[Method] In 2014, the control effects of sophocarpidine, pymetrozine, beta-cypermethrin, acetamiprid, imidacloprid, and chlor- pyrifos on wheat aphids were tested, and every pesticide was designed with three doses in Shou County, Anhui Province, to explore the significance of differences on control effects. [Result] The results showed that the control effects of the 6 insecti- cides were satisfied, and the insecticides were safe on wheat. [Conclusion] During initial diseasing stage of aphid, it is recommended to use sophocarpidine soluble concentrate (1.5%), pymetrozine water dispersible granule (50%), imidacloprid wet- table powder (25%), and acetamiprid wettable powder (5%), and chlorpyrifos missi- ble oil (40%), cypermethrin missible oil (4.5%) and imidacloprid wettable powder (25%) can be applied in peak-diseasing stage.展开更多
