Fruit fly activity

Fruit fly numbers are expected to increase in September as adult flies that survived winter become active as the weather warms up. Fruit that is ripening or ripe nearby may become infested with the new season’s fruit fly generation, so it’s important to pick up or harvest and destroy all unwanted fruit at this time of year.

Stop the spread

Queensland fruit fly (Qfly) will start to increase in numbers and are expected to be trapped earlier in urban locations than peri-urban and rural areas. It is recommende­d urban householde­rs clean up unwanted fruit, monitor for Qfly presence and, if needed, carry out fruit fly control practices.

It is suggested all home gardeners growing fruit and vegetables start building a supply of traps, nets and pesticides approved for home garden use and begin fruit fly management programs such as:

• Monitor Qfly presence with a trap or traps

• Check early or late-hanging fruit for fruit fly sting marks

• Cover fruit and vegetables with a net to keep Qfly out

• Clear away and destroy unwanted fruit

• Consider complete removal of unwanted fruiting plants, trees and vines

• Work with neighbours in controllin­g

Qfly – the more area-wide strategies set up the better for the whole community

Trapping informatio­n and activity

The Goulburn Murray Valley fruit fly trapping grid is used to identify likely spring hot spots, where and when Qfly management activities can be implemente­d and how effective management programs are performing. Past activity is an important trigger for increased monitoring and control.

Data from the regional fruit fly trapping grid has been examined to identify areas where fruit fly activity was located in recent years. The following areas recorded fruit fly activity in August and September in recent years through the regional trapping grid and require extra vigilance:

• Euroa

• Kyabram

• Mooroopna

• Shepparton

• Strathmert­on

• Yarrawonga

• Katamatite

• Merrigum

• Numurkah

• Tatura

• Tongala

New generation­s

Qfly mate at sunset as long as temperatur­es at dusk are above about 16˚C. Sunset temperatur­es have been high enough in the areas of Shepparton and Tatura in August for mating to occur. Extra precaution­s are recommende­d for these areas.
