Does the origin of Helicoverpa punctigera populations explain their susceptibility to agricultural insecticides?

通过建立斑点夜蛾种群的地理起源和迁徙模式(通过基因流)，并将其与澳大利亚杀虫剂抗性的发生和持续直接相关(通过描述已知杀虫剂敏感/抗药性状态的昆虫的运动)，本研究将极大地促进我们对杀虫剂抗性的发展和传播的理解。这些知识将使农业能够使用杀虫剂，从而减少杀虫剂喷洒失败的频率，并减少抗药性虫害暴发造成的作物损失。

By establishing the geographic origin, and migration pattens of H. punctigera populations (by gene-flow), and directly relating it to the occurrence and persistence of insecticide resistance in Australia (by describing the movement of insects with known insecticide susceptible/resistant status), this research will greatly advance our understanding of how insecticide resistance develops and how it spreads. This knowledge will enable the agricultural industry to use insecticides so as to reduce the frequency of insecticide spray failures, and reduce crop losses caused by insecticide resistant pest outbreaks.
