Abstract: For wisely detecting resistance difference of mulberry cultivars to the carmine spider mite, Tetranychus cinnabarinus Boisduval, statistical inference on the intrinsic rate of increase of the mite on different mulberry cultivars (Morus L.) was conducted using Jackknife technique based on the life table data of the mite bred under laboratory conditions at 28±1°C, 75%±10% RH and a photoperiod of 16L:8D with different mulberry cultivars. The results showed that the rm values of Xinong6071 (M. bombycis Koidz., 2x), Hetianbaisang (M. alba Linne, 3x), Xinyizhilai (M. alba Linne, 2x) and Dashi (M. atropurpurea Roxb., 3x) were 0.41894 (0.41043-0.42746), 0.37065 (0.36604-0.37526), 0.36171 (0.35778-0.36563) and 0.35253 (0.34757-0.35748), respectively. Pairwise comparison t-tests were performed based on the respective ranks in Jackknife samples between different treatment groups with their respective P values. The results indicated that there existed significant difference between the rm values of the mite on different mulberry cultivars, and the susceptibility of the four cultivars of mulberry weaked sequentially in the order above.
