纵条绳狮的生物学研究

Studies on the Biology of Marpissa magister

纵条蝇狮 Marpissa magister(Karsch,1 879)在湖北省武汉市以幼蛛、亚成蛛和成蛛混合群体于 1 1月下旬在杂草根下部越冬 ,翌年 3月下旬至 4月中旬出蜇活动。 5月下旬至 6月上旬越冬蜘蛛开始产卵 ,在该地区全年可发生 1 .5代。雌蛛 1生可产 2～ 4个卵袋 ,单雌平均产卵量为 2 5 0粒左右 ,孵化率 97%以上。该蛛生长发育的最适温区是 2 5℃～ 3 5℃。

Marpissa magister overwinter in larva, subadult and adult mixed at weeds root holed in November in Wuhan, Hubei Province. Last tens period of March to Second period of April activate. Last period of May to first period of June overwintering spiders lay eggs. 1.5 generations bring about at this region, Female can lay two to four egg sacs. A female average egg number is 250.Hatching rate is over 97%.The optimum temperature is from 25 ℃ to 35 ℃.
