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。
Nezara viridula (L.) is an important pest in the western Sichuan plain and can endanger more than 70 species of plants such as rice and beans. In the western Sichuan Plain, three generations occur each year, the generations overlap, with three generations and some two generations of adults, mainly in the grass cluster cluster wintering, the following year from late March to early April to migrate to the field of hazardous activity, overwintering and second generation adults And the third generation of nymphs, respectively, endanger early corn and late rice, late maturing soybeans and lentils. This article reports the life history of pests, the habits of each stage, the developmental starting point temperature and effective accumulated temperature of each stage and all generations, and studies the relationship between tillage system and other environmental factors.
