蚜虫新型预警网络的构建及其绿色防控技术研究

A new aphid-monitoring network system based on suction trapping and development of "green techniques" for aphid management

在公益性行业(农业)科研专项的支持下,项目组在我国大豆和小麦主产区进行了蚜虫监测预警及绿色防控技术的研究。构建了基于吸虫塔的蚜虫监测预警网络系统,在蚜虫基础生物学研究、天敌资源普查及其控蚜作用研究的基础上,研发了多项以生物防治为主体的蚜虫绿色防控技术,包括天敌人工助迁、人工饲养天敌释放、作物邻间作措施、物理防控、隐蔽性施药等。相关技术措施在我国的东北、华北等大豆蚜、麦蚜为害严重的大豆产区和小麦主产区共建立了4个规模较大的试验示范区,取得了较好的综合效益。

Supported by the National Special Fund for Agro-scientific Research in the Public Interest,a new aphid-monitor network system based on suction trapping has been constructed around the main production areas of soybean and wheat in China and several green techniques developed to control aphid infestations in soybean and wheat crops.Some basic biological aspects of the soybean aphid Aphis glycines Matsumura were clarified and the potential of its natural enemies to suppress aphid populations was investigated.The green techniques developed to control aphids are based on biological control principles and include artificially moving natural enemies to crop fields,artificial mass rearing lady beetles to control aphids,intercropping or adjacent cropping,measurements of physical control and applying chemicals in concealment.All these techniques had demonstrated benefits in a total of 4 demonstration plots where aphids had previously been causing severe crop losses.
