摘  要:
Through observation,analysis and measurement,the morphological features of trees effecting the behaviors of longicorns in mixed forests were found out,i.e.,the rough- ness of the tree bark,leaf texture,seize,epidemal hair,gland smoothness,hair of tender branches,hardness etc.Moreover,the selection behaviors of longicorns and population dy- namics were also effected by food characters.
