Development of integrated strategies to control cabbage root fly on radish

本项目的目的是制定一个综合控制策略，以白菜根蝇（CRF）的萝卜。G的营销用品。65%的萝卜销往英国市场，被迫依靠常规应用毒死蜱（一种有机磷杀虫剂）来控制CRF。这种杀虫剂有许多不良特性。毒死蜱很少100%有效，过度依赖一种治疗方法是有风险的。我们将调查可能具有商业应用的IPM策略的所有潜在组成部分，包括文化，物理，生物和杀虫控制。该战略的发展将是在景观规模和萝卜生产周期的要求和有关苍蝇的知识为基础。这包括沃里克大学开发的物候模型。该项目计划如下：1）审查作物管理和损害程度的历史数据，并使用物候模型将其与白菜根蝇生命周期联系起来; 2）审查IPM战略的潜在组成部分; 3）设计和实施实验（实地规模和更小规模），以评价各个组成部分; 4）设计和实施试验，以评估最有前途的组成部分，结合制定一项战略; 5）在商业背景下评估IPM战略6）总结和传播信息。该项目将评估一些控制方法和技术，其中一些本身就是创新的。关键的创新将是为快速生长的块根作物制定IPM战略，这种作物生长到高规格，这是基于对目标害虫的生物学和行为的正确理解。

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.
