The proposal is for an intensive ten-month programme aimed at total eradication of the limited infestation of Queensland fruit fly in the Perth metropolitan area. The proposed eradication programme is based on baits formulated with either male only or combined male and female lures and containing between 1 and 2 g of the insecticide malathion, followed by a strategic release of sterile male fruit flies.

Urgent implementation of the eradication programme is proposed to avoid the spread of this pest to the major fruit growing areas of southwest Western Australia.

The Mediterranean fruit fly was successfully eradicated from the Carnarvon area in 1986 using a similar programme based on protein baiting and sterile male release. There were no reported negative environmental impacts arising from this programme.

Similar programmes have been undertaken in New South Wales, South Australia and overseas.
