Now is a good time to check for citrus gall wasp, which has previously been found in the Swan Valley, according to the Department of Primary Industries and Regional Development.

Time to check for citrus pest

GARDENERS are being urged to inspect their citrus trees for signs of citrus gall wasp, a pest which will be on the move as the weather warms up.

Citrus gall wasp is found on the east coast but it is considered an introduced pest in Western Australia, which could threaten the state’s citrus orchards.

The pest was first found in WA in 2013 and since then has been detected in several gardens in the north-eastern suburbs, as well as the Swan Valley, but has yet to become established in WA’s citrus growing regions.

The Department of Primary Industries and Regional Development recently updated its website with additional information about how to identify, report and stop the spread of citrus gall wasp, which affects all types of citrus.

Technical officer Kevin Lacey said spring was an ideal time to monitor backyard citrus trees.

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

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

Residents can report signs of citrus gall wasp via the free MyPestGuide Reporter app.

The MyPestGuide Reporter app allows users to take up to four photographs of the pest or symptoms and sends the report directly to the department for identification.

In return, experts provide information about biosecurity pests, and its control.

Reports of citrus gall wasp or any other pest or disease can also be reported
to the department’s pest and disease information service on 9368 3080 or email [email protected]
