and no future hatchings of fruit fly larvae. The sterile flies are dyed with a fluorescent powder which glows under UV light for easy identification.

DPIRD will assess the effectiveness of the program by checking the traps in the Quarantine Area weekly and examining any adult Qfly found under a fluorescent microscope to determine if they are SIT or wild Qfly.

Why is eradicating Qfly so important?

WA’s commercial fruit and vegetable industries are valued at approximately $1.083 billion annually.

If Qfly were to become established in Western Australia it would cost $38 million per year to manage. It could also have a significant impact on the export of avocados, table grapes and strawberries.

An established population of Qfly would affect people’s ability to grow and enjoy fruiting plants in their gardens.

DPIRD thanks residents for their continued support to eradicate Qfly.
