Through systematic investigation of the pests and natural enemies in the tea plantation, it is clear that the main pests in the tea plantation are green leafhopper, yellow thrips and tea aphid. The dominant degree index of false leafhopper was the highest, reaching 0 郾 5380 ~ 0 郾 9407; the main natural enemies were spiders, and its dominance index reached 0 郾 7505 ~ 0 郾 9508.
