Abstract: The influence of chemical compositions of "8455" wheat plant under two fertilization levels on population dynamics of Schizaphis graminum and Macrosiphum avenae is studied. The results show that soluble carbohydrates, potassium and water contents of wheat plant significantly affect the population dynamics of Schizaphis gramninum and cystine content is the main factor affecting the population dynamics of Maocrosiphum avenae.
