白花草木樨地蜘蛛群落结构及多样性

Structure of the Spider Community and Diversity in the Leucanthous Melilot Fields

白花草木樨地蜘蛛有11科31属41种,随着时间的变化,优势种依次为印痕球蛛(Theridionimpressum)、灌木新园蛛(Neosconaadianta)、条纹花蟹蛛(Xysticusstriatipes)和星豹蛛(Pardosaastrigera),蜘蛛的生物学特性、植被情况、食物供应和人为活动对蜘蛛群落结构和优势种群消长变化有不同程度的影响,分析的结果可为草地害虫的综合防治提供参考.

Totally 41 species of spiders belonging to 31 genera and 11 families have been found in the three Melilotus alba fields.The dominant species of spider communities were Theridion impressum,Neoscona adianta,Xysticus striatipes and Pardosa astrigera.The quantity fluctations of spider community structure and dominant specie were influenced by the biological characters of spider,the vegetations,the food sources and the human activities.Authors hope the result of the study would be of use in the integrated management and control of insect pests.
