Discovering the pathways and mechanisms underlying bio-insecticide control of the global migratory pest, diamondback moth, Plutella xylostella.

维持作物产量和粮食安全是全世界关注的一个重大问题。本项目旨在通过深入了解苏云金芽孢杆菌（Bacillus thuringiensis, Bt）杀虫剂的作用方式，加强害虫防治策略，改善农业生物杀虫剂的使用。本研究旨在提高植物皂苷类生物杀虫剂的药效，并对开发植物皂苷类生物杀虫剂的机会进行评价。这将有助于确定抗药性飞蛾迁移到澳大利亚和在我国境内的风险。该项目旨在为改进转基因bt作物和bt喷剂提供机会，为新型生物杀虫剂的商业化开发提供机会，并为澳大利亚主要迁徙害虫制定最优控制策略。

Sustaining crop yield and maintaining food security is a significant worldwide concern. This project aims to strengthen insect pest control strategies and improve bio-insecticide use in agriculture through better understanding of the mode of action of Bacillus thuringiensis (Bt) insecticides. It aims to improve their efficacy and evaluate opportunities to develop bio-insecticides based on plant saponins. This will assist in determining the risk of insecticide resistant moths migrating to Australia, and within our borders. This project aims to provide opportunities to improve transgenic Bt-crops and Bt-sprays, provide commercial development of new bio-insecticides, and develop optimal control strategies for major Australian migratory pests.
