摘　　要：针对海南大叶种茶树病虫害研究报道较少的实际,于2019—2021年在海南大叶种茶核心产区五指山市水满乡调查了海南大叶种茶树的病虫害发生种类和发生程度。发现的病害有茶饼病、茶轮斑病、茶炭疽病、茶芽枯病、茶白星病等12种,其中茶饼病、茶轮斑病、茶炭疽病发生普遍且为害严重;发现的害虫有小贯小绿叶蝉、茶角盲蝽、茶潜叶蝇、茶蚜、茶卷叶蛾、茶斑蛾、茶蚕等18种,其中以小贯小绿叶蝉、茶角盲蝽和茶蚕为害严重。调查结果将为进一步开展海南大叶种茶核心产区茶树病虫害防控提供基础数据。Shuiman Township is a major production area for Hainan large-leaf tea(Camellia sinensis var.assamica cv.Hainan.dayezhong).Given the limited research on diseases and pests affecting Hainan large-leaf tea plants,this study investigated the species and severity of diseases and pests on Hainan large-leaf tea trees in Shuiman Township,Wuzhishan City from 2019 to 2021.A total of 12 species of diseases were identified in tea plants including tea blister blight disease,tea gray blight disease,tea anthracnose disease,tea bud blight,and tea white scab disease.Among them,tea blister blight disease,tea gray blight disease,and tea anthracnose disease were prevalent and severe.Furthermore,18 species of insect pests were detected,including Empoasca(Matsumurasca)onukii,Helopeltis sp.,Chlorops theae,Aphis(Toxoptera)aurantii,Homona coffearia,Eterusia aedea,and Andraca bipunctata.Helopeltis sp.,Empoasca onukii,and Andraca bipunctata were identified as significant foliar pests during the research.The results obtained would serve as fundamental data for future prevention and control of tea plant diseases and pests in the main production areas of Hainan large-leaf tea.
