分布在雄性狼蛛前肢和触须上的化学感受器参与两性间的化学交流，但它们的分布模式和相对重要性尚不清楚。本研究利用扫描电子显微镜(SEM)观察了狼蛛雄性前肢和触角上化学感受器的形态和分布格局。我们还进行了行为分析，以确定它们在两性间化学交流中的相对重要性。虽然分布在男性前肢和触须上的化学感受器的精细结构差异不大，但触须上的化学感受器比前肢分布得更广泛。与前肢损毁和/或对照相比，化学消融PAPS化学感受器后，雄性交配潜伏期显著延长，交配强度显著抑制。因此，我们得出结论，接触性化学感受器主要分布在雄性触须上，从而雄性通过牵引线介导的雌性信息素来定位配偶。
The chemoreceptors distributed on forelegs and palps of male wolf spiders are known to be involved in intersexual chemical communication, yet their distribution pattern and relative importance are supposed. This study employed scanning electron microscopy (SEM) to determine chemoreceptor morphology and distribution pattern on male forelegs and palps of the wolf spider Pardosa astrigera. We also performed behavioral assays to determine their relative importance in intersexual chemical communication. Although the fine structure of the chemoreceptors distributed on male forelegs and palps did not differ greatly, the chemoreceptors were more widely distributed on palps relative to forelegs. When the chemoreceptors of palps were chemically ablated with zinc sulfate, male courtship latency was significantly prolonged and courtship intensity significantly suppressed as compared to those of the forelegs-ablated and/or control ones. Therefore, we conclude that the contact chemoreceptors are mostly distributed on male palps, thereby males locating their mates through dragline-mediated female pheromone.
