Queensland fruit fly in your garden - video transcript
[Narrator] Queensland fruit fly can be a problem for home gardeners and commercial growers because it attacks a large variety of fruit and vegetables, making them inedible. Queensland fruit fly spreads from infested plants to nearby fruit and vegetables, and by people sharing or travelling with home grown fruit or vegetables. While fruit and vegetables may look fine from the outside, they may be rotten or have eggs or maggots hidden inside. So what do Queensland fruit flies look like? Adult flies are approximately seven millimetres long and are reddish-brown in colour, with distinct yellow markings. Queensland fruit fly goes through four main stages of life.
The adult female Queensland fruit fly injects her eggs into host fruit, laying up to 100 eggs a day. Eggs are white and one millimetre long, which makes them hard to see. You may see tiny puncture marks in fruit. The eggs hatch into creamy yellow maggots that grow up to nine millimetres long. The maggots feed on the fruit, eventually chewing their way out. The maggots then burrow into the ground and change into oval, brown, hard pupae. After a few weeks, if conditions are suitable, the fruit flies come out of the ground and look for food around gardens.
After feeding and mating, females search for suitable ripe fruit to lay their eggs into, and their cycle continues. So if you want to grow fruit and vegetables in your garden, check for Queensland fruit fly and take steps to manage it before it spoils your produce or spreads to other properties. So to protect your garden, hang traps to monitor and catch Queensland fruit flies; apply baits and cover sprays to control Queensland fruit flies; pick up and dispose of fallen fruit; remove unwanted fruiting trees and vegetables; and net host fruit and vegetable plants.
