Russian Wheat Aphid in Tasmania

Russian wheat aphid, a serious insect pest of wheat, barley and some other cereal crops has been detected near Cressy in Tasmania.

It was first detected in Australia on 13 May 2016 in South Australia and then spread rapidly to Victoria and New South Wales. The National Management Group determined it was not technically feasible to eradicate the aphid for several reasons, including its wide distribution soon after detection.  It most likely spread to Tasmania on northerly airflows.

Russian wheat aphid, Diuraphis noxia, is a small green aphid whose feeding produces strong plant symptoms due to the injection of saliva into the plant. These symptoms include rolled leaves, chlorotic spots, leaf streaking, trapped awns giving a hooked appearance and stunted crop.
