The occurrence area and extent of injury of Alcidodes juglans Chao were investigated in this paper. Then the author observed the biological characteristics, developed the control test and risk assessment. The Alcidodes juglans Chao happens 1 generation per year in Bijie Prefecture, and lives through the winter in the forms of imagoes. The attack rate in the occurrence area was from 40.5 to 100%, the killing rate of gains was between 5.2% and 98.4%. Through the risk assessment, the results showed that the Alcidodes juglans Chao is the moderate dangerous pest in forestry territo- ry. It threatened directly the development of the main economic trees （ Juglans regia）.
