| 摘 要： | 通过建立抗性品系和敏感品系的种群生命表,比较麦长管蚜Sitobion avenae(Fabricius)抗吡虫啉品系和敏感品系的生殖力差异,结果表明,抗性品系适合度显著下降,世代历期延长,成蚜寿命缩短;在繁殖上表现为产仔量下降,生殖期缩短。以净生殖率(R0)和内禀增长率(rm)来评价抗性品系的相对生物适合度,抗性品系分别是敏感品系的0.5200和0.7481。因此,麦长管蚜对吡虫啉的抗性品系存在显著的生殖劣势。

| Abstract: | The fecundity difference between the resistant strain (R) and the susceptible strain (S) of Sitobion avenae(Fabricius) was evaluated by constructing life tables. The results revealed that R strain showed developmental disadvantages, including prolonged nymphal duration and shorter adult longevity, as well as reproductive disadvantages such as lower effective fecundity and shorter fecundity stage. Compared the net reproductive rate (R_0) and intrinsic rate of increase (r_m) with S strain, the relative fitness value of the R strain was calculated to be 0.5200 and 0.7481, respectively. The imidacloprid-resistant strain had obvious reproductive disadvantages compared to the susceptible strain. |
