Gar­den­ers warned on cit­rus wasps

Comment News (Armadale) - - Street Watch -

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.

It 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.
