摘要
圆尾肖蛸(Tetragnotha vermiformis)在我国广泛分布于棉田、稻田、森林、果园。该蜘蛛具有捕食多种农作物害虫的能力,在湖堤、河岸、沟边更是蚊虫的有效天敌。本文仅就圆尾肖蛸的历期和繁殖力与温度的关系方面的试验结果进行了整理,并力图建立相应的数学模型,旨在为保护和利用工作提供科学依据。
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℃.
