摘　　要：本文对隐蛛科的白斑隐蛛;狼蛛科的拟环纹豹蛛、星豹蛛、真水狼蛛、细毛水狼蛛;卷叶蛛科的猫卷叶蛛;栅蛛科的栓栅蛛;球蛛科的温室希蛛;皿蛛科的草间钻头蛛、难波小黑蛛、隆背微蛛、花腹盖蛛;园蛛科的黄斑园蛛;管巢蛛科的棕管巢蛛;蟹蛛科的三突花蛛;跳蛛科的吉蚁蛛等10科共16种蜘蛛做了在30℃恒温条件下的抗逆能力测定。结果表明,蜘蛛是一类抗逆能力较强的动物,只要供给水分,其雌蛛的平均寿命在25d以上;水在蜘蛛生命活动中具有非常重要的作用,在相同的条件下,如果断食断水,蜘蛛的平均寿命显著缩短,只有6d左右;由于蜘蛛种类和生活环境的不同,其耐饥饿的能力也表现出很大的差异,一般地面活动的蜘蛛或靠水边活动的蜘蛛耐饥、耐水能力较差,而游猎性蜘蛛,尤其是结网的蜘蛛抗逆能力较强;雌蛛的抗逆能力大于雄蛛;三突花蛛的耐饥能力随着龄期的增加而加强。The spiders ability of tolerating adversity was investigated at 30 ℃,we researched 16 specide of spiders which are belonged to 10 family including Nurscia albofasciata?Pardosa pseudoannulata?P.astrigera?Pirata piraticus?P.tenuisetaceus?Dictyna felis?Hahnia corticicola?Achaearanea tepidariorum?Hylyphantes graminicolum?Erigonidium naniwaense?Eigone prominens?Neriene radiata?Araneus ejusmodi?Clubiona japonicola?Misumenops tricuspidatus?Myrmarachne gisti. The result indicates that the spiders have strong ability to tolerate the adversity. The female spiders average longevity is more than 25 days if we give them water without food. At the same condition, the female spiders average longevity is only about six days if we don't give them water and food. So the water is very important in the spiders nature life. The spiders ability of tolerating adversity is different with the differeces of the species and habitat.Generally speaking, the web-spiders have stronger ability than the spiders which wander on the ground of live near the water, the female have stronger ability than the male. The ability of tolerating adversity increases as the instar rises Misumenops tricuspidatus.
