Insecticide resistance testing of green peach aphid (Myzus persicae, GPA) is being offered to grain growers and advisors.
Green peach aphid is a major pest in canola and pulse production in Australia. This species’ ability to quickly evolve resistance to chemicals makes it a difficult pest to manage. It has developed resistance to multiple insecticide groups in Australia, including carbamates, synthetic pyrethroids, organophosphates, neonicotinoids, sulfoxaflor, and spirotetramat.
The GRDC is supporting a 4-year investment to reduce the impact of GPA and turnip yellows virus (TuYV). Led by Cesar Australia, the project seeks to provide grain growers and advisors with improved insecticide resistance management strategies and extend the life of effective chemical control options.
As part of the project, we are restarting our grower resistance surveillance program.
If you have encountered:
- GPA populations that have survived a chemical application
- GPA populations with suspected chemical resistance
- Other aphid species present where there are control failures
we want to hear from you!
Email Dr Alex Slavenko (aslavenko@cesaraustralia.com) describing what you’ve experienced. If we suspect you have resistance, we will ask you to send us a sample. We’ll run a full test for resistance to all commonly used insecticide modes of action, then send you a detailed report summarizing the chemical sensitivity of your GPA sample, plus recommendations for management.
Your sample won’t just help you, it will also inform the broader national resistance surveillance monitoring Cesar Australia is leading, and help the entire industry be better prepared to handle emerging chemical resistances in this economically important pest.
Join the national effort to tackle insecticide resistance—starting with your paddock.
