Plants are in a constant battle with insect pests and there is an increasing reliance on chemical inputs for control. However there are incoming bans on some pesticides, and new approaches are required for pest management. The aim of this project is to develop a new strategy which exploits the dependence of herbivorous insects on phytosterols. Here, we will apply the latest genomics technologies in plants to produce non-utilizable sterols which will not support insect growth and reproduction, but will still allow the plant to function normally. We will demonstrate this in the important crop canola. Translation of this knowledge will support breeding for crop resilience, leading to durable resistance and more sustainable crop production.

植物与害虫不断抗争，并且越来越多地依赖用于控制的化学输入。但是，在某些农药上有一些传入的禁令，害虫管理需要新的方法。该项目的目的是制定一种新的策略，以利用草食昆虫对植物固醇的依赖性。在这里，我们将在植物中应用最新的基因组技术来产生不利用的固醇，这些固醇将不支持昆虫的生长和繁殖，但仍会允许植物正常发挥作用。我们将在重要的农作物中证明这一点。这种知识的翻译将支持繁殖作物的弹性，从而导致耐用的抵抗力和更可持续的作物生产。
