摘要
通过室内试验和田间系统调查,得出:(1)3种蜘蛛对食饵的捕食量随着食饵密度的增加而增加,成蛛捕食量大于若蛛;(2)田间蜘蛛种群变化随着害虫密度增减而增减;(3)合理用药,保护田埂杂草,田埂种豆是保护蜘蛛的有效措施。
The results of
experiment at laboratory and systematic investigation in the fields showed:(1) the predation
amount of three kinds of spiders increased over the increase of their prey's density,and adult

followed the change of the pests' density in the fields;(3) rationally utilizing insectcide,protecting
weed on fieldbank and planting soybean on embankment were the effective methods in spider
protection.
