Abstract：Twenty Chinese chives cultivars that showed different resistance to Bradysia odoriphage were selected to study the correlations between the pest resistance（based on 3 pest resistant index: pest density，percentage of infected plants and leaf suffering index）and the content of several physiological chemical substances，including coarse-fiber，naphtha，soluble sugar，soluble protein，pigment，chlorophl-a and dissociative amino acids．The results showed that the contents of naphths，soluble sugar and dissociative amino acids in the resistant cultivars appeared with lower content than those of the infective ones．But the contents of coarse-fiber，soluble protein，pigment and chlorophl-a in the resistant cultivars showed higher values than the infective ones．The results of correlative analysis showed that the contents of naphtha，soluble protein and dissociative amino acids displayed distinct correlations with the level of pest resistance．And the results of regression analysis also revealed that the content of naphtha might be the most important factor for the pest resistance．
