Abstract： [Objectives] To assess the effects of different control methods on the population dynamics of wheat aphids and provide a theoretical foundation for controlling wheat aphids in the field. [Methods] The effects of different kinds of control (yellow board traps, sugar vinegar mixture, lures, light trapping and comprehensive prevention) on the population dynamics of wheat aphids were measured during the wheat growing period and compared to those in a non-treatment field. [Results] Light trapping was superior to yellow board traps and sugar vinegar mixture, but its effect on winged Rhopalosiphum padi was not obvious. The effects of yellow board traps and sugar vinegar mixture liquid were obvious. Integrating different control methods was very effective in controlling wheat aphids. [Conclusion] A variety of control methods are better than one. The effectiveness of light trapping, sugar vinegar mixture, yellow board traps and lures varied depending on the species of wheat aphid. Different control methods may be appropriate for different stages of the wheat growth period.
