Effectiveness of a synthetic lure to reduce blowfly strike incidence: preliminary observations.
The effectiveness of a synthetic lure system (Lucitrap) to reduce blowfly strike incidence was assessed in a field trial conducted on two properties located in southern Queensland, Australia. Nine hundred and fifty sheep were randomised to treatment (one or more Lucitrap per 100 sheep) and control paddocks. Sheep were physically inspected for flystrike each month between August 1999 and May 2000. On one property, the risk of flystrike in the control group was 1.86 times (95% confidence interval, 1.19-2.90) greater than that in the treatment group. On the other property, two cases of flystrike were detected in the control group, but no cases were detected in the treatment group. These preliminary observations suggest that the use of Lucitrap can reduce the incidence of blowfly strike by up to about one-half. Blowfly traps have a role in controlling flystrike in circumstances in which sheep are susceptible to flystrike and the likelihood of flystrike occurring is at least moderate. The use of fly traps could assist the Australian wool industry to meet targets of reduced pesticide use.
