The species community, species abundance and diversity index were compared and analyzed. The pitfall traps caught a total of 8532 specimens, which were classified to 33 families, 11 orders, 3 classes. The traps in rice paddy collected 5878 individuals, which were from 35 species, 27 families, 8 orders, and among which the species richness index, Shannon-Wiener diversity index and evenness index of ground predators were 1.8779, 0.7297 and 0.2576, respectively. The traps in cotton fields collected 2654 individuals, which were from 35 species, 28 families, 9 orders, and among which the species richness index, Shannon-Wiener diversity index and evenness index of ground predators were 2.4771, 0.8041, and 0.4149, respectively. A total of 5971 individuals of ground predators were collected in the rice-cotton adjacent planting fields, which belong to17 species, 13 families, 3 orders, and 3 classes. The most dominant predator species is the most abundant spiders (Arachnids) and the second dominant predator species is rice field frog Rana limnocharis, while the predatory Coleopteran natural enemies, including ladybugs and ground beetles, are characterized by high species diversity. %U http://www.zgswfz.com.cn/EN/10.16409/j.cnki.2095-039x.2020.01.003
