摘　　要：广西是我国八角主产区,为了解为害八角的有害生物主要种类及其为害情况,为生产防控提供参考,2018—2021年笔者在广西八角产区开展了实地调查研究。结果表明:为害广西八角的主要有害生物有30种,其中病害6种,害虫18种,有害植物5种,害鼠1种。当前对八角为害较严重且对生产影响最大的种类是八角尺蠖(Dilophodes elegans subsp.sinica)、八角叶甲(Oides duporti)和八角炭疽病(Colletotrichum horii)。茶堆沙蛀蛾、矢尖蚧、煤烟病、中华简管蓟马和野葛等在一些区域亦出现偏重发生的情况。Star Anise(Illicium verum)is a characteristic economic tree species in Guangxi.To understand the main species of pest of I.verum and the dynamic of their damage,and to provide references for the prevention and control,we have carried out field investigations and studies in Guangxi in recent years.The results showed that there were 30 kinds of main pests in the I.verum forest in Guangxi,including six types of diseases,18 species of insect pests,five types of harmful plants,and one type of rodent.At present,the species with the most serious damage and the greatest impact on the production of I.verum are Dilophoders elegans sinica,Oides duporti,and Colletotrichum horii.Linoclostis gonatias,Unaspis yanonensis,Meliola sp,Haplothrips chinensis,and Pueraria lobata in some areas also heavily occurred.
