Abstract: This paper deals with the effect of wheat varieties on main life parameters e.g., the survivals, growth and development, and reproduction of two wheat aphids Rhopalosiphum padi and Macrosiphum avenae, and analyzed the correlativity of experimental results in glasshouse and field. Ten wheat varieties were selected, which have been demonstrated the different resistance to wheat aphids in former field experiment. The results show that the resistance of these wheat varieties did not obviously affected the mortality of nymphal aphids, but significantly affected the development duration of nymphal aphids, and the longevity and fecundity of adults. The effect of various wheat varieties on the development duration of nymphal aphids of two species in glasshouse was correspondent with that in field. Therefore, the nymphal development duration could be used as one of the most important indexes identifying the anti aphid of wheat varieties. Moreover, the fecundity of R.padi adults in glasshouse was correspondent well with that in field.
