| 摘 要： | 稻绿椿[Nezara viridula(L.))是川西平原的重要害虫,可危害水稻、豆类等70余种植物。在川西平原一年发生三代,世代重叠,以三代及部分二代成虫,主要在草房上群集越冬,翌年3月下旬至4月上旬迁飞至田间危害活动,以越冬代和第二代成虫及第三代若虫分别危害早玉米及晚稻,迟熟黄豆及扁豆。本文报道了此虫的生活年史,各期习性,各虫态和全世代的发育起点温度和有效积温,并研究分析了耕作制及其他环境因素对发生危害的关系。

| Abstract: | This paper reports an attempt to use fuzzy mathematics as a tool for forecasting the regional population fluctuations of yellow rice borer for moderately long term in Ji-an,Jiangxi,by selecting the forecasting fac-tors conventionally,and applying a number of techniques such as multi-factorial evaluations,fuzzy relation equations and fuzzy preference ratio. The procedures and results are given. |
