About Queensland Fruit Fly
Only two species of economically important fruit flies occur in Australia. One of these is the Mediterranean fruit fly (Ceratitis capitata) which permanently inhabits the growing areas of Western Australia.
The other is the Queensland fruit fly (QFF)(Bactrocera tryoni) which permanently inhabits parts of the Northern Territory, Queensland, New South Wales and some parts of Victoria.
Adult QFF are about six to seven millimetres long and are reddish-brown in colour, with distinct yellow markings.
It has a wing expanse of 10 to 12 mm, and has mostly transparent wings marked with brown veins. On the top of the thorax, there is a broad creamy, often pale, dorsal band running down the middle, with a well-defined, narrow pale yellow stripe on each side. The shoulders (humeri), are pale yellow also. The abdomen is constricted at the base, flared in the middle, and broadly rounded at the tip, the females with an ovipositor.
