研究表明杉木韧皮具树脂道，被天牛蛀伤后泌出的树脂对天牛有杀伤作用，杀伤力的大小与天牛幼虫虫龄有关。初期幼虫最易被树脂胶死，胶死率达４３．５１％，中、后期幼虫的胶死率为４．９２％，初期幼虫的胶死率与泌脂量正相关（ｒ＝０．９６０２）。杉木受害后有较强的愈伤修复能力，能显著减轻天牛危害造成的损失。合理施肥能促进树脂分泌，提高对初期幼虫的胶死率，抚育间伐能显著提高杉木愈伤修复能力。
Studies have shown that Chinese fir resin phloem Road, beetles decoction of the resin secretion of the beetles have a lethal effect, the size of the lethality larvae and pest insects related. The initial larvae were most likely to die of resin glue, the rate of jellosis was 43.51%, the rate of medium and late stage larvae was 4.92%, and the initial larvae ’s rate of jellication was positively correlated with the amount of fat production (r = 0.9602 ). Cunninghamia lanceolata has a strong callus repair ability, can significantly reduce the damage caused by the hordeolus. Rational fertilization can promote the secretion of resin and improve the initial mortality of larvae, thinning can significantly improve Chinese fir callus repair ability.
