摘　　要：采用稻草覆盖地表,观察其对甘蓝类蔬菜害虫的控制效果。试验发现,稻草覆盖可增加田间游猎型蜘蛛的数量,且对菜青虫、小菜蛾和甘蓝夜蛾的为害都有一定的控制作用。其中以秋季的控害效果最好。对菜青虫和甘蓝夜蛾幼虫1~6龄幼虫的控害效果最高分别达到84.8%和78.4%,三种害虫的产卵量都有减少。The experiment found that straw covering could increase the number of wandering-and-hunting spiders in the field,and thus had a certain control effect on the damage of cabbage caterpillar,diamondback caterpillar and mamestra brassicae.The best control effect was in autumn.The control effect on1-6larvae of Cabbage caterpillar and mamestra brassicae was up to84.8%and78.4%respectively.The numbers of egg-laying by the three kinds of pests had decreased.
