Information on QFF management
Market access requirements
Consignment into and within Victoria (outside the Greater Sunraysia Pest Free Area)
Queensland fruit fly (QFF) host produce consigned into and within Victoria no longer requires certification and treatment – this excludes consignments entering the Greater Sunraysia Pest Free Area (PFA). However, it will remain an offence to sell infested produce unless done so in accordance with an approved protocol.
QFF host produce consigned into the Greater Sunraysia PFA must be certified under a Plant Health Assurance Certificate (PHAC) issued in accordance with an Interstate Certification Assurance (ICA) accreditation, or a Plant Health Certificate (PHC) issued by a DEPI inspector. QFF host produce originating from outbreak areas within the Greater Sunraysia PFA must also meet this requirement.
Certified produce received in Victoria that is reconsigned to the Greater Sunraysia PFA must be done so in accordance with Department of Economic Development, Jobs, Transport and Resources (DEDJTR) instructions, to maintain security against QFF infestation. Contact your local Plant Standards Officer on 136 186 for instructions.
Consignment from Victoria
Consignments to non-QFF sensitive markets
QFF host produce can be consigned from Victoria to non-QFF sensitive markets (i.e. New South Wales, Queensland and Northern Territory as well as the Sydney and Brisbane wholesale markets) without certification and treatment. This includes consignments to the Melbourne Markets.
Consignments to QFF sensitive markets (including Greater Sunraysia PFA)
Producers sending QFF host produce to QFF sensitive markets are advised to contact their local Plant Standards Officer on 136 186.
For accreditation options businesses are advised to visit the interstate certification assurance website, http://domesticquarantine.org.au/ica-database
Enquiries regarding international host product movement must be directed to the Department of Agriculture website, www.agriculture.gov.au
It is the responsibility of the consigning business to ensure compliance with all applicable quarantine entry requirements and that product consigned is free of QFF infestation.
Movement of infested produce
Under section 18 of the Plant Biosecurity Act 2010 (the Act), it is an offence to sell QFF infested produce. Any business found operating contrary to the Act may be prosecuted.
Penalties apply to businesses found not complying with legislative requirements including the return, treatment or destruction of produce at the owner's expense.
QFF management methods for producers
Practice good on-farm hygiene
Collect and destroy any rotting, overripe or unwanted host produce, whether it is on the ground or still on the tree, as this can become a breeding ground for QFF.
Intact fruit may appear unaffected, however it's good practice to routinely check your produce for the presence of QFF larvae by cutting it into quarters, to improve the chance of detecting larvae.
If you have any unwanted or neglected QFF host produce trees, its best to remove or manage them to reduce the risk of attracting QFF.
Adult fruit fly activity can be monitored by using traps containing synthetic attractants. The most commonly used attractant (or lure) is Cuelure, which attracts and kills only male QFF. Traps are placed in the shade of the canopy of host trees and the contents checked on a weekly basis during the fruit fly season and then fortnightly during the winter months.
Greater Sunraysia PFA: If enough flies are detected in an area of the PFA, an outbreak is declared and the boundaries of the outbreak zone are defined. Restrictions apply to QFF host produce moving from an outbreak zone to other parts of the PFA.
When no fruit flies have been trapped within a PFA outbreak zone for a prescribed period, the outbreak is considered to be eradicated and the zone can be reinstated as being free of fruit fly. The length of the prescribed period varies according to the time of year when the last fly was caught and how this relates to the speed of the fruit fly's life cycle.
Baits can be used to reduce QFF numbers on-farm. They consist of a protein attractant mixed with an insecticide and are usually spot-sprayed onto the trunks or foliage of host trees.
Adult flies are attracted to the bait droplets as a food source and are killed by the insecticide.
QFF baits can be purchased from local chemical resellers.
Cover spraying can be used to directly control adult QFF on contact and destroy eggs and larvae within fruit. They contain contact or systemic insecticides and are sometimes mixed with a lure to help protect produce from initial fruit fly infestations. Cover sprays are generally applied to foliage and developing fruit and are available from your local chemical reseller. They should be applied according to the directions on the product label.
