摘要
通过棉田定点调查,初步鉴定陕西大荔棉田计有蜘蛛8科17种,其中主要成分依次为狼蛛、皿蛛、球蛛、蟹蛛,园蛛和肖蛸等;蜘蛛群落结构在棉花苗期和蕾铃期有明显不同;Shannon-wiener多样性指数,simpson优势度和均匀度等分析,棉花苗期物种多样性明显小于蕾铃期,优势种为丁纹豹蛛和草间小黑蛛;分析了丁纹豹蛛种群消长动态。
Based on preliminary investigation in fixed position in Dali Shanxi,there were more than 17 species of spider in cotton fields, which belonged to Lycosidae,Linyphiidae,TheTidiidae, Thomisidae,ATaneidae,Clubionidae,Tetragnathidae and Salticidae . The structure of spider communities in seeding stage were different from buds and bolls stage's. Analysed by Shannon-Wiener's species diversity index and Simpson's eveness index et althe species diversity in seeding were apparently less than in buds and bolls'.The dominant species were Pardosa T-insignita and Erigonidium gTamimicola. The population dynamics of Pardosa T-insignita in cotton fields were analysed.
