14TSB_ATC_IR Lure-and-kill technology to manage beetle pests (Sitona lineatus and Bruchus rufimanus) of field beans and peas

该项目旨在开发昆虫病原的自动传播，用于生物防治影响产量和质量的两种英国豆类主要害虫Sitona lineatus和Bruchus rufimanus。上世纪80年代初，Rothamsted Research在S的研究中发现了一种对两性都有高度吸引力的红线斑潜蝇的聚集信息素。100871计划正在开发一种结合花卉诱饵的红斑潜蝇的监测诱捕器。该项目将开发一种将昆虫病原真菌与半化学物质结合在一起的“诱杀”陷阱，这种诱杀陷阱是通过静电配制的，以便更好地传递给目标昆虫。这将提供一种有效的、新颖的害虫管理工具。目前，英国豆类种植者还没有可用的生物防治系统来防治这些害虫。还将测试杀虫剂作为杀灭剂的使用情况。该项目将推动农业的可持续集约化，并通过应对豌豆和豆类作物病虫害对质量和生产造成的挑战，同时减少对环境的不利影响，为英国农业技术行业带来经济影响。许多种植者使用5到6种拟除虫菊酯喷雾，以达到对成虫的充分控制，以防止产量损失，随着害虫压力的增加，杀虫剂被证明效果较差。作物保护需要其他办法。该项目开发的“诱杀”系统将为其他害虫和作物提供“概念验证”。

This project seeks to develop autodissemination of entomopathogens for bio-control of Sitona lineatus and Bruchus rufimanus, two major pests of UK legumes that affect yield and quality. An aggregation pheromone for S. lineatus, highly attractive to both sexes, was identified by Rothamsted Research in the early 1980's. A monitoring trap for B. rufimanus, incorporating a floral lure, is under development in TSB project 100871. This project will develop a 'lure and kill' trap combining entomopathogenic fungi with semio-chemicals, formulated electrostatically to enable better delivery to target insects. This will provide an effective and novel pest management tool. There is currently no bio-control system available to UK pulse growers for these pests. Use of insecticide as a killing agent will also be tested. The project will advance sustainable intensification of agriculture and deliver economic impact for the UK Agri-Tech industry by tackling the challenge to quality and production caused by insect pests of pea and bean crops whilst reducing adverse impacts on the environment. Many growers apply 5 to 6 pyrethroid sprays to achieve sufficient control of adult Sitona lineatus to prevent yield loss, and as pest pressure increases, insecticides prove less effective. Alternative approaches for crop protection are needed. The 'lure-and-kill' system developed by the project will provide 'proof of concept' for other pests and crops.
