摘要: 在农业生态系统中,弹尾虫作为天敌的替代食物,起着间接控制害虫种群的作用。2006年3月至2008年4月(不包含2008年3月),在武夷山星村镇设置了4种不同生境的茶园,分别对其茶冠层和凋落层进行调查分析。在茶冠层,套种百喜草、套种圆叶决明和不除草茶园弹尾虫的物种丰富度(S),套种圆叶决明和不除草茶园弹尾虫的Shannon-Wiener指数(H′),都显著高于除草茶园;套种圆叶决明和不除草茶园弹尾虫的物种丰盛度(N)显著高于套种百喜草茶园。在凋落层,套种百喜草、套种圆叶决明和不除草茶园弹尾虫的SN和绝对丰盛度($\bar{n}$)均显著高于除草茶园,套种百喜草和不除草茶园弹尾虫的有效多样性指数(eH′)显著高于套种圆叶决明茶园。4种不同生境茶园对茶冠层弹尾虫的eH′、均匀性指数(E)和$\bar{n}$及对凋落层弹尾虫的H′E均无显著影响。4种不同生境茶园茶冠层或凋落层的弹尾虫群落相似程度很高。由此可见,合理进行套种,有利于提高茶园生境的多样化,强化中性昆虫在害虫综合治理中的作用。

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.
