This project plans to compare the genomes of archived and contemporary specimens to discover how two key Australian pest moths have adapted to insecticides, aiding prediction of how they may respond in the future. Agricultural pest species are often capable of rapid adaptation to insecticides, resulting in widespread genetic resistance. Does this resistance build on existing genetic variation, or are fresh mutations used to produce a fast adaptive response? How do adaptive strategies differ among key Australian pests? This project aims to answer these questions and advance understanding of mechanisms that underpin rapid evolution to improve approaches toward pest management and agricultural protection.

该项目计划比较存档标本和当代标本的基因组，以发现两种关键的澳大利亚害虫蛾是如何适应杀虫剂的，这有助于预测它们未来可能会如何反应。农业害虫物种往往能够快速适应杀虫剂，导致广泛的遗传抗性。这种抵抗力是建立在现有遗传变异的基础上，还是新的突变被用来产生快速适应反应？澳大利亚主要害虫之间的适应策略有何不同？该项目旨在回答这些问题，并增进对支持快速进化的机制的理解，以改进虫害管理和农业保护的方法。
