山西省棉田昆虫群落的时间动态研究

Time dynamics of insect community in cotton field of Shanxi Province

  • 摘要: 以丰富度、多样性指数、昆虫总个体数、种间相遇机率和均匀度为数据指标,采用系统聚类法分 析了山西省棉田昆虫群落的时间动态,结合棉株的生理状况将其划分为4个阶段,并探讨了各阶段的害虫管理对策 。

     

    Abstract: Hierarchical cluster was employed to analyse the time dynamics of insect community in cotton field of Shanxi,based on the richness,diversity index,total individual number,PIE,evenness. The result show that its time pattern could be divided into four stages.Considering the development condition of cotton plant,the integrated pest management(IPM) strategies on every period were also explored.
