July 2016 detection
In July 2016 one female Asian longhorned beetle was found in an industrial warehouse in Perth.
The Department of Agriculture and Food, Western Australia (now Department of Primary Industries and Regional Development) undertook surveillance and there were no further detections.
It is likely that the beetle was a single hitchhiker in imported cargo, however it is not known where the beetle originated.
Alert for industrial areas
DAFWA is asking industrial warehouses in receipt of imported cargo to keep a lookout for suspect beetles. Refer to these web pages to know how to recognise Asian longhorned beetle.
This beetle is most likely to arrive in imported timber and wood used for pallets and other packing materials from Asia or North America.
