| 摘 要： | 圆尾肖蛸Tetrognatha vermiformis(Okuma)在武汉一年可发生四代,以低龄幼蛛在杂草丛中越冬.雌蛛一生最多可产6个卵袋,单雌平均产卵量154粒,最多可产466粒,卵的平均孵化率在85%以上.食物影响产卵量、幼蛛发育历期和存活率.温度对幼蛛蜕皮次数、成蛛产卵量、孵化率和寿命均有较大影响.幼蛛和成蛛能捕食蚊子、棉田和稻田的多种害虫.

| Abstract: | The spider, Tetragnatha uormiformis has four generations per year in Wuhan. The duration among generations is different. It overwinters at the stage of young spiderlings. The duration of the generations for the females is longer than that of the males. Each female can lay as many as 6 egg sacs. Each egg cocoon contains 64 eggs on the average. The average hatching rate of egge is 85%.Food affect the number of eggs, the duration of spiderlings and the survival rate. Temperature influences the duration of sloughs, the number of eggs, the hatching rate of eggs and the life-span of the adults. |
