蜘蛛具有一系列特征，这些特征在感官形态和性选择领域发挥着重要作用。虽然温度对蜘蛛捕食、建网、性信号和栖息地选择的影响已经有了很好的记录，但环境温度对蜘蛛求偶和交配行为的影响在很大程度上还没有被探索。为了确定温度对狼蛛Pardosa astrigera性行为的影响，我们在受控的实验室条件下，每隔4℃将成对的雄性和雌性蜘蛛置于16-32摄氏度的5个温度下。结果表明，在雄性中，除了血液扩张次数外，大多数行为参数都受到环境温度的显著影响。在16~28℃温度范围内，雄虫的求偶潜伏期、求偶持续时间和交配持续时间随着温度的升高而逐渐下降，而足瓣插入的次数和伸展的频率随着温度的升高而逐渐增加。(C)2009爱思唯尔有限公司。保留所有权利。
Spiders possess a suit of characteristics, which play important roles in the fields of sensory modalities and sexual selection. Although the effects of temperature on spider prey-hunting, web-building, sexual signaling and habitat selection are well-documented, the effects of environmental temperature on spider courtship and copulatory behaviours are largely unexplored. In order to determine the effects of temperature on the sexual behaviours of the wolf spider Pardosa astrigera, we subjected pairs of male and female to five temperatures from 16 to 32 degrees C at an interval of 4 degrees C in a controlled laboratory conditions. Results indicated that in males most behavioural parameters, except the number of hematodochal expansions, were significantly influenced by environmental temperature. Male P. astrigera courtship latency, courtship duration, and copulatory duration declined gradually with increasing temperature within the range of 16-28 degrees C, whereas the number of pedipalp insertions and frequencies of both pedipalp insertions and hematodochal expansions increased gradually with temperature.
