The results showed that at the beginning stage of being attacked by Chinesis white pine beetle and their symbiotic blue-stain fungus, PAL, PPO, SOD activities and MDA content significantly increased in the phloem of P. armandi, and decreased with the increase of the number of D. armandi and the attacking on the xylem and phloem of P. armandi from blue-stain fungus, then reached the minimum level in withering stage of P. armandi. But the contents of nutrition materials in the phloem, such as water, protein, glucide, fat, amylum and so on, declined with the infestation of D. armandi and symbiotic fungus. In summary, the resistance of physiology and biochemistry in the phloem of P.
