中文摘要：为了研究转基因棉花对北疆叶螨优势种土耳其斯坦叶螨Tetranychus turkestani （Ugarov et Nikolskii）种群生命参数的影响，本实验以常
规棉中棉49 作为对照，构建了叶螨在单价转基因棉新棉33B（Bt）、双价转基因棉中棉41（Bt+CpTI） 上的室内种群生命表。结果表明，单双
价转基因棉对叶螨的生长发育历期及生殖参数并没有明显影响；且取食常规棉的叶螨种群参数净生殖率、内禀增长率、平均世代周期、种群加
倍时间、周限增长率、存活曲线也与单双价棉无显著差异，这说明转基因棉对棉叶螨的生长发育、繁殖及种群增长并无显著影响.
英文摘要：An investigation was made into the effect of transgenic cotton on the life table parameters of Tetranychus turkestani
(Ugarov et Nikolskii), which is the dominant mite species in northern Xinjiang. Experiments were conducted to construct life
tables for T. turkestani on univalent transgenic cotton Xinmian 33B(Bt), the bivalent transgenic cotton Zhongmian 41
(Bt+CpTI) and conventional cotton Zhongmian 49 Univalent transgenic cotton or bivalent transgenic cotton had no obvious
effects on mites developmental period or fecundity parameters. Furthermore, there was no significant difference in the net
reproductive rate, intrinsic rate of increase, mean generation time, doubling time and finite rate of increase between T.
turkestani fed on transgenic cotton and and T. turkestani fed on conventional cotton, suggesting that transgenic cotton does
not affect the development, fecundity and populations of cotton mites.
