勐海茶区不同类型茶园节肢动物群落组成及多样性研究

以云南省勐海县茶叶种植区为研究基地,于2007~2009年分别对樟-茶间作茶园、芒果-茶间作茶园和纯茶园3种不同类型茶园中节肢动物群落多样性进行了系统调查。研究结果表明:勐海茶区共发现节肢动物有17目61科121种,包括有害节肢动物12目41科71种,天敌类群9目20科50种;樟-茶间作茶园与芒果-茶间作茶园中节肢动物群落的Shannon多样性指数、均匀度指数、丰富度指数均高于纯茶园。这表明复合种植能显著提高茶园节肢动物群落的多样性,其结构更合理。

Composition and Diversity of Arthropod Community in Different Types of Tea Plantations in Menghai Tea Area

The diversity of arthropod community was investigated systematically in three tea plantations,including the camphor-tea intercropping plantation,mango-tea intercropping plantation and pure tea plantation in Menghai tea area in Yunnan province during 2007～2009.The results were as follows: There were 121 species arthropods in 17 orders 67 families of insects,including 71 species in 12 orders 41 families of pests and 50 species in 9 orders 20 families of natural enemy insects.The Shannon’s diversity index,the degree of homogeneity index and the degree of richness index of arthropod community in the camphor-tea and mango-tea intercropping plantation both were higher than that of pure tea plantation.It indicated that complex planting could improve diversity of arthropod community in the tea plantations significantly,and the structure was more reasonable.
