Russian wheat aphid

Russian wheat aphid was first identified in a wheat crop at Tarlee on 13 May 2016. Since then, it has been found in many cropping regions across SA and in the Wimmera and Mallee regions of Victoria. The National Management Group has been declared it not technically feasible to eradicate from south-east Australia.

Following this declaration, the Grains Research and Development Corporation and entomology experts are calling on growers and advisers to find, identify, consider aphid numbers and economic thresholds and enact a management strategy (FITE) if needed. This involves:

  • Find - where and what to look for
  • Identify - how to confirm the identity of RWA and differentiate from other aphids
  • Thresholds - consider aphid numbers and take an economic threshold approach to spraying
  • Enact - enact an appropriate management strategy for your situation

Report sightings to the Exotic Plant Pest Hotline on 1800 084 881.
