【摘要】 通过对稻田蜘蛛优势种和目标害虫的时间生态位的研究 ,发现害虫生态位宽度值的大小影响蜘蛛的生态位宽度值 ,蜘蛛对目标害虫具有跟随现象。晚稻田蛛虫的生态位宽度值及蛛虫生态位重叠指数值均大于早稻田蛛虫的生态位宽度值和生态位重叠指数值更多还原

【Abstract】 In this article, results of reasearch on the time niche of dominant spiders and their objective pests (such as rice planthopper and leafhopper) indicates that the increases or decreases of the niche breadth value of spiders followed as that of the pests. That confirms in a further way the strong interaction relationshop of spiders and objective pests. The index of niche breadth or niche overlap of spiders in the late rice field is bigger than that of the spiders in the early rice field.更多还原
