摘要: 为比较亚致死剂量毒死蜱对灰飞虱抗性和敏感品系种群动态的影响,采用生命表构建法研究了两个品系在亚致死剂量处理下种群生命参数的变化。结果表明,亚致死剂量(LC14)毒死蜱对抗性和敏感品系种群的发展均有明显的抑制作用。与对照相比,抗性和敏感品系若虫死亡率显著上升,发育历期延长,成虫寿命缩短,繁殖力下降,内禀增长率以及相对适合度下降。而且LC14剂量毒死蜱对抗性品系的影响小于敏感品系。药剂处理后,抗性品系繁殖力下降19.89%,明显低于敏感品系(38.29%);相对适合度下降24%,也低于敏感品系(48%)。

Abstract: In order to study the sublethal effect of chlorpyrifos on   resistant and susceptible Laodelphax striatellus populations,   life parameters  of L. striatellus  were analyzed by construction of   life tables. The results showed that the population development of the resistant or susceptible strain  was significantly inhibited by the sublethal doses of chlorpyrifos (LC14). Compared with that of  the untreated populations, nymph mortality was significantly increased, developmental duration extended, adult longevity shortened, fecundity declined, and  the intrinsic growth rate and relative fitness decreased in chlorpyrifos treated populations. Moreover, fecundity decline of the resistant strains(1989%) was significantly lower than that of the susceptible strain (39.29%) and relative fitness decrease of the resistant strain(24%) was significantly lower than that of the susseptible strain(48%) after treated with  LC14 of chlorpyrifos,  implying  the less  inhibition of chlorpyrifos on the resistant strain than  on the susceptible strain.
