Abstract: Within the range of 20—35℃, the life span of adult spiders shortens as temperature rises, and males live shorter than females. The developmental rate changes with a turning point at about 25℃. The spiderlings could not normally mature below 15℃ or above 38℃. The 2nd instar spiderlings show the lowest average survival rate. The temperature threshold for development at egg stage is 12.44℃ , and for whole generation is 9.49℃. The threshold of effective accumulated temperature is 707.67℃·day. At 29℃, female spiders lay most egg sacs with most eggs as well. The hatching rate is the highest at 26℃.
