Abstract:【Objective】To clarify the relationships of Stephanitis chinensis and Lygus lucorum with natural enemies in ‘Baihaozao’ tea garden.【Method】The population numbers of pests and natural enemies were investigated. The numerical, temporal and spatial relationships of natural enemies with S. chinensis and L. lucorum were studied using grey relational analysis and niche analysis.【Result】The major natural enemies of pests in ‘Baihaozao’ tea garden included Tetragnatha squamata, Tetragnatha maxillosa, Theridion octomaculatum, Clubiona japonicola, Neoscona theisi, Misumenops tricuspidatus, Erigonidium graminicolum and Oxyopes sertatus. The top four enemies showing close relationships with S. chinensis were C. japonicola, O. sertatus, T. maxillosa and N. theisi in 2015, while C. japonicola, O. sertatus, E. graminicolum and N. theisi in 2016. The natural enemies ranking the first, second and fourth were the same in two years. The differential degree between the ranks of natural enemies in two years was 62.5%. The top four enemies showing close relationships with L. lucorum were T. maxillosa, M. tricuspidatus, T. squamata and T. octomaculatum in 2015, while M. tricuspidatus, N. theisi, T. maxillosa and E. graminicolum in 2016. Two of the four major enemies were the same in two years, but the order was different. The differential degree between the ranks of natural enemies in two years was 87.5%.【Conclusion】The changes in ranks of natural enemies possibly depend on the ratio of the number of pests to their natural enemies.
