Diptera: Family: Tephritidae Qld. Fruit Fly: Dacus tryoni


What are Fruit Flies

Small flies with a reddish-brown body and red eyes. Queensland fruit fly has yellow markings on the body. Fruit fly is attracted to ripening and fermented fruits and vegetables. Fruit can be stung when they are just changing colour or later. The adult fly lays the eggs just under the fruit outer surface. This is the time that insecticide is effective on fruit fly. When the larvae hatch, they tunnel into the fruit centre and their feeding causes the fruit to rot. At this point, chemical control is largely ineffective. Numbers of fruit fly build up in warm moist weather, for example, wet summers and autumns. Fruit fly attacks a large range of host plants which include avocados, bananas, citrus, stonefruit, passionfruit, tomatoes and capsicums. 

Garden hygiene is also important in controlling fruit fly.  All infected fruit should be gathered and destroyed by burning or boiling.  These measures are compulsory in most states.  In South Australia, householders suspecting the presence of fruit fly should ring the Fruit Fly Hotline 1300 666 010 so that Biosecurity SA can take the necessary steps to identify the pest and eradicate it.


How to Protect your plants against Fruit Flies

There is no need to apply the product directly on fruit.  It can instead be sprayed on the lower trunk or foliage.  Hormone based lures, for example, Dak-pots, which attract male fruit flies, are useful indicators of fruit fly activity.

Continue to apply Yates Nature’s Way Fruit Fly Control on fruit trees and plants to attract and kill adult fruit flies. And practice good garden hygiene by picking up any affected fruit, placing in a sealed plastic bag and putting in the garbage.



Sting marks may show up as yellow spots or oozing gum.
