Preliminary Study on Spider Resources in Shuijiang Nature Reserve of Jiangxi Province

Objective] The aim of the research was to provide the theoretical basis for the biodiversity protection and utilization in Shuijiang nature reserve of Jiangxi province.Method] Field investigation was mainly made in 8 kinds of typical ecotopes at 7 sites in the nature reserve protected area.Spider samples were isolated and extracted from soil,the earth's surface,tree surface,rock surface,water surface and so on by taking the conventional methods including specimen collection(combining fixed-point and random method,trapping and artificial feeding),indoor rearing and in vivo observation,soaking with 75 % alcohol,identification and classification,and so on to gain spider specimens.And they were identified after arrangement and classification.Result] 1887 shares of spider specimens were collected from Shuijiang nature reserve.According to the identification results,they belonged to 111 species,48 genera,14 families.Among them,there were 17 new record spicies in Jiangxi province and 25 undefined species,occupying 15.5 % and 23.6 % resp.Conclusion] It was preliminarily confirmed that there were abundant spider resources in Shuijiang nature reserve of Jiangxi province.
