Abstract: Wheat aphids are important pests of wheat in Chinaand the planting of resistant wheat crop varieties is an efficient and environmentally friendly means of controlling aphids that can reduce pesticide use, protect natural enemies, and improve the ecological environment of wheat fields. This paper introduces progress in research on three classical mechanisms by which wheat is made resistant to aphids; physical resistance, chemical resistance and induced resistance. The relationship between aphids’ geological population (or biotype) to varietal resistance, the inheritance of resistance, and the application of non-host resistance are also reviewed and directions for future research discussed.
