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是英国仅次于谷物的第二大作物，但由于以前用于控制白菜茎跳蚤甲虫和蛞蝓等害虫的主要常规杀虫剂的退出，OSR受到重大威胁。使用挥发性化学物质（行为改变的“信息信号”，如信息素）引诱害虫远离作物是作物保护的一个强有力的策略;它可以有效地控制害虫，而不会造成环境危害或在作物本身产生不必要的残留物。在这个博士项目的过程中，您将开发OSR保护的“推拉”策略，即放置在作物内或附近的驱避剂化学信息素与引诱剂化学信息素结合使用，作为诱饵或在更偏远的位置放置在陷阱作物内。这将涉及对害虫本身的实验室研究，确定最有效的化学信息素化合物的混合物和配方，以及实地试验，以确定它们在实际条件下对OSR保护的有效性-以及对非目标/有益生物的任何负面影响。您将在无脊椎动物饲养，处理和分类，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，化学信息素配方和进行田间试验（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，并有助于实现联合国粮食安全和保护环境的可持续发展目标。
