The main wheat aphids are Sitobion avenae （Fabricius）, Rhopalosiphum padi （Linnaeus）, Metopolophium dirhodum （Walker）, and Schiza- phis graminum （Rondani）. In the Huang-Huai area of China, the dominant wheat aphid species are S. avenae and R. padi. For many years, farmers have applied chemical pesticides to control wheat aphids. The number of wheat aphids in north China has increased from year to year, probably due to the increased resistance to insecticides.展开更多
