摘　　要：通过系统调查,测定了不同茶园昆虫群落结构特征。结果表明,福州茶区节肢动物有85种,其中害虫48种,天敌28种,其它9种。茶园昆虫群落特征参数随时间、茶园类型、茶树空间(部位)等不同而变化。每年以5-6月和9-10月昆虫群落丰富度(S)、样本数(N)、多样性指数(H)和优势度(D)最高。生物农药示范茶园S、H明显高于常规化学防治茶园的,同时,天敌种类及数量分别是化学防治茶园的1.28和2.50倍。Insect community structure in different tea gardens was systematically investigated. The results were as follows ： （ 1 ） eighty five Arthropods species could be found in Fuzhou tea gardens, among which 48 belonged to pests and 28 were natural enemies; （2） the community feature indexes varied with seasons, tea garden type and tea garden space parts ; （3） the highest population richness （ S）, sample number （ N）, diversity index （H） or dominance （D） was found during May to June and September to October, respectively; and （4） compared with those in conventional chemical pesticides treated tea gardens, both S and H were significantly higher in biopesticides treated ones. Meanwhile, the number of natural enemy species as well as their individuals was 1.28 or 2.50 times higher.
