Queensland fruit fly
Impact of Queensland fruit fly
Fruit flies are a significant phytosanitary threat to horticulture. They can have major impacts on Australia’s capacity to trade competitively in international markets. Effectively managing Queensland fruit fly ensures producers can develop, maintain and enhance access into domestic and international markets.
Queensland fruit fly (QFF) is a pest that requires everyone to be involved in controlling the insect and restricting its spread. The main way that QFF spreads to new areas is by being carried in infested host fruit and vegetables.
QFF has the potential to infest a wide range of horticultural crops, garden plants, native plants and weeds.
QFF host fruit cannot be transported into the New South Wales Fruit Fly Exclusion Zone (FFEZ), the Pest Free Area (PFA) or cross State borders unless the consignment is accompanied by industry certification arrangement or a permit issued by a State authority.
About the insect
QFF is different from the small dark brown drosophila flies (also called vinegar flies or ferment flies) that hang around ripe and decaying fruit. Drosophila flies are not agricultural pests but can be a nuisance where fruit and vegetables are stored.
QFF is native to eastern Queensland and north-eastern New South Wales. The ready availability of suitable hosts and habitat in urban and horticultural production areas in Queensland, Northern Territory, New South Wales and Victoria has enabled QFF to expand its natural range.
The Primefact 1186 Queensland Fruit Fly gives further details of the insect.
QFF is dependant on rainfall and moisture. In semi drought or low rainfall situations QFF is less likely to establish and can be controlled more easily than in high rainfall areas or when seasonal conditions are wetter.

Fruit Fly Exclusion Zone (FFEZ) and Pest Free Area (PFA)
Fruit and vegetable growing regions in designated areas in southern inland New South Wales, northern Victoria and South Australia are managed by the three states as the Fruit Fly Exclusion Zone (FFEZ) and the Greater Sunraysia Pest Free Area (PFA).
Host fruit or vegetables without a certificate or permit including host fruit and vegetables for household or personal consumption must be disposed of in quarantine bins before entering the FFEZ, PFA or crossing a State border. The location of roadside disposal bins is signposted.
