The influence of leaf pubescence of three wheat cultivars (Pishtaz, Ghuds and Falat) on preference and biological parameters of Sipha maydis (Passerini) were investigated under greenhouse conditions (25 ± 2 °C, 70 ± 10% RH and 14:10 h (L: D) photoperiod). The results showed that Pishtaz had a maximum density of trichomes compared to the other cultivars. In the preference test with whole plant, the number of aphids on Pishtaz was significantly greater than that on other cultivars at 48 hrs after infestation. Similarly, in the preference test with leaves, the numbers of attracted aphids per leaf was highest on Pishtaz. In the life table study, there was no significant difference of intrinsic rate of natural increase (rm) among the three studied cultivars but it was highest on Pishtaz (0.187 /day). Aphids’ net reproductive rate, doubling time, mean generation time and finite rate of increases did not show significant difference between the tested cultivars. According to our results, leaf surface pubescence of wheat is not an effective resistance mechanism against S. maydis.
