| Abstract: | The trees of Pinus elliottii may have resistance to the insects of Oracella acuta Ferris and reduce the insect population density after the trees are damaged by the insect.The insect population density in the closed plantation,in the plantation on the slope with less sunlight,at the edge of a plantation,in high elevation plantation and mixed plantation is lower than the population density in the open plantation,the plantation on the slope with more sunlight,in the middle of a plantation,in low elevation plantation and pure plantation respectively. |

| Keywords: | Oracella acuta population density environmental factor |
