Abstract:
[Objectives]  To investigate the diversity and dominant species of rice field spiders in Guizhou, and thereby provide a foundation for using rice field spiders to control rice pests. [Methods]  A five-point sampling method, based on the investigation and identification of spider diversity during the tillering and filling stages of rice, was implemented in Bingmei town, Qiandongnan prefecture (A), Fengcheng town, Qiandongnan prefecture (B), Guancang town, Zunyi city (C), Maojian town, Qiannan prefecture (D), Hefeng township, Guiyang city (E), Shuangbao town, Anshun city (F), and Xinmin town, Panzhou city (G). The diversity, dominance, uniformity and similarity of spiders at each location was then comparedand analyzed. [Results]  A total of 6 856 spider specimens were collected, belonging to 111 species of 51 genera and 13 families. The dominant families were the Lycosidae and Tetragnathidae, and the dominant species  were Pirata subpiraticus, Tetragnatha mandibulata, Tetragnatha praedonia, Tetragnatha   nitens, Tetragnatha maxillosa, Pardosa pseudoannulata, Lycosa labialis, Araliape bruennichia, Hahnia corticicola, Mendoza canestrinii, and Oxyopes forcipiformis. The diversity of spider communities in the different locations can be ranked on the basis of the Shannon Wiener diversity index as follows; C>B>G>D>A>F>E, on the basis of the Margalef richness index as; C>B>E>D>F>A>G>F, Pielou uniformity index as C>B>F>G>D=A>E, and on the basis of the Simpson dominance index as E>D=F=A>G>B>C. The similarity and cluster analysis of spider communities in different locations showed that the similarity between two spider communities in rice fields was moderately dissimilar, Among them, Fengcheng Town (B) and Guancang Town (C) have the highest similarity. [Conclusion]  Guizhou rice field spider communities are rich in species and the dominant species differ in in different localities and times of year.
