A strain of Helicoverpa armigera with 171‐fold resistance to indoxacarb was introgressed with a susceptible strain by serial backcrossing and reselection with indoxacarb resulting in the creation of the near‐isogenic GY7‐39BC4 strain. Fitness was compared on artificial diet under diapause and non‐diapause conditions in resistant, susceptible and F₁ progeny from a reciprocal backcross of the two strains using life history trait analyses. Selection experiments were used to determine stability of resistance.

耐茚虫威的棉铃虫Helicoverpa armigera（鳞翅目：夜蛾科）的近等基因菌株中的相对适应性和抗性稳定性。

通过串联回交并用茚虫威重新选择，将对茚虫威具有171倍抗性的棉铃虫菌株渗入易感菌株，从而产生了近等基因的GY7-39BC4菌株。使用生活史特征分析，在滞育和非滞育条件下，对两种菌株的互作回交的抗性，易感性和F ₁子代在滞育和非滞育条件下的适应性饮食进行了比较。选择实验用于确定电阻的稳定性。
