QUEENSLAND FRUIT FLY COMMUNITY UPDATE
Fruit Fly trapping
The majority of Queensland Fruit Fly (QFF) trapped since spring has been trapped in urban locations. During September 138 QFF were trapped in urban sites while only eight were trapped in rural sites. These are adult flies that overwintered successfully in favourable spots in urban areas. QFF are starting their population build up in urban areas and unless they are controlled they will impact on fruits and vegetables ripening in late spring, summer and autumn in urban gardens and, as they did last year, in commercial orchards in autumn.
Take action now
Now is the time to do the below jobs: 1. Place out or, if you already have them out, recharge (with new lures) fruit fly traps in yards. Use both maletargeting and female-targeting traps. Contact the GMV Regional Fruit Fly office or speak to your local nursery, produce store or hardware store for advice on what traps to use. 2. Check fruit that is ripening now for fruit fly infestation. If you find infestations, remove and destroy fruit. 3. If QFF have infested your fruit and/ numbers in your traps build up to around 5 QFF per fortnight you should undertake active QFF management such as netting and baiting. If you are unsure, speak to your local horticulture supplier.
Remove unwanted trees
The Free Tree Removal program has been extended to include periurban and rural residential properties. Applications will be assessed and prioritised according to the risk posed. Application forms can be collected from your Council’s customer service centre.
Checking fruit for infestations
If you have fruiting plants with ripening fruit in your yard, inspect them every couple of days from the beginning of September and throughout the season to check for fruit fly stings. Fruit to pay attention to include loquats, apricots and berries. Sometimes QFF sting marks can be seen on fruit as black spots surrounded by rotting tissue under the skin. The fruit can be cut open and searched for larvae (maggots) or a knife point can be placed into the skin under the sting mark and levered up to push eggs out through the wound. You will need a magnifying glass to see the eggs, as they are only 1.3mm long, 0.3mm wide and shaped like a milky white banana. Sometimes you can squeeze the fruit at the sting mark and the eggs then pop out through the wound. For assistance managing QFF, contact (03) 5871 9222 or firstname.lastname@example.org
