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体的自动传播，以生物防治英国豆类的两种主要害虫，影响产量和质量的Sitona lineatus和Bruchus rufimanus。本文报道了一种新的聚体信息素。对两性都有高度吸引力的线纹龙，是在1980年代早期由Rothamsted研究所发现的。B的监控陷阱。在TSB项目100871中，正在开发含有花卉诱饵的rufimanus。该项目将开发一种结合昆虫病原真菌和化学信息素的“引诱和杀死”陷阱，通过静电配制，能够更好地传递给目标昆虫。这将提供一种有效和新颖的害虫管理工具。目前，英国豆类种植者还没有针对这些害虫的生物控制系统。还将测试杀虫剂作为杀灭剂的使用。该项目将推进农业的可持续集约化，并通过应对豌豆和豆类作物虫害对质量和产量造成的挑战，同时减少对环境的不利影响，为英国农业技术产业带来经济影响。许多种植者使用5至6次拟除虫菊酯喷雾剂来充分控制成虫Sitona lineatus，以防止产量损失，随着害虫压力的增加，杀虫剂证明不太有效。需要采取其他办法保护作物。该项目开发的“引诱和杀死”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.
