摘　　要：在实验室条件下[温度(26±1)℃,相对湿度(75±1)%,光照L∶D=16∶8]研究了烟粉虱在新疆棉田主栽品种新陆早8号、新陆早16号、新陆早17号、中棉35号、抗5和岱80棉花品种上的存活率、产卵量和寿命等,组建了实验种群生命表,估测了种群净增殖率(R0)、内禀增长力(rm)、平均世代周期(T)和周限增长率(λ)等生殖力参数.结果表明:烟粉虱在不同棉花品种上的形态大小、发育历期、存活率及产卵量均存在显著差异.比较烟粉虱种群在6种棉花品种上的世代存活率和繁殖力,其在新陆早16号上发育速度最快、产卵量最高,而在抗5上各种生命参数相对较低.新陆早16号是烟粉虱种群生长发育最适宜的棉花品种,其次为中棉35号,抗5是烟粉虱种群最不适宜的品种.The development, survival, reproduction, and life-span of Bemisia tabaci （Gennadius） on six major cotton varieties （Xinluzao 8, Xinluzao 16, Xinluzao 17, Zhongmian 35, Kang 5, and Dai 80） in Xinjiang were studied under the conditions of （26 ±1 ） ℃, relative humidity （75 ± 1 ） % , and illumination L： D = 16：8 in laboratory. The life table of the B. tabaci experimental population was established, and the population net reproductive rate （R0 ）, intrinsic rate of increase （rm ） , mean generation time （T）, and finite growth rate （A） were estimated. Significant differences were observed in the size, development duration, survival, and fecundity of the experimental population on the six cotton varieties. The fecundity and survival rate of B. tabaci were the highest on Xinluzao 16 and the lowest on Kang 5. Xinluzao 16 was the most appropriate host for the growth and development of B. tabaci population, followed by Zhongmian 35, while Kang 5 was the most unsuitable host.
