Further Polyphagous Shot Hole Borer detected within the City

News Update 3 July 2023

The Department of Primary Industry & Regional Development (DPIRD) has alerted the City of South Perth to a positive detection of the Polyphagous Shot Hole Borer (PSHB) in a Poinciana tree along Strickland Street in South Perth and Coral trees around James Miller Oval in South Perth and Kwel Court Playground in Karawara.

The reserves in Karawara and Manning are now PSHB quarantine zones, which means that plant material larger than 2cm wide is not permitted to be removed. These areas are still open to the public as normal. 

Quarantine will remain in effect for at least 6 months if no further detections are made. If more infested trees are located the quarantine period may extend.

In June 2023 PSHB was also detected in Neil McDougall Park in Como. DPIRD has scheduled the removal of the two affected trees and the park remains a PSHB quarantine area.

PSHB is a beetle native to Southeast Asia. The beetle attacks a wide range of plants by tunnelling into trunks, stems and branches.
