不同品种茶园害虫及天敌群落多样性研究

Diversity of Pest Insect and Natural Enemy Communities in Tea Gardens of Different Varieties

通过对不同品种茶园(巴渝特早、福鼎大白茶、川茶群体种)害虫群落结构及天敌种类进行一年的系统调查,结果表明:茶园中害虫及天敌共有2纲,20目,41科;其优势种群基本相似,主要是同翅目和蜘蛛目;川茶群体种茶园的物种丰富度指数、多样性指数、均匀度指数均高于其他两个品种茶园,且3个品种茶园的害虫和天敌种类具有高度相似性.

Pest insect and natural enemy communities in tea gardens of different varieties（Chuanyu Tezao,FudingDabaicha and Sichuan tea group） were systematically investigated in a survey lasting for years.Forty-one families of pest insects and their natural enemies,belonging to 2 classes and 20 orders,were recorded,Homoptera and Araneida insects being the dominant species.Species richness index,diversity index and evenness index in the tea garden of Sichuan tea group were higher than in the tea gardens of the other two varieties.The pest and natural enemy communities were highly similar in all the three tea gardens.
