Özet
The development, survival rate, reproduction and biological parameters of the corn leaf aphid, Rhopalosiphum maidis (Fitch) on five corn cultivars were evaluated at 25 degrees C in laboratory conditions. The corn leaf aphid had longer nymphal development on CR 955 than the other cultivars. The lower percentage survival rate was observed on CR 955 than the others. The corn leaf aphid reared on AG 9229 had the highest fecundity (70.75 offspring/aphid). The net reproductive rate (R(o)) was the lowest (70.85 offspring/aphid/generation) on AG 9229. The intrinsic rate of increase (r(m)) was lower on CR 955 than the other corn cultivars. CR 955 showed resistance to the pest.
