Abstract: Collembola is an alternative source of food for natural enemies, a kind of bio-control agent and played an important roles in suppressing pest populations in many agroecosystems. The composition, structure and diversity of the Collembola sampled in the tea canopies or on the ground litters of tea plantations with different habitats on Wuyi Mountains from March 2006 to April 2008 (excluding March 2008) were investigated. In the tea canopies, the species richness (S) of Collembola in the tea plantation intercropped with Paspalum notatum, Cassia rotundifolia or with natural ground cover, and the Shannon-Wiener index (H′) of Collembola in the tea plantation intercropped with C. rotundifolia or with natural ground cover were significantly higher than those on the bare ground. The species abundance (N) of Collembola in the tea plantation intercropped with C. rotundifolia or with natural ground cover was significantly higher than that in the tea plantation intercropped with P. notatum. On the ground litters, the species richness (S), species abundance (N) and absolute abundance ($\bar{n}$) of collembola in the tea plantations intercropped with P. notatum, C. rotundifolia or with natural ground cover were significantly higher than those on the bare ground; the collembola effective diversity index (eH′) in the the tea plantations intercropped with P. notatum or with natural ground cover was significantly higher than that in the the tea plantations intercropped with C. rotundifolia. The effective diversity index (eH′), evenness index (E) and absolute abundance ($\bar{n}$) of collembolan in the tea canopies were no significant difference among crop treatments. It also showed no significant difference in the Shannon-Wiener index (H′) and evenness index (E) on the ground litters. The higher similarity of Collembola population was found within the canopies or the ground litters of the four different tea plantations. These findings suggested that rational intercropping may potentially increase the habitat diversity in tea plantations and strengthen the roles of neutral insects in implementation of integrated pest management (IPM) program in tea plantations.
