The corn leaf aphid, Rhopalosiphum maidis (Fitch) is one of the most important pests of maize with worldwide distri- bution. The use of relatively resistant corn hybrids may lessen the harmful effects by this aphid; we therefore com- pared population growth parameters of R. maidis reared on six commonly grown maize hybrids in Iran, namely K3640/3MO17, Simon, SC704, EXP1, VRE26K18 and VRE27K18. The experiments were carried out under conditions of 251 o C, 6010% RH, and a photoperiod of 16L8D. The development time and survival of aphid nymphs differed significantly among the maize hybrids tested. We also observed significant differences in aphid fe- cundity, resulting in large variations in population growth parameters, such as the intrinsic rate of natural increase (r m ), net reproductive rate (R 0 ), finite rate of increase (l) and doubling time (DT). The r m values were highest for aphids reared on maize hybrids EXP1 and VRE27K18, lowest for aphids reared on hybrid K3640/3MO17, and in- termediate for aphids reared on hybrids VRE26K18, SC704 and Simon. Consequently, these results may offer use- ful information for planning a comprehensive program for IPM of the corn leaf aphid in Iran.
