| Abstract: | Spatial niche investigation was carried out on the larva of Anopophora glabripennis occurred in pillow trees based on the hole density and vertical distribution servey.The results showed that it maily damaged the trees with the diameter of breast height(DBH) 11~21 cm,it was concentrated in the trunk below 1 m and over 2 m,the DBH of trees which were damaged was over 5 cm.The results of this study is helpful for the understanding the taxis of A.glabripennis larvae on the host and seleting bahevior to provide theoretical basis for the control of this pest. |
