Abstract：To examine the effects of different apple varieties on growth, development and reproduction of Adoxophyes orana, the developmental duration, survival rate and fecundity of Adoxophyes orana on six apple varieties ( Janet, Giant Janet, Jonathan, Zhuguang, Starkrimson and Golden Delicious) were measured under laboratory conditions of (26 ±1)℃, (80 ±5)% RH and photoperiod of 16L∶8D.And respective life tables were established.The results showed that the developmental duration of Adoxophyes orana exhibited significant differences on six apple varieties, among which, that on Janet was the shortest (33.95 d) and that on Jona-than was the longest (39.76 d).The average fecundity on Jonathan was the highest (107.24 eggs/female), followed by Janet (85.00 eggs/female).However, there was no significant difference on the survival rate. The parameters such as net reproduction rate ( R0 ) , intrinsic rate of increase ( rm ) and finite rate of increase (λ) were the greatest on Janet, and the mean generation time ( T) and population doubling time ( Dt ) on Janet were the shortest.It indicated that Janet was the best host plant for Adoxophyes orana among the six vari-eties.
