摘要: 在太谷地区枣麦间作与枣单作生态系统中,研究了综合防治与常规防治对枣树不同发育阶段的节肢动物群落、害虫亚群落和天敌亚群落多样性的影响。结果表明:在各个发育阶段,4种不同处理中的枣园节肢动物群落、害虫亚群落和天敌亚群落的多样性指数均存在显著性差异 (P<0.05);通过对影响枣园生态系统3种多样性指数的因子的方差分析表明,枣麦间作和综合防治措施的共同作用是影响枣园生态系统节肢动物群落和天敌亚群落多样性指数的主要因子。

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.
