摘　　要：土耳其斯坦叶螨Tetranychus turkestani(Vgorag et Nikolski)是新疆棉花害螨的优势种,本试验通过调查土耳其斯坦叶螨对棉田为害程度,研究了土耳其斯坦叶螨对新疆主栽的6个棉花品种(系)的种群动态进行了比较:新海21号、新陆早26号2个棉花品种上叶螨密度水平较低,标杂A1、297-5、81-3、新陆早12号叶螨密度没有显著差异。在此基础上比较了6种品种(系)上土耳其斯坦叶螨的实验种群参数:土耳其斯坦叶螨在新海21号、新陆早12号、新陆早26号品种上各虫态发育历期较长,各虫态存活率较低,每雌产卵量较少,种群趋势指数较低;而在标杂A1、297-5、81-3品种上的发育历期较短,各虫态存活率较高,每雌产卵量较多,种群趋势指数也较高。Tetranychus turkestani （Vgorag et Nikolski） is a dominant pest mite species on cotton in Xinjiang. Population dynamics and life table parameters of T. turkestani on 6 main cotton cuhivars in Xinjiang were compared. Population densities of T. turkestani were lower on Xinhai 21 and Xinluzao 26, and those of T. turkestani were higher on the Biaoza A1 81-3, Xinluzao 21 and 297-5. The development duration of each immature stage of T. turkestani on Xinhai 21, Xinluzao 12, Xinluzao 26 were longer, the fecundity were lower, population trend index were lower, but there were the opposite effect on the Biaoza A1, 297-5, 81-3.
