Growers across Australia need to consider troublesome species of fruit fly: Queensland fruit fly (Qfly) and Mediterranean fruit fly (Medfly).
In WA, Medfly attacks a wide range of fruit and vegetables but it is not present in the eastern states of Australia.
In Queensland, NT, NSW, ACT and Victoria, Qfly is a perennial problem.
Tasmania and SA are fruit fly free and make considerable efforts to keep it that way.
In addition to reducing yields, Qfly and Medfly have implications for trade, both within Australia and overseas exports. Many markets will not accept produce from areas known to have these species.
Since the use of pesticides commonly used to tackle fruit fly infestations is no longer permitted (due to human health concerns) producers must rely on a suite of control methods used across the orchard and local area, known as area wide management.
This section includes an outline how the practice of area wide management can be used to manage fruit fly numbers. Topics include:
- Area Wide Management
- Bait spraying and Male Annihilation Technology
- Good orchard hygiene
- Cold treatment
