Insecticide resistance in the green peach aphid: national surveillance, preparedness and implications for virus management

Insecticide resistance in the green peach aphid (Myzus persicae, GPA) continues to threaten canola and pulse production. There are diminishing chemical options available, and the functional diversity, prevalence and severity of resistances encountered in the field is increasing.

This investment enables the grains industry to track the status (distribution, severity, and mechanisms) of resistance evolution in GPA across Australian grain crops. An ongoing availability of knowledge and access to resistance maps and updated management tools will provide approaches to sustainably managing aphids and virus risk in grain crops, minimise yield losses, and reduce the likelihood of further GPA resistance issues.
