Russian Wheat Aphid Learnings from 2018 and how they can inform us in 2019 locations
Aims

To investigate regional risk and management tactics for RWA.

Key messages

• Contrary to expectations Russian Wheat Aphid pressure in Southern Australian cereal production seems low over the last years (2017, 2018). Dry and hot summer conditions seem to reduce green bridge survival of Russian Wheat Aphids.
• Barley grass and Brome grasses are major hosts (van Helden 2018) supporting RWA survival over summer. Their development will strongly depend on summer rainfall.
• Development of regional economic thresholds are in progress at trial sites throughout South Australia,Victoria, Tasmania, and New South Wales. Use of international thresholds are still advised until Australian thresholds are developed.
• Observations suggest that crop infestations occur in autumn on early growth stages, then persist over winter and can build up in spring, especially when plants are drought stressed.
