| 摘 要： | 通过稻田定点调查，初步鉴定长沙地区稻田有蜘蛛8科28种，其中主要成分依次为狼蛛、皿蛛、球蛛和肖蛸等；蜘蛛群落结构在水稻的不同发育期有明显不同；根据多样性指数（H）、优势度（C）和均匀度（E）的分析，早稻发育前期（5月）蜘蛛群落物种多样性明显小于中期（6月）和后期（7月）。优势种为拟水狼蛛和食虫沟偏蛛，分析了拟水狼蛛和食虫沟瘤蛛及蜘蛛混合种群的消长动态，对优势种蜘蛛与目标害虫的关系进行了初步分析。

| Abstract: | Based on preliminary investigation in fixed position in Changsha,there were more than 28 species of spider in the early rice field,Which belonged to Lycosidae, Linyphiidae, Theridiidae and Tetragnathidae et al .The structure of spider communities in the different development stage were different.According to analysis of Shannon Wiener's species diversity index and Simpson's evenness index,the species diversity in the early stage of rice development were apparently less than that of in the middle and late stage.The dominant were Pirata subpiraticus and Ummeliata insecticeps.The population dynamics of Pirata subpiraticus,Ummeliata insecticeps and mixed population of spiders in the early rice fields were analysed,and a primary study was made on interaction relationship of the dominant paddyfield spider and objective pests. |
