AWI Investing More on Fighting Flystrike

AWI is building on its earlier sheep genomic flystrike resistance work by increasing the human resources dedicated to wool issues. Australian Wool Innovation will spend an extra $950,000 to accelerate research into flystrike genomics and new extension workshops on breeding for natural flystrike resistance. This takes AWI’s investment in breeding for flystrike resistance related RD&E projects since 2005 to $9.9 million.

In August AWI also announced an additional $650,000 to fast-track further investigations into the development of a flystrike vaccine.

AWI Chairman Jock Laurie said flystrike remains one of the biggest challenges for Australian woolgrowers. “The breeding of more profitable naturally resistant sheep to flystrike is a core research project for AWI and we are putting more money into it. As the industry’s Wool2030 strategy highlighted, growers want to have confidence and tools to manage flystrike without mulesing. Evidence of increasing blowfly resistance to chemicals and the shortage in shearers are extra reasons why AWI will speed up this work.”

The new Breeding for Flystrike Resistance workshop is expected to have a similar format to existing successful AWI workshops “Ramping up Repro” and “Winning with Weaners”, with a practical approach.

The workshop resources will draw on existing information, including from AWI’s Breeding for Breech Flystrike Resistance flocks, the Merino Lifetime Productivity (MLP) Project and MERINOSELECT. The additional investment will create two post-doctoral positions targeted at flystrike, working on the Merino Lifetime Productivity Project and a range of further refinements to merino genetic benchmarking technology.

The new workshop builds on another AWI workshop that is currently being piloted.  SimpliFly, a one day workshop for woolgrowers looking to implement strategic flystrike control on their property, introduces the concept of breeding for flystrike resistance as part of a holistic whole of farm plan.

SimpliFly participants will explore the many short- and long-term flystrike management tools and strategies, including breeding, that are available to them to help combat flystrike. They will also work through practical activities that enable them to combine these strategies and tools on their own property according to a customised annual flystrike management plan that best suits their specific circumstances.

The six planned pilot SimpliFly workshops have been delayed by Covid 19, but the first 2 will be held in NSW from late October, and further pilots are to be held early next year in Tasmania, SA and WA.

SimpliFly pilots will in turn inform the development of the Breeding for Flystrike Resistance workshops, which are expected to be piloted from mid-2022.The workshops will draw on the information and interactive decision tools that are available on

While the immediate focus to reduce the risk of flystrike is on lower wrinkle, dags, urine stain and cover, further genomic R&D provides the opportunity for these traits to be genomically enhanced, to create a stand-alone Breech Strike ASBV and provide genomic tools to assist wool growers that are not part of the ASBV system. The search for variations in the DNA associated with flystrike risk (or alternatively susceptibility) has long been a vision for the wool industry. All existing flystrike phenotypes and genotypes need to be pooled and analysed and further data needs to be collected to achieve these outcomes.
