Research into new tick control measures considered

14/11/2002

Gene markers for tick resistance in cattle and biological controls such as fungi are some of the areas being considered for research and development (R&D) for tick control in the Australian beef industry.

More than 50 researchers, scientists and industry representatives gathered at a recent Meat and Livestock Australia (MLA) workshop in Brisbane to consider existing tick control measures and discuss options for future R&D.

MLA veterinary manager Dr Peter Rolfe said there was emerging resistance to existing chemical tick control measures and as such these controls had limited lifespans.

In addition, increasing use of less tick resistant breeds in crossbreeding programs in northern Australia meant these cattle were more susceptible to ticks and tick fever.

"While an effective tick vaccine is available, it is not widely used in the beef industry due to the high frequency of treatments required," Dr Rolfe said.

"One of the research areas being considered is to look at means to reduce the number of vaccine treatments required."

Other areas being considered for research include the identification of gene markers for tick resistance and the development of potential biological controls such as fungi.

"Right now it is important producers follow best practice recommendations when using chemical controls to help delay the spread of resistance," he said.

Decisions on investment in R&D for tick control are expected to be made during the next 12 months.
