| 摘 要： | 为了正确地评价不同桑树品种上朱砂叶螨为害差异，本文通过使用Jackknife方法(刀切法)，采用合适的生殖力生命表构建方法，对朱砂叶螨实验种群在不同的4个桑树品种上生殖力表的内禀增长率进行了统计推断。结果表明，温度为28±1℃、相对湿度75%±10%、光周期16L∶8D的条件下，西农6071 (山桑 Morus bombycis Koidz.，2x)、和田白桑 (白桑 M. alba Linne, 3x)、新一之濑 (白桑 M. alba Linne, 2x)和大石(广东桑 M. atropurpurea Roxb.， 3x) 4个桑树品种上朱砂叶螨rm值大小依次为0.41894（0.41043～0.42746）、0.37065（0.36604～0.37526）、0.36171（0.35778～0.36563）和0.35253（0.34757～0.35748）。通过对“伪值”样本同秩的成对t检验比较，这4个桑树品种对朱砂叶螨内禀增长率的影响有显著差异。结果说明朱砂叶螨对4种桑树的易感性，以西农6071、和田白桑、新一之濑、大石顺序渐弱。

| 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℃, 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.
