This PhD project aims to create the underlying knowledge required to help develop new more environmentally-friendly approaches to controlling the key insect pest on rapeseed, the cabbage stem flea beetle. Flea beetles had previously been effectively controlled by neonicotinoid seed treatments, but the current usage ban in Europe based on toxic effects on bee populations mean that we need new and more specific approaches to protecting rapeseed crops from flea beetle damage. Central to this effort is the need to understand the molecular genetics of the interaction between flea beetles and the rapeseed crop in more detail. In this project you will develop methods for analysing the molecular events that enable flea beetles to overcome rapeseed plant defences and successfully attack the crop. You will use new genomic tools to understand plant responses to insect feeding, and use modern breeding techniques to identity and characterise sources of resistance to flea beetle attack using exotic brassica germplasm collections from our commercial partner. The project will run closely with the rapeseed breeding company Limagrain and will include opportunities to take secondments at Limagrain and to exploit their field trials programme and genetic tools for this project.

这个博士项目旨在创造必要的基础知识，以帮助开发更环保的新方法来控制油菜籽上的关键害虫--甘蓝茎跳甲。以前，通过新烟碱类种子处理可以有效地控制跳甲，但目前欧洲基于对蜜蜂种群的有毒影响而禁止使用，这意味着我们需要新的和更具体的方法来保护油菜籽作物免受跳甲的伤害。这项工作的核心是需要更详细地了解跳甲和油菜籽作物之间相互作用的分子遗传学。在本项目中，您将开发分析使跳甲能够克服油菜籽植物防御并成功攻击作物的分子事件的方法。您将使用新的基因组工具来了解植物对昆虫取食的反应，并使用现代育种技术来使用我们商业合作伙伴的外来Brassica种质收集来识别和表征抗蚤甲虫攻击的来源。该项目将与油菜籽育种公司LImagrain密切合作，并将有机会在LImagrain借调，并为该项目利用他们的田间试验方案和遗传工具。
