Development of integrated strategies to control cabbage root fly on radish

本项目的目的是开发萝卜白菜根蝇（CRF）的综合防治策略。G's Marketing向英国市场供应约65%的萝卜，并被迫依靠常规使用毒死蜱（一种有机磷杀虫剂）来控制CRF。这种杀虫剂有许多不受欢迎的特性。毒死蜱很少100%有效，过度依赖一种治疗方法是有风险的。我们将调查IPM战略中可能具有商业应用的所有潜在组成部分，包括文化、物理、生物和杀虫控制。该战略的制定将在景观范围内进行，并以萝卜生产周期的要求和有关苍蝇的知识为基础。这包括华威大学开发的物候模型。项目计划如下：1)回顾作物管理和损害水平的历史数据，并使用物候模型将其与白菜根蝇的生命周期联系起来；2)审查IPM战略的潜在组成部分；3)设计和实施实验（现场规模或更小）来评估单个组件；4)设计和实施试验，综合评估最有希望的组成部分，以制定战略；5)在商业环境中评估IPM策略6)总结和传播信息。该项目将评价若干控制方法和技术，其中若干方法和技术本身具有创新性。关键的创新将是发展一种快速生长的根茎作物的IPM战略，在对目标害虫的生物学和行为有充分了解的基础上，种植到高规格。

The aim of this project is to develop an integrated control strategy for the cabbage root fly (CRF) on radish. G's Marketing supplies ca. 65% of all the radish to the UK market and is forced to rely on routine application of chlorpyrifos, an organophosphorus insecticide, to control CRF. This pesticide has a number of undesirable characteristics. Chlorpyrifos is rarely 100% effective and over-reliance on one treatment is risky. We will investigate all potential components of an IPM strategy that may have commercial application, including cultural, physical, biological and insecticidal control. Development of the strategy will be at a landscape scale and underpinned by requirements of the radish production cycle and knowledge about the fly. This includes a phenological model developed at Warwick University. The project plan will be as follows 1) review historical data on crop management and damage levels and use phenological model to link this to the cabbage root fly life cycle; 2) review potential components of an IPM strategy; 3) design and implement experiments (field-scale and smaller) to evaluate individual components; 4) design and implement trials to evaluate the most promising components in combination to develop a strategy; 5) evaluate the IPM strategy in a commercial context 6) summarise and disseminate information. The project will evaluate a number of control methods and techniques, several of which are innovative in themselves. The key innovation will be the development of an IPM strategy for a rapidly-growing root crop, grown to a high specification that is based on a sound understanding of the biology and behaviour of the target pest.
