Summary

The trapping surveillance grid in the Goulburn Murray Valley (GMV) has revealed a buildup of the Queensland fruit fly (Qfly) populations from late February to March.

As urban crops decline with harvest and bird predation in the summer Qfly populations also decrease while peri-urban and rural increase. This reflects the movement of Qfly from urban, through […]

Summary

The majority of the Goulburn Murray Valley’s (GMV’s) commercial horticulture is harvested over the coming months. These crops will be prone to attack by Queensland fruit fly (Qfly). During this period Qfly populations will move away from the protection of fruitful refuges in urban areas of the GMV, to the more attractive commercial orchards surrounding […]

Fruit Fly Trends

Qfly numbers trapped have been on a downward trend throughout January due to excessively hot and dry weather conditions. Historically, there is a general upward trend between late February to early May, resulting in higher Qfly populations than those seen at present.

Adult and immature Qfly surviving extreme heat conditions will welcome rainfall, lower […]

Trapping Grid

On the 10th of December 2025 Greater Shepparton City Council announced it had secured $469,000 in Victorian Government funding to manage fruit fly across the municipal areas of Greater Shepparton, Moira Shire, Campaspe Shire and Strathbogie Shire Councils. A new Goulburn Murray Valley (GMV) fruit fly trapping grid is currently being installed and is […]
