An analysis by fruit fly expert Andrew Jessup projects a potential increase in Queensland Fruit Fly (Qfly) populations in the Goulburn Murray Valley (GMV) by 2026. Without adequate funding for an Area Wide Management (AWM) program, Qfly numbers could rise by 205% in the best-case scenario and over 600% in the worst-case scenario. The analysis considers weather and climate factors, emphasizing the need for a well-funded AWM program to manage fruit fly populations effectively.
The Victorian Government's initial Fruit Fly Program in 2017/2018 resulted in a 95% reduction in fruit fly numbers in its first year, with a further 60% reduction the following year. However, since 2020/2021, funding has decreased by 62.5%, impacting the program's sustainability. The government plans to cease funding entirely by June 2025. This reduction in support has led to less proactive management, particularly in urban areas where Qfly breeding significantly impacts rural orchards.
Horticulture in the GMV contributes $1.6 billion to the Gross Regional Product and is a key job provider, with Victorian horticulture accounting for 30% of Australia's total gross horticultural value in 2021/2022. Exports from Victoria made up 45% of the nation's horticultural exports during the same period. Qfly management is crucial to maintaining this economic contribution, as growers currently bear high costs to protect their crops using baits and sprays.
Jessup highlights the success of the high-input AWM strategy in managing fruit fly populations, noting the collaboration between the State Government and local growers. The GMV AWM program has received multiple awards and was recognized at the 11th International Symposium on Fruit Flies of Economic Importance.
Cobram District Fruit Growers Association Chair Adrian Conti and GMV Fruit Fly Governance Group Chair Tony Siciliano stress the importance of continued government support to protect horticulture and maintain the region's export reputation. Greater Shepparton Mayor Cr Shane Sali underscores the economic reliance on horticulture, urging the Victorian Government to extend the program beyond June 2025.
