OSR is the second largest UK crop after cereals, but is under significant threat due to the withdrawal of the major conventionalpesticides previously used to control pests such as cabbage stem flea beetle and slugs. The use of volatilesemiochemicals (behaviour-modifying 'information signals' such as pheromones) to lure pests away from a crop is apowerful strategy for crop protection; it can allow effective pest control without causing environmental harm orgenerating unwanted residues on the crop itself. Over the course of this PhD project you will develop "push-pull" strategies for OSR protection, whereby repellentsemiochemicals placed within or near the crop are used in combination with attractant semiochemicals placed as lures orwithin trap crops at a more remote location. This will involve laboratory studies with the pests themselves,determination of the most effective blends and formulations of semiochemical compounds and field trials to determinetheir effectiveness for OSR protection - and any negative effects on non-target/beneficial organisms - under real-worldconditions. You will develop skills and experience in invertebrate rearing, handling and taxonomy, plant growth studies,behavioural bioassays, invertebrate electrophysiology, analytical chemistry, semiochemical formulation and conductingfield trials (design and assessment methods). The outputs of this work will have the potential for substantial economic and environmental impact, and contribute tothe United Nations Sustainable Development Goals of food security and protecting the environment.

OSR是仅次于谷物的英国第二大农作物，但由于先前用于控制诸如卷心菜茎跳蚤甲虫和sl虫等害虫的主要常规药物的撤离，因此受到重大威胁。使用挥发性化学物质（诸如信息素的行为修改“信息信号”）将害虫驱逐出作作物的危险是造成农作物保护的策略；它可以允许有效的害虫控制，而不会造成农作物本身上有害残留物的环境伤害。在这个博士学位项目的过程中，您将制定“推动”策略以保护OSR保护，其中将驱虫剂与耕作物内或附近的驱虫剂结合使用，将其与吸引人的半化学物质结合使用，因为诱饵或诱饵在更偏远的位置上。这将涉及害虫本身的实验室研究，确定半化学化合物和现场试验的最有效的混合和配方，以确定OSR保护的有效性 - 以及对非目标/有益生物的任何负面影响 - 在现实世界中。您将在无脊椎动物饲养，处理和分类法，植物生长研究，行为生物测定，无脊椎动物电生理学，分析化学，半化学配方和导电端口试验（设计和评估方法）方面发展技能和经验。 这项工作的产出将有可能产生重大的经济和环境影响，并为联合国提供粮食安全的可持续发展目标和保护环境。
