In excess of 70 per cent mortality is observed during the overwintering stage of the life cycle of L. cuprina. The mortality is selective in the absence of a fitness modifier; phenotypes resistant to diazinon overwinter less successfully than susceptibles. In the presence of the modifier the overwintering success of all genotypes is similar. The effect is dominant. Laboratory and field experiments show that selection against resistant individuals increases with time in arrested development. The relevance of these results to the evolution of insecticide resistance is discussed.
在铜绿丽蝇生命周期的越冬阶段，观察到死亡率超过70%。在没有适应性修饰因子的情况下，这种死亡率具有选择性；对二嗪农有抗性的表型越冬成功率低于敏感表型。在有修饰因子的情况下，所有基因型的越冬成功率相似。这种效应是显性的。实验室和田间实验表明，随着滞育时间的延长，对抗性个体的选择作用增强。本文讨论了这些结果与抗药性进化的相关性。
