通过构建棉铃虫Ｈｅｌｉｃｏｖｅｒｐａａｒｍｉｇｅｒａ（Ｈｕｂｎｅｒ）对氰戊菊酯抗性品系（Ｆｅｎ－Ｒ）和敏感品系（Ｓ）的实验种群生命表，比较了一系列生长发育和繁殖特征；并用净增殖率（Ｒ。）来确定两个品系的相对适合度。结果表明，Ｆｅｎ－Ｒ品系与敏感品系相比具有一定程度的繁殖不利性，包括雌蛾交配率降低，每头雌蛾的平均产卵量减少以及较低的卵孵化率；没有观察到Ｆｅｎ－Ｒ品系在生长发育上的不利性。Ｆｅｎ－Ｒ品系相对于敏感品系具有０．６９的适合度。
A series of growth and reproduction characteristics were compared with the experimental population life table of Helicoverpa armigera (Hubner) against fenvalerate resistant strain (Fen-R) and susceptible strain (S). The net reproductive rate (R. ) To determine the relative fitness of the two lines. The results showed that the Fen-R strain had some degree of reproductive disadvantage compared to the susceptible strain, including decreased female mating rate, reduced average fecundity per females, and lower hatchability of the eggs; no evidence of Fen- R strains in the growth and development of the unfavorable. The Fen-R strain has a fitness of 0.69 relative to the susceptible strain.
