Spirotetramat resistance in Australian green peach aphids

The resistance of green peach aphid (Myzus persicae, GPA) to numerous chemical mode of action groups makes it an ongoing management challenge. In Australia, GPA has evolved high-level resistance to synthetic pyrethroids and carbamates, and low-level resistance to organophosphates and neonicotinoids. Quite recently, low-level resistance to sulfoxaflor has also evolved in some Australian field populations.

Research published in 2022 found populations of GPA with resistance to spirotetramat, the active ingredient in Movento® 240 SC Insecticide, as well as several generic products containing the same active ingredient. Spirotetramat, a Group 23 insecticide, is an important tool in GPA management in vegetable crops in Australia.
