摘要
通过采用聚集度指标的方法,在晚稻不同发育期,对稻田蜘蛛及目标害虫飞虱和叶蝉的内分布型进行了系统研究,测定结果表明其内分布型随水稻发育期的变更而变化,为害虫综合防治策略的制定提供依据。
This article dealed with the internal distribution patterns of paddyfield dominant spiders and objective pests(rice planthopper and rice leafhopper) in different development period of lately rice by means of several indexes of aggregation , the results showed that their internal distribution changed with the development period of rice. This result provide basis for strategies of IPM.
