Insects have a cunning ability to respond to damaging environments by evolving genetic resistance or mobilising metabolic tolerance mechanisms. Recent observations of inducible tolerance to synthetic and biopesticides, which can be transmitted to offspring by a maternal effect has the potential to cause ecological and economic problems in agricultural production. We will use field-collected Diamondback moth (DBM), a major insect pest in canola and brassica vegetable crops, to investigate the genetic implications of inducible tolerance for the integrated management of DBM and for the design of new resistance management strategies.

昆虫有一种狡猾的能力，通过进化遗传抗性或调动代谢耐受机制来应对破坏性环境。最近观察到对合成和生物农药的可诱导耐受性可通过母体效应传递给后代，这有可能在农业生产中造成生态和经济问题。我们将使用现场收集的小菜蛾（DBM），在油菜和芸苔属蔬菜作物的主要害虫，调查的遗传意义的诱导耐受性DBM的综合管理和设计新的抗性管理策略。
