Sheep blowfly strike reduction using a synthetic lure system

The effectiveness of a synthetic lure system to reduce the incidence of blowfly strike in sheep flocks was assessed, using randomised field trials. Four field trials used eight total groups of sheep randomised to treatment (flytrap) or control on two properties in southern Queensland between 1999 and 2001. Treatment consisted of the operation of flytraps in paddocks as per manufacturer's recommendations. All sheep were inspected physically each month for flystrikes. Flytraps were associated with a reduction in flystrike incidence of 38-55%, compared to control sheep. Results confirm that traps are a useful component of a flystrike-control program. The use of fly traps by a substantial proportion of woolgrowers could assist the Australian wool industry to meet targets of reduced pesticides on shorn wool.
