通过比较狼蛛科豹蛛属的星豹蛛和拟环纹豹蛛雄蛛分别在两种雌蛛释放的拖丝上的求偶行为差异,验证两种豹蛛雌蛛拖丝上化学信息物质在物种识别中的作用。研究发现,两种雄性豹蛛在同种雌蛛拖丝上的求偶潜伏时间都显著短于在异种雌蛛拖丝上的求偶潜伏时间,两种雄性豹蛛在同种雌蛛拖丝上的求偶强度都显著强于异种雌蛛拖丝上的求偶强度。可见雄性豹蛛能通过雌蛛拖丝上的化学信息物质进行种内识别。
通過比較狼蛛科豹蛛屬的星豹蛛和擬環紋豹蛛雄蛛分彆在兩種雌蛛釋放的拖絲上的求偶行為差異,驗證兩種豹蛛雌蛛拖絲上化學信息物質在物種識彆中的作用。研究髮現,兩種雄性豹蛛在同種雌蛛拖絲上的求偶潛伏時間都顯著短于在異種雌蛛拖絲上的求偶潛伏時間,兩種雄性豹蛛在同種雌蛛拖絲上的求偶彊度都顯著彊于異種雌蛛拖絲上的求偶彊度。可見雄性豹蛛能通過雌蛛拖絲上的化學信息物質進行種內識彆。

Chemical signals play important roles on species recognition,mate recognition and mate assessment. Current research in Lycosidae most focuses on the dragline-mediated chemical cues in mate recognition and mate assessment.Depending on the dragline-mediated chemical cues,male wolf spiders are able to discriminate sex,developmental period and female mating status. In the present study,in order to investigate whether male wolf spiders could discriminate conspecific females through female dragline-mediated chemical cues,we compared male courtship behaviour when males were exposed to the draglines from conspecific and heterospecific females between the two closely related species (Pardosa astrigera and P. pseudoannulata). Our results indicated that male courtship latency was significantly delayed and courtship intensity substantially decreased when the male wolf spiders were exposed to the draglines of heterospecifics females compared with those of conspecifics females. Male wolf spiders of P. astrigera and P. pseudoannulata are capable of chemically discriminating between conspecifics and heterospecifics females.
