Fruit fly threat - help prevent an outbreak (Media Release: 28th March 2013)
Queensland Fruit Fly - Host Check List (PDF 1.1 MB )
Fruit flies are the world's worst fruit pest. They destroy fruit and vegetables - both commercial crops and those grown in home gardens.
The horticultural product of South Australia which is vulnerable to fruit fly infestation is currently worth $250 million annually.
To keep South Australia free of fruit fly, PIRSA has quarantine restrictions on the movement of fruit and vegetables into the state - both produce carried by travellers and on commercially imported produce.
It is important that quarantine restrictions on movement of fruit and vegetables are strictly observed as outbreaks of fruit fly only occur if maggot-infested fruit is brought into the state.
South Australia's front line fruit fly protection is provided by roadblocks that have been in operation for 50 years. More than 600 000 vehicles pass through these quarantine stations each year. Quarantine Inspectors are based at Ceduna, Oodla Wirra, Pinnaroo and Yamba. Honesty bins are located on other Highway entry points into the state. In addition, random mobile roadblocks operate throughout the state.
Australian Quarantine Inspection Service (AQIS) Detector Dogs operate at the Adelaide Airport and quarantine bins are strategically located on the terminals at the Great Southern Rail Terminal. Persons detected carrying fruit and vegetables past these points can be fined under the Plant Health Act 2009. Additionally PIRSA maintains a statewide permanent surveillance trapping grid. Each week Inspectors check traps at over 3800 locations. The trapping grid provides an early warning system in the overall prevention program.

People planning to visit fruit-growing regions along the River Murray in South Australia, Victoria and New South Wales known as the Fruit Fly Exclusion Zone (FFEZ) (PDF) are urged to observe restrictions on the transport of fresh fruit and vegetables into the zone and not bring fruit with them.
Biosecurity SA uses the Sterile Insect Technique (SIT) against outbreaks of fruit fly. This form of integrated pest management involves the release of large numbers of sterilised insects into the environment to mate with wild insects of the same species. Any eggs laid are infertile, eventually eradicating the fruit fly population.
Biosecurity SA Plant Health is involved with the NFFSP Project (external site) which aims to develop a national approach to fruit fly management.
You can find more information about the life cycle of fruit fly, how disease outbreaks can be detected and eradicated and what is being done to prevent outbreaks in South Australia in the attached Fact Sheet (HTML) OR Fact Sheet (PDF 667.6 KB ).

The Greater Sunraysia Pest Free Area is a new zone located within the existing Fruit Fly Exclusion Zone (FFEZ). It is renowned for the production of high value horticultural crops including citrus, table grapes and stone fruit. The Pest Free Area (PFA) is aligned to this production area to provide greater fruit fly control measures.
The Victorian and New South Wales Departments of Primary Industries (DPI) have introduced stringent legislative controls on the movement of host fruit and vegetables into the PFA to keep it free from the devastating pest, Queensland fruit fly. These strict controls on the movement of host fruit and vegetables have been introduced to maintain highly valuable interstate and overseas markets worth millions of dollars to ensure the area is free from fruit fly.
A detection of fruit fly within the PFA can result in the loss of lucrative export markets and the introduction of expensive control programs which affect the local fruit and vegetable industries and our communities.
