To aid Russian Wheat Aphid management planning and development of cultural controls, there is a need to know what role green bridges play in supporting RWA populations.

This information will be used to develop predictive models that will estimate seasonal aphid risk within each affected region. Findings by cesar and SARDI will enable researchers to better inform advisers and grain growers about how to best manage this new pest.

Additionally, determining what beneficial insects are best placed to manage RWA is another big question that will be investigated.
