大豆害虫点蜂缘蝽研究进展

Research progress on soybean stink bug (Riptortus pedestris)

大豆“症青”现象是黄淮海流域大豆生产上亟待解决的重要问题。最新研究发现,“症青”现象与点蜂缘蝽的发生为害有着密不可分的联系。点蜂缘蝽是一种分布广泛的多食性害虫,近年来,该害虫持续发生并呈蔓延趋势,对我国大豆生产造成严重威胁。本文着重介绍了该虫的分布与寄主、为害特点、生物学特性、环境因子的影响、综合防治方法,为深入分析大豆“症青”现象形成机制、开展大豆害虫点蜂缘蝽综合治理研究以及相关政策制定等提供有益的参考。

The staygreen syndrome in soybean has become a major issue to be solved in Huang-Huai-Hai riv er basin.According to recent researches,the soybean stink bug(Riptortus pedestris)was closely related to the stay green syndrome due to its severely damage on soybean.R.pedestris is a widely distributed polyphagous pest with sucking mouth parts.In recent years,this pest continued to occur and tends to spread,which posed a serious threat to soybean production in China.This paper emphatically introduced the distribution and host,damage characteris tics,biological characteristics,environmental factors and integrated control methods.It could provide information for further research staygreen syndrome in soybean,and research on integrated management of the soybean bug and formulation of relevant policies.
