湖南兰岭茶厂茶园主要害虫为假眼小绿叶蝉、灰尺蠖、大尺蠖 (油桐尺蠖 )、茶毛虫、丽绿刺蛾、茶弈刺蛾、角胸叶甲 ;害虫主要天敌有茶园蜘蛛、瓢虫、草蛉、步甲、螳螂、绒茧蜂、黑卵蜂。三种不同管理类型茶园害虫——天敌群落多样性 ,以生态调控园的多样性指数、均匀度指数最高 ,自然控制园多样性指数与生态调控园近似 ,但均匀度指数低于生态调控园。以化防管理园的多样性指数、均匀度指数最低 ,而优势度指数最高。说明喷用化学农药治虫、防病、除草对茶园害虫、天敌群落结构破坏性极大。
The main pests of tea plantation in LanLan tea factory in Hunan Province are the green leafhoppers, the gray scales, the large scales (tung tree), the tea caterpillars, the green moths, the tea ghost moths, , Ladybugs, hogweed, carabiner, mantis, velvet bee, black egg. The diversity of tea plantation pests and natural enemies in three different management types is the highest. The diversity index and evenness index of the ecological control garden are the highest. The natural control garden diversity index is similar to the ecological control garden, but the evenness index is lower than the ecological control garden. In order to prevent and control Park diversity index, evenness index lowest, and dominance index highest. Description spraying chemical pesticides pest control, disease prevention, weeding on tea plant pests, natural enemy community structure is extremely destructive.
