Abstract: An investigation was made on the diversities of arthropod community, pest sub-community, and natural enemy sub-community in the mono-cultured and wheat-intercropped jujube orchards with integrated pest management (IPM) and conventional management (CM) in Taigu area of Shanxi Province. The results indicated that there were significant differences (P<0.05) in the diversity indices of the community and sub-communities among these four treatments at different stages of jujube tree growth. The F-test indicated that wheat-jujube intercropping combined with IPM was the main factor affecting the diversity indices of arthropod community, pest sub-community and natural enemy sub-community in jujube orchard ecosystem.
