GARDENERS are urged to inspect their citrus trees for signs of citrus gall wasp.

The pest will be on the move as the weather warms up, and is an introduced pest in WA which could threaten the state’s valuable citrus orchards.

Department of Primary Industries and Regional Development technical officer Kevin Lacey said spring is the ideal time to monitor your backyard citrus trees and support the department’s annual Biosecurity Blitz campaign.

“Now is the time of year when the pest’s distinctive galls, or nests, start to appear on stems as woody bulges about 1-2cm long,” he said.

“The galls contain hundreds of larvae, which emerge as tiny black wasps from mid-September to early November.”

Reports of citrus gall wasp or any other pest or disease can be made on the MyPestGuide reporter app, the Pest and Disease Information Service on 9368 3080, or by emailing padis@dpird.wa.gov.au.
