| 摘 要： | 1979～1990年,调查了浙江省13个县(市)山地茶园蜘蛛资源,并在松阳县进行定点系统调查,共发现茶园蜘蛛24科110种;其种群数量大,占捕食性天敌的93.66％。优势种群有叉线金蝉蛛、前齿肖峭、突腹蛛一种、大井盖蛛、盖蛛一种、管巢蛛。室内饲养观察蜘蛛主要捕食假眼小绿叶蝉、黑刺粉虱、茶蚜,也捕食茶绿盲蝽以及尺蠖和卷蛾的幼虫。3种常见蜘蛛又线金蝉蛛、粽管巢蛛、毁坏管巢蛛对假眼小绿叶蝉的日捕食达8.5～11.0头,对害虫的控制能力居茶园捕食性天敌的首位,影响茶园蜘蛛种群消长的主要因子有:害虫种群变化、农药施用、农事操作及气候因子等。

| Abstract: | Field surveys were carried out in 13 counties/cities of Zhejiang during 1984-1990, with systematic samples taken in Songyang County to study the population dynamics of spiders. One hundred and ten species of spiders, representing 24 families, were recorded. They composed 93.7% of the total population number of all predators of insect pests. Six species, Phintella bifurcilinea, Clubiona delstrix, Tetragnatha praedonia, Conoplstha sp., Neriene oidedicata and Neriene sp. were found to be predominant. Based on laboratory observations, leafhopper, Empoasca pirisuga, the citrus spiny whitefly, Aleurocanthus spiniferus, and tea aphid, Toxoptera aurantii were the main preys of the spiders. Lygus lucorum and geometrid and tortricid larvae were also attacked. Changes of the spider populations were attributed mainly to fluctuation of the pest populations, pesticide application, cultural practices and climatic factors. |
