The Department of Primary Industries and Regional Development is responding to the
detection of a single Queensland fruit fly (Qfly) in Fremantle.

system against this pest.
“The department is conducting regular surveillance in the area, and has installed additional

Dr Hardie said further measures such as baiting with an organic pesticide were being
considered, and further advice would be provided to industry and the local community as more
information became available.
