Fruit fly activity
1. Queensland fruit fly (Qfly) trapping rates spiked in late August and early
September reflecting the emergence of adult fruit fly from their winter refuges.
2. Weather outlooks for October in the Goulburn Murray Valley (GMV) favour the
survival and egg-laying capacity of these fruit fly.
3. Early vigilance (looking for sting marks on fruit) and orchard hygiene (removal of
unwanted fruit and fruiting plants) will reduce the impact of the new Qfly
generation.
4. Qfly numbers will drop during October as these flies die out – leaving their eggs,
larvae and pupae in the landscape to replace them.
5. The GMV fruit fly trapping grid can be used to identify likely spring hot spots,
where and when Qfly management activities can be implemented and how
effective its Area Wide Management programs, including sterile insect technique
(SIT), are performing.
