摘　　要：采用田间自然鉴定、室内种群生命表、种群繁殖增长倍数的试验方法,对8个茶树品种抗侧多食跗线螨(Polyphagotarsonemus latus Banks)的能力进行了鉴定.结果表明,蜀永1号抗螨性最强,蜀永3号抗螨性最弱,其余品种抗螨性居中.茶树品种对侧多食跗线螨抗性程度的鉴定,应把种群净增殖率,内禀增长率和繁殖增长倍数等几个重要生命参数结合起来进行综合评价,更为合理.The resistant ability of 8 varieties of tea to Polyphagotarsonemus latus Banks and the differentiate method were studied by means of both the differentiation in field test and analysis of the life table and the increase multiple of population. The results showed that the resistance of tea variety Shuyong 1 was the best, Shuyong 3 was the worst, the others were medium. For differentition of the resistant ability of tea variety, It was more reasonable that the important parameters of net productive rate,innate increase rate and increase multiple of population should be combined and synthetic apraised.
