Iranian false spider mite, Cenopalpus irani is one of main pests on apple trees and some fruit trees in Iran. The life table parameters of C. irani were determined on four apple cultivars (Kohanz Golab, Imperial Gala, Lebanon Red, and Granny Smith) under laboratory conditions at 25±1ºC, 60±5% RH, and a photoperiod of 16: 8 h (L: D). The longest and shortest developmental time of immature stages was observed in Kohanz Golab (46.02 days), and Granny Smith (22.60 days), respectively. The lowest and highest survival rate for whole immature stages was 82.85% and 90.00% on Kohanz Golab, and Granny Smith, respectively. The intrinsic rate of increase (r) ranged from 0.041 day-1 on Kohanz Golab to 0.089 day-1 on Granny Smith. The mean generation time (T) on the above-mentioned cultivars was 66.04, 55.28, 48.10, and 34.99 days, respectively. The fecundity was also affected by the cultivars; it was the lowest on Kohanz Golab (29.55 eggs/female) and highest on Granny Smith (37.93 eggs/female). The results of the data analysis of different apple cultivars based on some demographic parameters of C. irani mite showed that Granny Smith and Kohenz Gulab cultivars are the most sensitive and resistant hosts to this pest, respectively. The findings of the present study provide new information to design a more comprehensive IPM program for this pest in apple orchards.
