英文摘要	本实验研究了小菜蛾Plutella xylostella L.高抗CrylAc种群DBMlAc-R(抗性倍数大于1000)及敏感种群DBMlAc-S的生长发育、繁殖等生物特征情况,组建了两种群的生命表,并对其适合度进行了研究。结果表明,DBMlAc-R的产卵量、卵历期、孵化率和化蛹率、蛹重及雌雄比(♀:♂),均显著低于DBMlAc-S。DBMlAc-R相对于DBMlAc-S的相对适合度为0.5762,表明CrylAc抗性种群在繁殖能力上存在明显的生存劣势。; A resistant strain (DBMlAc-R) of Plutella xylostella L. (diamondback moth) with more than 1 000-fold resistance to CrylAc was obtained. Life history characteristics, such as the development and fecundity of susceptible (DBMlAc-S) and resistant strains, were studied. Life tables were established and the relative fitness cost of developing resistance analyzed. The results show that the DBMlAc-R strain has distinct reproductive disadvantages, such as a fitness value of 0.5762, including lower fecundity, hatching rate, pupation rate and sex ratio (♀:♂), shorter egg period and lighter pupa weight, compared with the non-resistant DBMlAc-S strain.
