| 摘 要： | 蜘蛛的捕食行为,是直接影响捕食害虫效果的主要因子之一,也是人们选择有效的昆虫天敌的关键。本文记述了在自然条件下,肩斑银鳞蛛(肖蛸科Tetragnathidae银鳞蛛属Leucauge)的捕食行为。猎物以蚜虫、蚊子等小型昆虫为主,捕获手段多采用抓-拖出的原始方式;而对中、大型猎物则采用、咬、包裹等多种手段。捕食高峰多出现在早晨和傍晚。在捕食行为的进化上,尚处于从原始阶段到高级阶段之间的一个中间过渡阶段。

| Abstract: | The predatory behavior of Araneid is one of the major factors influencing the elimination of pests,and the key factor to select effective natural enemies of insects, This paper records the predatory behavior of Leucauge blanda (Tetragnathidae,Leacauge). The prey consists of small individuals as aphids, mosquitos, tec. When capturing small preys, this species applies mainly "Seize-Pull out" primitive strategy. When given middle or large preys, this species captures them by "Wrap-Bite" and various other strategies. The preys are most frequently captured in the morning and in the evening. The predatory behavior of this species should be situated in the transition stage between the primitive stage and advanced stage in the evolution of Araneids predatory behavior. |
