摘　　要：通过野外调查和室内饲养观察,查清了蔗扁蛾在浙江省分布于杭州、温州、嘉兴、衢州、台州、舟山、金华、义乌、永康等46个县市;寄主为巴西木、荷兰铁、海南铁等约22科74种;以幼虫在植株皮层内上下蛀食,危害轻时,局部受损;危害重时,将整段木桩的皮层和木质部全部蛀空,最后整株枯死。摸清了蔗扁蛾在浙江省的生物学特性,一年发生4代,在野外不能越冬,但能在大棚和温室的土壤内以幼虫越冬,交配时间在中午和午夜。通过室内毒力测定筛选出二种低毒化学农药吡虫啉、阿维菌素及生物农药BT用于防治蔗扁蛾,并探讨了综合防治蔗扁蛾的策略。Through the field investigation and the laboratory rearing,we found out Opogona sacchari in Zhejiang Province,located in Hangzhou,Wenzhou,Jiaxing,Quzhou,Taizhou,Zhoushan,Jinhua,Yiwu,Yongkang and other 46 cities and counties; host for Brazil,Holland iron,Hainan iron and other about 22 families and 74 species of plants. The larvae eat up and down within the plant cortex. When the hazard was light,partial of the tree was damaged; while the hazard was heavy,the entire cortex and xylem stakes were all gnawed away,and finally the whole plant died. We also find out Opogona sacchari＇s biological characteristics in Zhejiang Province,which is 4generations a year,couldn＇t pass the winter in the open fields but the larvae could overwinter in the soil of greenhouses,and it mate at noon and afternoon. By indoor toxicological test,we screened out two low-toxic chemical pesticides—imidacloprid,abamectin and one biopesticide—BT to prevent Opogona sacchari. Moreover,this paper discussed the integrated control of Opogona sacchari.
