Abstract: In order to clarify the diversity, dominant species and temporal pattern of insect community in tea gardens, the community characteristics of main pests and natural enemies in typical tea gardens in Shandong Province were studied. The classification and statistics of pests and natural enemies were recorded by visual method, yellow plate method, net scanning method and indoor observation method. A total of 27 species of pests (including mites) and 15 species of natural enemies (including spiders) were found. The main dominant pests in tea gardens were Aleurocanthus spiniferus, Matsumurasca onukii, Toxoptera aurantii, Apolygus lucorμm and Scirtothrips dorsalis. The main dominant natural enemies were Eretmocerus sp., Aphid flies, ladybirds, green lacewings and spiders. Before overwintering, the species abundance and evenness were high in tea gardens, and the community diversity also maintained a high level. During overwintering, the ecological dominance increased rapidly and the community diversity decreased, indicating that the main factor affecting the community dynamics in tea gardens was temperature. The temporal patterns of the main insect pest and natural enemy communities were divided into four stages by using the optimal sorting method. In the first period, from 9th June to 17th July, the dominant pests were A. spiniferus and T. aurantia. In the second period, from 25th July to 12nd September, the dominant pests were A. spiniferus and M. onukii. In the third period, from 20th September to 17th October, the dominant pests were S. dorsalis, A. spiniferus and M. onukii. In the fourth period, from 27th October to 23rd December, the dominant pests were M. onukii and A. lucorμm. The results laid a foundation for guiding the precise prevention and control in tea gardens.
