Community diversity was subsequently analyzed. A total of 20 827 acridoids were collected, belonging to six families, 13 genera and 15 species. Arcypteridae was the dominant family, with Euchorthippus unicolor and E. vittatus as the dominant species. Diversity analysis revealed that the Simpson diversity index (0.67), Shannon-Wiener diversity index (1.29), and Margalef richness index (1.24) for typical grassland were all significantly higher than those for forest understory grassland (0.57, 1.00, 0.95, respectively) and field-margin grassland (0.61, 1.03, 1.04, respectively), indicating that vegetation structure, environmental conditions, and anthropogenic disturbances have a combined influence on grasshopper diversity and community structure. Temporally, the number of species (July 2023: 4.45 species; August: 4.01 species; September: 2.86 species; July 2024: 4.88 species; August: 4.26 species; September: 3.02 species), abundance (July 2023: 29.17 individuals; August: 19.57 individuals; September: 8.80 individuals; July 2024: 33.92 individuals; August: 22.11 individuals; September: 8.80 individuals), and all diversity indices were highest in July, followed by August, and lowest in September, reflecting the regular seasonal succession of the grasshopper community structure. These findings indicate that the community structure and diversity of grasshoppers in Kangping County are jointly influenced by seasonal variation and habitat type. Given its location within the ecological transition zone at the southern margin of the Horqin Sandy Land, longterm monitoring of insect diversity in Kangping County is essential for understanding species composition and community dynamics in transitional ecosystems. keywords:grassland  Acridoidea  community structure  biodiversity  spatiotemporal dynamics View Full Text  View/Add Comment  Download reader
