The insect resistant factors such as salicylic acid,jasmonic acid,tea polyphenol,caffeine and free amino acid in tea tree germplasm resources of Qianxinan Prefecture were analyzed.The results showed that the content of jasmonic acid was negatively correlated with the number of insects,caffeine was not significantly correlated with the number of insects,tea polyphenols were not significantly correlated with the number of insects,salicylic acid was not significantly correlated with the number of insects,and free amino acids were positively correlated with the number of insects.The occurrence of insect pests in the germplasm resources of an-cient tea trees in Pu'an County was lower than that in Xingyi County,which may be related to the high content of jasmonic acid in the germplasm resources of Pu'an County.In future work,the level of jasmonic acid content can be used as an important reference index for breeding insect-resistant varieties.
