| 摘 要： | 为了系统明确湖南地区油茶害虫的主要种类，以2011年6月—2013年8月湖南省油茶害虫调查数据为基础，运用多指标综合评估分析法、害虫风险指数加权法与经验公式法，从害虫分布区域、危害程度、生物学特性、生态学特性和防治处理难度5个方面（包括16个风险因子）对危害油茶的172种害虫的综合危害程度进行了评估。将湖南省油茶害虫划分为4个级别，茶籽象甲Curculio chinensis、黑跗眼天牛Bacchisa atritarsis、油茶毒蛾Euproctis pseudoconspersa为危害油茶频发性成灾的害虫；茶角胸叶甲Basilepta melanopus、油茶织蛾Casmara patrona、油茶尺蠖Biston marginata、油茶叶蜂Caliron camellia、桃蛀螟Conogethes punctiferalis、广西灰象Sympiezomias citri、油茶堆砂蛀蛾Linoclostis gonatias、油茶金花虫Colaspoides opaca、茶长卷叶蛾Homona magnanima为高危害虫（偶发性成灾害虫）；并列出了14种中危性害虫，其他均为低危或无危害虫。根据害虫的危险性等级，对油茶害虫的防治提出了相关建议。

The Risking and Classification Analysis of Oil-Tea Pests in Hunan |
| |
| Abstract: | In order to figure out main pests of Camellia oleifera in Hunan, the risk analysis of oil-tea pest was conducted by the methods including multi-criteria evaluation, risk assessment indices and experience formula. According to integrated information of 172 species, five fields with 16 risk factors, i.e., the distribution area of pest, harmful levels, biological characteristics, ecological characteristics and the difficulty of prevention control were considered in the risk analysis. The analysis results showed that oil-tea pests in Hunan Province were ranked four risking classifications. Curculio chinensis, Bacchisa atritarsis, Euproctis pseudoconspersa were included in the first classification, which were the frequent disaster pests. And Basilepta melanopus, Casmara patrona, Biston marginata, Caliron camellia, Conogethes punctiferalis, Sympiezomias citri, Linoclostis gonatias, Colaspoides opaca, Homona magnanima were ranked in the second classification, which were the incidental disaster pests. Other species were general pests or no damaged to Camellia oleifera. Meanwhile, control methods of pests belonging to different classifications were discussed. |
