Beetle bonanza in the Central Highlands

Central Highlands Regional Council, Media Release, 29 June 2022

It might not be Paul, George, Ringo or John, but local farmers were thrilled to find another type of beetle on their Central Highlands property in March 2022, the Zygogramma bicolorata beetle.

‘It’s a very useful tool to help control parthenium, especially in a good ecological environmental system,’ said the local property owner.

The Zygogramma beetle, also known as the parthenium beetle or Mexican beetle, reduces the seed production of parthenium by eating the foliage and in some cases, can cause damage to the young flowering tops.

Biological control agents such as this beetle help to reduce parthenium’s density and vigour.

Property owners are continuing to work with members of the council’s ranger services team and the Burnett Catchment Care Association (BCCA) to collect these tiny beetles to spread across both regions.

‘We are continuing to monitor the Zygogramma population in the Central Highlands and are distributing to properties across our region,’ said General Manager John McDougall.

‘We have also traded several hundred with the North Burnett for Jewel beetles which will be an effective biocontrol for Cat’s Claw Creeper.’

Residents looking for biocontrol measures for their property are encouraged to contact council on 1300 686 242 to discuss options.
