Abstract： [Objectives] To determine the effects of different methods of wheat aphid control on the arthropod community in wheat fields and provide a basis for in depth study of biological diversity in wheat fields. [Methods] The effects of yellow plate traps, light traps, sweet and sour liquid and comprehensive control of wheat aphids on other arthropods in wheat fields was compared. [Results] The comprehensive use of yellow plate traps, light traps and sweet and sour liquid can improve the stability of the insect community but can also reduce the species abundance of both wheat aphid and natural enemies. The stability of the predatory natural enemy community was poor under all the aphid control measures tested. To some extent, the use of single control measures can affect the relative abundance of the insect community, the stability of aphids and their sub-communities and the stability of the predatory natural enemy community. [Conclusion] Different aphid control methods have different effects on the wheat field ecosystem.
