【摘要】 通过对沙打旺种植地的调查,发现有11科25属37种蜘蛛.7月上、中旬出现的优势种为印痕球蛛(Theridionimpressum),7月下旬出现的有条纹花蟹蛛(Xysticusstriatipes)和黑侏儒蛛(Meionetanigra),8月下旬偶见有田野豹蛛(Pardosaagrestis),但在4块样地内,自8月初到9月初,优势种基本上为条纹花蟹蛛.分析了蜘蛛生物学特性、植被情况、土壤情况和人事活动对蜘蛛群落结构和优势种群消长变化的影响,分析的结果可为草地害虫的综合防治提供参考.更多还原

【Abstract】 Totally 37 species of spiders belonging to 25 genera and 11 families have been found in the four fields of Astragalus adsurgens.The dominant species of spider communities are Theridion impressum,Xysticus striatipes,Meioneta nigra and Pardosa agrestis.The quantity dynamics of spiders community structure and dominant specie are influenced by the biological characteristic of spider,the vegetations,the soil and the human activities.The result of the study would make reference to the integrated management and control of insect pests.更多还原
