摘　　要：研究结果表明:侧多食跗线螨种群在各品种上的田间密度有明显差异,平均螨量早白尖上最多,906最少。室内该螨在各品种上的发育历期、产仔动态、增长速度、生命参数均有明显差异。雌成螨历期蜀永3号最长,蜀永1号最短;产卵数以早白尖最多,906最少,内禀增长率蜀永3号最大,蜀永1号和906最小。因此,蜀永1号和906抗螨性强,蜀永3号抗螨性弱。The effects of 8 tea varieties on the population dynamics of yellow mite Polyphagotarsonemus latus (Banks) were systematically studied. The results showed that there were significant differences among field mean mite numbers on different varieties (highest on var. Zaobaijian and lowest on var. 906) and indoor developmental duration (of female, longest on var. Shuyong 3 and shortest on var. Shuyong 1), fertility (maximum on var. Zaobaijian and minimum on var. 906) and intrinsic rate of increase (highest on var. Shuyong 3 and lowest on var. Shuyong 1). Consequently, the var. Shuyong 1 and 906 are obviously resistant and var. Shuyong 3 is rather susceptible to yellow mite.
