Clustering analysis and optimal cut-apart of arthropod community in megranate orchard

Abstract

Abstract: Based on the principles of community ecology and by the method of fuzzy clustering,this paper studied the temporal and quantitative dynamics of the arthropod community and sub-community in megranate orchard,aimed to utilize natural enemy resources for pests control.The results showed that both of total community and natural enemy sub-community could be grouped into 4 clusters,and non-natural enemy sub-community could be grouped into 3 clusters.This clustering reflected the complexity of the community structure.The optimal cut-apart could divide the total community and sub-community into 3 stages,i.e.,April-August,September-October,and November.

Key words: Megranate orchard, Arthropod community, Dynamics
