Abstract: 【Aim】 This study aims to ascertain the influence of different host plants on development and reproduction of the summer fruit tortrix moth, Adoxophyes orana. 【Methods】 The developmental duration and reproduction of the pest feeding on four host plants including peach (Amygdalus persica), apple (Malus pumila), plum (Prunus salicina) and apricot (Armeniaca vulgaris) were observed under laboratory conditions of 26±1℃, 80%±5% RH and a photoperiod of 16L:8D, and the life tables were constructed. 【Results】 The results showed that A. orana exhibited significant differences in the development and reproduction among the four host plants. The developmental duration of A. orana from egg to adult was the shortest on the apple (34.44 d) and the longest on the plum (38.37 d). The heaviest pupa was on the peach (28.25 mg/pupa) and the lightest was on the plum (17.93 mg/pupa). The higher survival rates of A. orana from egg to adult were found on the peach and apple (≥60.00%), while the lower survival rates were found on the plum and apricot, which were 45.00% and 50.00%, respectively. Female adults reared on the peach laid more eggs (96.15 eggs/female) than on the other host plants, and those reared on the apricot laid the fewest eggs (68.15 eggs/female). The net reproduction rate (R₀) of A. orana  was the highest on the peach (23.20) and the lowest on the apricot (11.66). The intrinsic rate of increase (r_m) of  A. orana was the highest on the peach (0.0953). The mean generation time (T) of A. orana  was the longest on the plum (35.72 d). The doubling time of  A. orana was the longest on the apricot (9.79 d), and the shortest on the peach (7.29 d). 【Conclusion】 The development and reproduction of A. orana are better on the peach and apple among the four host plants.
