| 摘 要： | 对4种不同类型生态茶园中昆虫群落进行调查,共发现茶树害虫50种,天敌45种;生态茶园与纯茶园相比,其昆虫群落丰富度、多样性指数、均匀度指数较高,而优势度指数较低;昆虫群落多样性为梨茶间作>林窗式茶园>杉茶间作>纯茶园。茶园物种的多样性与它的稳定性紧密相关,多样性越强,其稳定性越好,害虫大发生的几率较小。

| Abstract: | Insect communities in tea gardens of 4 different types were systematically investigated by 1-month interval in one year.Fifty species of insect pests on tea plants and 40 species of natural enemies were investigated.The species and individuals of pests were distributed mostly in pure tea gardens.As for natural enemies,they were mostly distributed in tea gardens with pine trees surrounded.The diversity of insect communities in the gardens increased in sequence as follows: pear-tea intercropping>tea garden surrounded with pine trees>fir-tea intercropping>pure tea garden. |
