Citrus Gall Wasp, a pest of citrus trees in commercial orchards and home gardens, arrived in WA in 2013 and is spreading rapidly. This wasp poses a threat to the citrus industry in WA.
While the wasp has only been found in the Perth Metropolitan area to date, we are keen to keep this pest out of commercial orchards for as long as possible and require the assistance of your residents to do this.
Residents are encouraged to check their trees and use the department’s MyPestGuide Reporter app (mypestguide.agric.wa.gov.au/reporter) to report its presence or absence. These reports help us to keep track of the wasps spread.
The wasp could move into your area on infested trees from the Perth Metropolitan area. It is important to keep a close eye on any recently purchased or relocated trees and act quickly if galls appear.
Would you be able to help us by sharing information with your residents via your website, social media or newsletter?
