Abstract: In order to promote more effective pest control in tea plantations, we examined the effects of web spider communities in terms of species composition, structure and diversity in tea plantations subjected to different production management. Sampling was collected from tea plantations with low-carbon management (DT) and routine management (CG). The results showed that: Web spiders that were collected belonged to 5 families and 11 species, and Neoscona polyspinipes was the dominant species. The community structure in plantation DT was significantly richer than in plantation CG, with 2.67-fold and 0.68-fold the species and individual numbers, respectively. In addition, the diversity index, during summer-autumn and winter-spring, increased by 1.39-fold and 1.04-fold, respectively, in plantation DT compared with plantation CG, and had a much higher evenness index，and lower dominance index. Principal component analysis showed that plantation DT contained significantly distributed more community orientation offsets to the number of web spiders of Argyrodes argentatus, Itatsina praticola, Neoscona polyspinipes, Neriene cavaleriei, and Achaearanea tepidariorum. Therefore, low- carbon management, a rich habitat structure of plants, and less human interference were all conducive to the protection of web spider species diversity.
