白蚁危害幼杉严重，在大四方林区4块标准地1994年调查，生长不良株率9—19．5％，死亡株率达14．84—24．10％，幼杉的长势较差。在老木坞林区杉木成林的3块标准地上的3株解析木分析，胸径损失率29．1％，树高生长损失12．7％，材积总生长量损失率为58．3％，每亩损失材积7．527m3。
Termitomyces severely damaged young seedlings, four large areas in the four areas of 1994 standard survey, the poor growth rate of 9-19.5% plants, death rate of 14.84-24.10%, the growth of the inferior seedlings. The three analytical trees on three standard plots of Chinese fir forest in Laokuwu forestry area showed that the DBH loss rate was 29.1%, the tree height growth loss was 12.7%, and the volume loss of total volume growth was 58.3% Mu loss of volume 7.527m3.
