Abstract: 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 4 generations 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.

Key words: Opogona sacchari, biological properties, integrated control, Zhejiang Province
