The litters and soil physical characteristics of the forest site damaged to certain extents by Hylobitelus xiaoi were compared and analyzed. The results showed that the thickness of litterfall had the most effects on the damage of H. xiaoi, followed by the dry weight of litterfall and the soil weight, and the moisture content rate and water absorbing rate of litterfall had the least effects. That meant that the H. xiaoi damaged more heavily at the sites with thicker litterfall layers, more litterfall amounts and higher soil moisture content. Single factor analysis indicated that the thickness and dry weight of litterfall and soil moisture content were obviously correlated with the rate of insect-attacked tree. The rate of insect-attacked tree in Pinus taeda and P. massoniana plantations were significantly lower than that in P. elliottii plantations. Compared with no-attacked forest site, the insect-attacked sites had higher soil moisture, better water-holding capacity, higher porosity and less gravels.
