[Objectives]  To investigate the population dynamics of Caloptilia theivora and its natural enemies in order to provide a scientific basis for comprehensive control of C. theivora on the Wuniuzao and Baihaozao tea varieties. [Methods]  We used grey correlation analysis and semivariant function theory to model the ecological niches of C. theivora and its natural enemies. We standardized the above results by dividing the correlation and similarity coefficients by the maximum value of each parameter, thereby obtaining a quotient close to the index. Based on this analysis, annual differences between the two tea varieties were analyzed. [Results]  In 2015, the four natural enemies most closely associated with C. theivora on the Wuniuzao tea variety were Clubiona japonicola Boes. et Str, Tetragnatha maxillosa, Oxyopes sertatus L. Koch and Neoscona theisi. The three natural enemies most closely associated with C. theivora on the Baihaozao tea variety were C. japonicola, Tetragnatha maxillosa，Neoscona theisi and O. sertatus. The difference in ranking of these eight predators between the two tea varieties was 62.5%. In 2016, the four natural enemies most closely associated with C. theivora on the Baihaozao tea variety were O. sertatus, C. japonicola, N. theisi and T. maxillosa. The four natural enemies most closely associated with C. theivora on the Wuniuzao tea variety were N. theisi, Erigonidium graminicolum, T. maxillosa and C. japonicola. The difference in ranking between the two tea varieties was 87.5% and the difference in ranking among natural enemies was 75%. Comparing 2015 and 2016, the four highest ranked natural enemies were T. maxillosa, C. japonicola N. theisi and O. sertatus on the Wuniuzao tea variety, and the annual difference in ranking among different natural enemies was 87.5%. The four most important natural enemies in both years on the Baihaozao tea variety were T. maxillosa, C. japonicola, N. theisi and O. sertatus, the proportion of different natural enemies was 75%. The average difference in ranking among natural enemies in the two tea varieties was 81.25%. The four spider species most closely associated with C. theivora in abundance, time and space were C. japonicola, N. theisi, T. maxillosa and O. sertatus. [Conclusion]  Ranking of natural enemies of C. theivora was more affected by tea variety than year.
