Abstract:
Objective Species and community of the insects found at the tea plantations of different types in Bazhong City were surveyed.
Method Insects were regularly collected in two consecutive years by setting Markov nets at the Daguanliang Organic Tea Garden as well as the conventional plantation of Yuandingzi Tea Garden and another at Nanying Village for morphological identification and diversity analysis.
Result At the Daguanliang Organic Tea Garden, 2373 insect specimens in 2019 and 3641 in 2020 were caught with a total of 113 species of 8 orders and 140 of 12 orders. From the Yuandingzi Tea Garden, 4768 specimens in 2019 and 5699 in 2020 that included 182 species of 9 orders and 196 species of 10 orders, while in the plantation at Nanying Village, 2943 insects in 2019 and 1637 in 2020 that consisted of 151 species in 9 orders and 152 species in 9 orders were gathered. The insects collected at the three sites were mainly Hymenoptera, Diptera, and Hemiptera. However, the plantations varied in the species, population, and indices on diversity, richness, and evenness of dominant insects, as indicated by the catches at the localities.
Conclusion The survey conducted by this study showed a clear picture of the insect species and community at the different types of tea plantations in Bazhong. The information would facilitate further study leading to an improved pest control management for the local tea industry.
